First of all thanks for looking.
Okay need some suggestions on what turbo to use along with anything I should take some regard to build before i boost. The motor will be STOCK, and im looking to make about 250whp. thanks , oh and also will be daiy driven.

i wouldnt go ls vtec then if its gonna stay stock and be daily driven. Thats alot of extra money youre wasting in my opinion. You can make that much with just the turbo and an ls motor thats in good condition. save yourself the money and the headaches and skip the ls vtec. with the money you save on skipping the lsvtec you can put it to building a better turbo and engine management.

So are you saying i should sell the b16 head for an ls?
Why wouldnt you go ls vtec turbo?

first reason i wouldnt do it is finances. It cost more to build a properly built ls/vtec motor that isnt gonna cause you problems. that money you can save and buy more parts like low comp pistons or have the head and block rebuilt so it has zero miles on it etc.

Second is that the stock ls already has a great compression ration for turbos 9:1. ls/vtec has slightly higher compression due to the dome shapes of the head compared to the stock ls. With a stock ls motor you can hit over 200whp with just the turbo at 8psi.

Third. with the turbo you dont need vtec. You really dont need it. If you leave the ls motor stock it still has decent power down low and the turbo will help you once it spools so exactly why do you want the vtec? If you have a relatively small turbo (a good one) it will spool so much quicker hence you arent gonna need a more aggressive cam profile for faster acceleration up top or for more power thats what the turbo is for.

Fourth. Ive seen some ls/vtec turbo setups that are incredibly fast and ive seen some that blow up incredibly fast. Honestly you can build an ls to be just as fast if not faster with a relatively less amount of money and less headaches.

Ide say keep the b16 head and peice yourself together a b16 on the side and take your time with it and drop it into another shell. No need to sell it but again ide rather turbo a b18 than an ls/vtec. For what you want you dont need it and its a waste of money.

Okay so you wouldnt go ls/vtec turbo if the motor was stock. What about if you were to build it what needs to be reinforced and built? Rod bolts? what?
Thanks for the feedback.

well first thing is that the head needs to be machined and prepped to be mated to the ls block the rod bolt holes dont line up so that needs to be fixed and the vtec oil supