Heres a few DIY tuning tips.......... for every car......

1.Port Matching

If you are lucky, the engine in your vehicle has exhaust and intake manifold ports that line up perfectly to the cylinder head. But chances are this isn't the case. You can pick up a few horsepower by carefully removing material in the manifold ports to match the gasket or the gaskets to match the port. This can also be done on the cylinder head.

2.Transmission Line Pressure Increase

This simple modification pertains to automatic transmissons only. By using a factory service manual and looking at the wiring diagrams, you can increase line pressure within the transmisson. This results in stronger shifts by simply adding a drop resistor that can activated with a relay and dash-mounted switch. Great little weapon for bracket racers, too

3.Get the lead out

If you are a bracket racer or racing fanatic, you should know that weight is the enemy. Removing your spare tire and jack can save up to 30 pounds. If you need more weight reduction, drain your windshield washer reservoir. To the average joe this sounds nuts, but you diehards understand.

4. Spark It Up

This is a simple yet overlooked tip that can restore a few ponies: pay attention to the condition of your spark plugs. Worn plugs wont make optimum spark. Also, switching from a conventional plug to an iridium unit may help. For a few more bucks its worth it.

5.Clean terminals= Happy Charging System

Over time, you will experience a negative battery terminal corrosion, which affects conductivity and looks unsightly. To avoid this, use an aftermarket terminal that has better conductivity and is less likely to corrode, or use a protective spray. You can clean up this mess with a mixture of water an baking soda applied with an old tooothbrush.

6.Replace Worn Ignition Wires

This is a no-brainer, but those NGK wires that use to be bright blue are now black should be replaced. If your ride bogs and just plains runs like it has twice its mileage, try swapping the ignition wires.

7.Redline Water Wetter

This product works wonders by raising the enegine's boiling point and increasing the cooling capacity of your coolant. This tip is used by many forced-induction fanatics.

8.Lower Tempature Thermostat

Head to your favorite auto parts store and see if it has a thermostat that opens sooner ) lower temperature) than your factory unit. If it works in your application, this will allow your car to run cooler sooner and can minimize power lost to heat.

9.Stay Lubed

One of the things top racers do is change their oil before and after each event. Having fresh, clean oil in your engine serves many purposes. For your street machine change oil every 1,500 miles.. For those that can afford it.

10.More Ground

A thicker ground on the Nissan mass airflor sensor (MAF) is a mod many enthusiasts perform. The factory ground wire on the MAF tends to corrode, casuing inadequate signal. Your car will run better due to the stronger constant signal sent to the ECU.

11.Gutted Air Box

For those tuners who desire maximum airflow but cannon use a cone-style filter, this mod is for you. Cut the sides of your air box abd replace the paper filter witha high flow foam or cotton unit.

12.Test Pipe

Removing your catalytic converter is the fast way to free up power. It's also the fast way to pollute the environment and get into trouble with the law. By using a test pipe in place of your cat, on race day you can have the best of both worlds.

13.Who Needs A/C?

Some tuners believe that air conditioning on a small displacement engine is a joke since it steals a considerable amount of horsepower an sends the fuel enconomy into the toilet. By simply switching off the A/C or removing the belt, you can free up more power.

14.Power Steering Deletion

C'mon you big burly man! You really dont need power steering in a civic hatch back. Regain horsepower-go manual. OE power steering has no place on racecars or high-performance applications in such little cars. When rebuilding, do it right and use the correct parts.

15.Big Wire, More Voltage

If in doubt, rewire your fuel pump for adequate voltage. you must use larger gauge wire than OE to wire large-capacity fuel pumps and relays. Be certain to follow install specs-even if it means running new wire from the battery source to the pump, rather than splicing into an existing loom. You will be glad you did.

16.Questionable Speed Washers

I dont know enough to fully recommen this practice, it worked for this talon owner: he devised his own "ghetto" boost controller, consisting of washers installed on his internal wastegate linkage. This opens the wastegate farther than the factory setting...

17.Remote Exhaust Valve Control

This product can be bought over the counter-or if you are creative , make your own. For quicker turbo spool-up (more usable power) use it to "dump" the exhaust after the downpipe from your turbo. And when you're done racing, your car is once again street legal.

18.Big Mouth

Do some reserach and see if another vehicle within your automaker's fleet has a larger throttle body that can be retrofitted onto your intake manifold. For example, the Type-R throttle body is larger than the b16A throttle body.

19.Throttle Cable

Examine your throttle cable; if considerable slack exists, adjust it or the throttle will not fully open when you floor the accelerator. Also, check that you are actually getting "full-throttle".

20.OverLooked Manitenance

Interestingly, some of the simplest power tricks full under routine maintenance. Havinga clean air filter, for example, will ensure that you are getting maximum airflow into the enegine. New fuel filters are also smart- and thats for starters. Good wiring connections ad preventive maintenance on life-cycle parts is also wise.


21.Get A Grip

If lucky, you could benefit from bigger brakes off a different vheicle. Do some research to see if there is some cross-pollination action in your near future. For example 300ZX brakes and calipers will fit on a 240SX. Enough said, go for it.


22.Rear Diffuser

This product is available commercially and has been used on many drag Hondas for years. This low-buck version is a series of 3-inch holes cut into the back bumper of your car, which allows air passing under the car to escape instead of pooling behind the back bumper ands causing excessive drag.

23.Nail A Wicked Hole-Shot

This is simple yet very effective weapon for front wheel drivers. For drag racing at the track, get bump stops and install them in your rear suspension. This will limit the rear suspension travel, giving you better hook-up. You will nail better 60-feet times


24.Tire Pressure

Having the correct tire pressure not only ensures that you get maximum fuel economy, but also the best performance out of your high-performance tires. Check tire pressure every two weeks and adjust accordingly. New rims will leak

25.Timing Is everything

If you have a good consistent grade of fuel where you live-or better yet 92 octane- then you can benefit from advancing the timing a few degrees to pick up some extra throttle respsonse and more driveability. Be sure to use a timing light!

26.Lexan Windows

Replacing your heavy factory glass with light weight Lexan will help your car in weight department (and hence, accelerate quicker) A lighter car is quicker than a heavy one. so call FAL (866-203-5958) If you own a 92-00 Civic. If not, make your own.

27.Brake Fluid

This is too often overlooked. brake fluid needs to be changed at least every two years and for a high performance vehical, every year. Use or upgrade to a high performance DOT4 brake fluid. Its easy as draining the old fluid (completely), replacing with DOT4 and then bleeding the system. NOTE: this may make your pedal feel softer and is completely normal.

28.Crank Protection

When installing rods into a freash engine, it's an old tip to install a couple pieces of rubber hose over the rod botls to prevent scratching the crank journals. You can buy them inexpensively, too.

29.Ram Air Scoop

This information is nothing new; nonetheless, it can be quite an effective addition. To pick up cooler outside air, make a funnel-like device that goes in place of the headlight or any other greille-area location that best fits your vehicle.

30,Custom Cold-Air Intake


If you have a car that doesnt have a cold-air application available from the aftermarket, design your own.


31.Keeping Your Cool

For high output application take " keeping your cool" one important step further and replace your factory radiator with a high-flow aluminum unit. Not only does it look trick, it tends to make your cooling system much more efficient

32.Header Wrap

If you have a turbocharged engine, the engine compartment terperature may have a tendency to get hotter than usual. One helpful tip to combat this heat is to use a thermal wrap on the downpipe, turbine housing and the headers.

33.Hood Washers

By placing washer between the hood and hood mounting brackets and using longer bolts you can lower the temperature of the engine compartment. Air will enter the engine compartment in much the same way as a cowl induction works.

34.No-Pop Oil Dipstick

The problem of the oil dipstick popping out doesnt happen to everyone, but if it does there is a small fix. Either put a small pinch in the top of the tube or use a wire ( or spring) to hold it in place.

35.Custom Heat Shield

There are companies that sell intakes with these heat shields, but you can make your own out of stainless steel or any other material for that matter- and for cheap. It can be as simple as a flat piece of material that isolates the air fitler from the engine heat.

36.Power Terminals

The factory terminal in Japansese vehicles its made as cheaply as possible, but by upgrading to a block style terminal accessories such as alternator, starter and other current demanding equicpment will get the proper amount of current. Yes, this does affect horsepower.

37.DSM Blow Off Valve

This modification is popular among the DSM crowd. Thee first generation DSM vehicles could withstand boost pressures to about 17psi. With careful mod, it can actually hold upwards of 20psi.

38.Reveres Bov On A 2Dsm

By reveresing the blow-off valve on a second generation Talon/Eclipse , you can run more boost than stock without buying an aftermarket unit

39.Hacked MAF

Another mod brought to you buy dsm guys: by removing the lower chamber of the MAF, air-flow can be increased substantially with minimal effort and a soldering iron.

40.Subframe Spacers

This can be bought or made and are used primarily on Nissans. The spacers pre-load the rubber bushings between the subframe and the body, thus helping to reduce wheel hop and body lean.

41.Bushings

For very little cost, replacing worn and tired rubber bushings with urethane bushings will put life back into your suspensio. In cetain applications, this will be a major performance boost in handling.

42.Engine Mounts

Sometimes it's the little things that make all the difference. When doing an enegine swap, using mounts designed for a swap makes things alot easier. Check this out prior to your engine install.

43.Toluene

Toluene is a solvent that can be found in more serious hardware stores across the nation. Adding 10 percent (by volume) of this solvent to a tank of, say, 91 octane gasoline should increase the rating to approimately 116 which is great for forced-induction or nitrous-powered engines. For about $3 a gallon, you cant go wrong- but it may not pass fuel check.


44.Propane Injection

This approach has been around for some time and is used with wet nitrous systems. Instead of using fuel, propane has an octane rating of 105 and allows you to get a fuel boost with out disturbing the air/fuel ratio.


45.No Fog

This is an old ice hockey tip. Tired of your visor in your helmet or windows on your street car fogging up? Take a cloth with a dab of shampoo and wipe the inside surface. Take a clean cloth and completely wipe off the shampoo. No more fog!

46.Redline Shock-Proof Gearl Oil

This product works great in transmissons that see heavy street racing or racing action. This oil features a solid dispersion that helps cushion gear teeth from shock loading. It also makes disassembly of the gear set easier.

47.One-Drill Drill Set

You may have seen one before. The Unibit is a stepped drill bit that allows you to make a different size holes (larger) with out the guesswork and with out changing bits

48.VHT Track Bite

This compound is applied to the drive wheels of a drag vehicle to improve traction on less than-ideal track surfaces. If you have a problems hooking up, this product can help. This is the same company that makes traction compound for dragstrip surfaces.

49.Wheelie Bar Sho Polish

You may have seen crewmemebers of pro drag teams applying a white substance to the wheels of wheelie bars. By using white shoe polish, you can determine for how long the front end is lifting; thus, it helps you fine tune your suspension.

50.No Drag

If you don't wish to cut up your bumper to minimize drag, you can close up these areas with a piece of sheetmetal. It keeps the air out and is virtually invisable to onlooks. Paint it black or body color.

51.Ground Wires

Think car audio. By upgrading the ground wires you alleviate the load on the charging system. Using a heavier-grade ( larger diameter) wire, you reduce the amount of electrical resistance. Since 12 volt electrical systems pull from ground, using this product makes sense and it does make dyno-proveb power..

52.Indexing Spark Plugs

This can be costly, plug wise, but worth it in the end. Using a marker pen, mark the procelain inline with the electrode. Screw the plug in the head and tighten. Make sure the mark aligns the way you want the opening of the electrode to face, favoring the intake valve. Indexing can be adjusted with various thickness washers or try more plugs. The are not all the same thread-wise.

53.Windage Tray

This decive is both simple and effective and, with some thought, you can fabricate your own. Basically, a windage tray keeps oil from spalshing up and hitting the crank, which effectively tries to slow the crankshaft, reducing power. Keep the oil in the pan!

54.Oil Pans

There are several companies making alloy oil pans for Honda, Mazda, Dodge, Toyota and Mitsubishi. These pans have a kick-out sump that keeps oil from splashing on the crankshaft. (Some will have a windage tray so if you have such a pan, eliminate tip 53.)

55.Short Shifters

Short shifters like B&M shifter enable quixker firmer shifts by reducing the amount of time required to select a gear. Positive shift stops are also helpful, but be sure to set them properly.

56.Acura Type R Shifter

This shifter is the weapon of choice. Pros such as gary Gardella call it " the best short shifter for a honda, especially for drag racing".

57.Cutting Off The Fuel Cut-Off
There are electrionic devices available that bypass the factory fuel cut-off limit on turbocharged vehicles. By using such a device on your modified engine, you can more boost with out having the fuel cut out on you. A very popular mod in the Supra and Dsm crowd.

58.Honda Shifter Bushings

More ofthen than not, these inexpensive little bushings can cause all kinds of shifting gremlins if worn out. Inspect and replace often.

59. Aligning Wheels

This is a must, especially on older cars or cars that are slammed. It is hard to go fast or for the car to handle properly when the wheels are pointed in the wrong direction or not in alignment with one another. Find an alignment shop willing to play with settings , as opposed to one that will use only the stock alignment specs.

60.Tire Pressure

Having the correct tire pressure on a street/strip car takes work to fight the right combination. Air pressure will be different in street trim compared to dragstrip needs. To nail a great hole shot, pressure will be lower than what is needed for road handling. Work on this one- there's alot of free performance here.

61.Lsd Swap

A great way to put power to the ground is to swap in a limited slip differential from an aftermarket company or if you are lucky, another model of your car for example, an LSD from a 95 Infiniti J30 will fit in a 240Sx.

62.Lose Weight Fast

Weight is the go fast enemy, so try replacing your conventional lead battery with a smaller, lighter gel cell or specialty-sized battery. Stay on top of maintenance, but every pound counts!

63.Octane Boosters

A subject of debate for some enthusiasts, but they do help if you don't have access to high-octane fuel. Forced-induction and nitrous powered vehicles can benefit from these cocktails.

64.Piston Install Tool

A simple tool that keeps piston rings compressed while inserting the piston in the cylinder. This tool prevents rings from being broken

65.Adjust Your Valves

Another routine maintenance procedure that can bring performance gains when done properly. Some vehicles are more difficult to adjust than others. All of them need to be stone-cold engines before any adjustments can be made.

66.Fuel Flow

Upgrading to a less restrictive fuel filter keeps your fuel clean and flowing. Also, be sure your fuel filter is not a restriction. Check this on a chassis dyno, using an adjustable fuel pressure regulator to help fine-tune your modified engine.

67.Reputable Tuner

This is a no brainer: your ride will only perform as well as it's put together and tuned. Spend the time and reserach tuners in your area. Talent comes with a price, so be prepared to pay if you want the best!

68.Ice

Very simple and free! Free our other favorite word other than sex. At the dragstrip a bag of ice placed on your intake manifold or intercooler can net you a few ponies, some days more.

69.Thermal Coatings

These products work the same wasy as header wrap, except it looks nicer and it lasts longer. In addition, the applications aren't only limited to exhausts. pistons and intake manifolds can benefit, too.

70.o2 Sensor

This sensor moniters the emissions of your engine and determines weather the engine should run richm leak or stoic. When the sensor wears out the car may go into "limp home" mode, where performance is noticeably decreased, but the car is able to be driven. Inspect every year and replace as necessary.

71.Rocker Arm Stoppers

This is something that is mainly used on Nissan Sr20Det engine. This product helps control valve-train floating at high rpms.

72.Reset Your Ecu

Some vehicles can benefit by resetting the ECU after performance modifications have been performed. This can be done by removing the ECU fuse for a period of time, then replacing it. If your vehicle has a knock sensor an the vehicle has ever detonated in its life you should reset this from time to time, it can place you into a "low power" mode. This is applicable to OBD-I.

73.Indexing Camshafts

Considerd crucial to making power when installing aftermarket camshafts, in actuality any cam must be properly inxdexed ( to the bottom end). As aftermarket cam profiles can be different from stock, advancing and retarding the cam(s) can also be effective.

74.Phenolic Spacer

This device can be made easily out of an non-metallic material. The idea behind this is to that it keeps the cylinder head from heating up the intake manifold.

75.Upgrading Your MAF

While this may not be applicableto all vehicles, it does work on some. By upgrading your MAF to one that is less restrictive, more power can be realized.

76.Truck Style Cooling Fan

Crank driven cooling fans were intended for big V-8s and trucks. If your car comes with one replace it with an electric fan. Not only will you get rid of that "whurrrrr" sound, you will also pick up additional power because the engine has one less accessory to turn.

77.Cam Swap

This is Something that isn't new, but if you are one of the lucky ones, you can benefit from cam swapping with an engine of a different year engine or engine model. One example is swapping out a set of B16a Cams for Type-R cams.

78.Swap The Hot Cam

like the previous tip, it is possible that the exhaust cam has a more desireable profile. This swap can be done by re-pinning the cam sprocket on some engines; on others it's even easier. See your engine technician and talk exhaust cam specs. You'll see what I mean.

79.Wheel Balancing

Drag racers have found this out the hard way; road racers have been doing it for years. Rather than statically balance (bubble balance) wheels, dynamically balance them. Drag racers have picked up as much as a .10 on the quarter of mile.

80.Knock Sensors

This is not for EVERYONE. Some owners in the 350z community have disconnected their knock sensors and picked up close to 10 hp. Apparently, the knock sensors are very sensitive to vibrations and pull timing back considerably. thus reducing power output.

81.Blizzak Racing

This is the poor mans drag radial. The soft compound of these tires gives you great grip at the cost of people laughing at you.

82.Copper Seal

This high temperature gasket maker is handy when building a custom turbo kit, as it can be used as added insureance against power robbing exhaust leaks.

83.Dust Off

This is a compressed gas that is found in art supply stores, used for dusting off art work with out touching it. In our case, try spraying it on parts that need to be need to be cooled, i.e the intake manifold

84.Trans Fluids

If you change the type of fluid in your automatic transmisson, this could result in better shifts. The accumulators react faster, allowing the various clutch controls to react quicker. This is due to the viscosity and friction modifiers in the fluid. Try it next time.

85.Two Step Rev Limiter

This feature comes with aftermarket ignitions, but it can be purchased separately as well. This device helps build boost on the line by spooling the turbo and acts as a launch control by enabling you to launch at optimum rpm.

86.Titanium Wheel Nuts

These are more expensive than regular lug nuts, but when you weight all the lugs together, they do help reduce un-sprung weight. Enough attention in these areas and presto, you got yourself a serious diet

87.Dont Drop The Plugs

When instaling spark plugs in OHC engines, its easy to drop a plug down the hole, potentially bending the electrode and altering your preset gap. To avoid this try using a length of rubber or sliicone tubing to pass the plug and get a few turns before using a socket.

88.Fiberglass I.C.E

Have your subwoofer enclosure made from fiberglass. It's considerably lighter than conventional wood/metal types and we all know how stunning thse custom inclosures can look

89.Yank The I.C.E

If your going racing, pull out the audio system in the back. This can save you 50 to 100 pounds by removing it. If its a duel purpose ride, install the equipment with quick disconnects, so it is easily removed.

90.Rear Camber Adjustment

If you have access to a die grinder you can grind out a portion of your rear upper control arm so that you will have alittle more adjustment. You will notice the inerference to be removed.

91.Intercooler Spray

Using a set of injectors or washer nozzle spray and a remote reservior filled with a mixture of water and alcohol, you can make your own IC spray for very little outlay.

92.Water Injection

A fine mist of water spray is injected into an engine to help reduce the chances of detonation. A great addition to any forced induction engine, but again, check fuel/air curve and overall boost on a dyno.

93.Stop Hose Blowing

Conventioal worm gear clamps don't do a good enough job of holding intercooler piping together. By replacing them with a T-Bolt style clamps, you will be less likely to toss a hose under boost.

94.OBD-II Data Logging

There are programs available for your Palm Pilot that actually alow you to read data acquired from the OBD-II ECU. This is useful when you have upgraded your car and want to see exactly what the ecu is doing. Programs such as Pocket Logger are available for both OBD-II and OBD-I

95.Claim Your Tools

If you work in a busy shop, it's easy to confuse your tools with someone else's. To avoid this, do something unique, like painting your tools a different color or add stripes, etc, to avoid arguements

96.Shoe Polish On Tires

This works for both autocross and drag racing. If you want to see how much sidewall rollover you are getting or how much contact the tire is making during a run, make a band with white shoe polish along the outside of the tire. After the run you will see how much is left. Which will what the tire is doing.

97.Relocated Battery

Not only does this clear up clutter under the hood, it makes it easy to plumb intercooler piping, etc. In some cars like AWD and RWD vehicles, it also helps traction.

98.Increasing Cooling Capacity

Do some research, you may be surprised to find that there is a larger radiator from a different vehicle that will fit your application. The improved cooling capacity will increase the longevity of your engine by keeping it cool. This is especially true if modified

99.Atmospheric wastegate

Not enviromentally sound, but yields decent power gains. The street legal way to do this would be to have a flapper valve that is controlled from inside which switches from atmospheric to non atmospheric . Usually good for 0.3 second in the quarter.

100.Stainless Steel Brake Lines

Everyone knows about this mod, but it is worth remembering that by replacing your flexiable rubber lines with braided lines, your brake pedal will feel firmer and more responsive. remember too, high performance racecars do not use rubber brake hose.

101.86-87.5 Mazda Rx-7 Injectors

These babies are 550cc low impedance injectors that can be found at a resonable price in wrecking yards. The should be cleaned and flow balanced before use.

102.Silicone Coolant Hoses

Yeah, they look pretty, but they also outlast conventional rubber hoses and are resistant to both oil and gas. Sounds like an easy decision to me.

103.Lose The Side Mount IC

Some cars such as the Talon/Eclipse, Corrado G60, and Sr20Det equiped vehicles come with side mount intercoolers. Take a trip to the wreckers and look for an intercooler from a Saab 900, Isuzu cargo truck, Audi 5000 turbo, or Mitsubishi Starion. All of these intercoolers are cheap and can be used as a front mount for better cooling of the air charge.

104.Intercooler Pipes
If your car comes with plastic or rubber intercooler pipes, upgrade them to alloy or stainless steel piping. The factory piping expands considerably under boost and that air pressure would be better served in the combustion chamber.

105.Port o2 Housing

This will work on just about any turbo machine that has this sort of setup. By porting the o2 housing, the exhaust flow will improve, thus allowing the turbo to spool quicker.

106.Stainless Steel Clutch Lines

If braided stainless lines work for brakes and you have a heavy duty clutch and pressure plate setup, then you should consider upgrading the pressure line that runs to your slave cylinder with a braided stainless steel line.

107.Cooler Oil

this is a definite must have if your car is force fed by a turbo charger. We all know that oil is the lifeline to your engine and the betterc ondition you keep that oil the longer your egine will list. Keeping your oil cool and installing a aftermarket oil cooler directly in the air stream is one of the best ways to protect your investment.

108. Eliminate HICAS

On late model 240sx hatches and 300Zx's came Nissan's version of four wheel steering. To some enthusiasts, its a pain: therefore companies like Stillen have designed HICAS eliminators, so the car behaves like a traditional front steering car. So much for technology.

121.12 Volt Treble Light

If you tend to take long trips or like to race at night, a treble that be connected directly to your battery is a life saver especially when wroking under pooor light conditions.

122.Remove 2g Bov Tube

This will make your blow-off valve more responsive by simply removing the secondary tube.

123.Lisele Panel Remover

This is another handy tool and one that is available at auto parts stores. This tool allows you to removed panels while minimizing the chances of breaking them or fasterners that secure them.

124.T-Taps And Scotch Locks

It may not be a good idea to use these types of easy fix items in high performance applications, since they can cause more headaches than you can imagine later on. Spend the time necessary to solder your connections then they are permanent fixes.

125.Baffled Oil Catch Can

Having oil enter the tintake tract can skew emmissions and even lead to deonation. By using an oil catch can that has baffles or breather, you can avoid this problem. This will also allow you to runa few more pounds of boost over a stock PCV-equipped car.

126.Restrictions On Boost Controller

On the Dsms you can remove the restrictor on the stock boost controller, which will enable more boost to be creaded on the stock setup.


127.Aftermarket Honda Cam Seal

These seals on the B-series Hondas are notorious for leaking and making a mess under the hood. Replace these stock seals with an aftermarket design (available from numerous companies) and you can easily solve this problem.


128.Cam Angle Sensor

If you swap out a first generation Dsm cam angle sensor and install it on a second-gen Dsm, you will be able to run more timing, which in turn will give you more power. A word of warning: this may turn on the 'check engine: light on occasion.

129.Check Ingnition Wires
If you are unsure as to the condition of your ignition wires, perform this simple test: take a spray bottle full of water an while its running, spray the ignition wires. It shoul dbe somewhat drak when you do this test. If you see arcing, you know that its time to replace the wires.

130.Torque Wrench

Every do-it-yourself mechanic should have one of these and learn to use it religiously. It can even be used on spart plugs. Everything on your car has a specific torque rating. Learn and use them!

131.Molyslip, Copaslip

This product is great for lubricating caliper sliders, as it will not clump up or corrode like some lubricants. As in any product, be sure of its application purpose, heat tolerance and its ability to lubricate throughout expected exposure.

132.Brake Proportioning Control

Want to have absolute control over your braking bias? Instale a bias controller that is adjustable from insted the car. Theres's also the wilwood proportioning valve, which is adjustable front to rear

133.Tire Pressure Gauge

Keep one of these inexpensive tools in your glovebox and check it religiously. For optimum performance and tire life, its essential that proper air pressure be used for the tire, rim width and the type of performance to which the tires will be subjected.

134.Piston Swap

Cross breeding occurs in all enthusiast groups. For Nissan 240Sx fans, you can take the Ka24De pistons and put them in a Ka24E for an increase in combustion: Type-R pistons in GS-R enegines and so on. Going with a high compression piston will give you a mild bump in performance, but check piston to valve clearance.

135.Disable Speed Cut

On the 240Sx the speed limiter is set at 115mph. If you race at the track and can exceed that speed, but the ECU wont let you, there is away around it. By unplugging the speed sensor on the transmission, you will loose your speedometer and cruise control, as well as the limiter but you'll go faster

136.Cheap Bolts And Tower Bars

Unless you shell out good coin for strut tower bars, chances are that the ones you have equipped with cheap weak bolts that will no doubt strip or break. Head to your local hardware store or fastener store and buy some hardened bolts. Look for five marks on the head of the bolts, noting that they are grade 8.

137.Purge

If you have a nitrous system, spend the extra coin and buy the purge valve. Not only does it look cool but it also allows the nitrous to hit sooner once the line is purged of any liquid. Best thing is to purge the nitrous a few times before you are about to launch.

138.Pretty Plumbing

If you have a direct port nitrous system and want to have a fancy plumbing, you need a line bender. Two different size radii can be made with this bender and it's fun doing it.

139.Oil On The Oil Filter

Have you ever had to really struggle to remove an oil filter? Solve this problem next time by applying a dab of oil on the rubber gasket that is located on the filter seal. This will help keep the gasket from drying out and will make removal easier next time.
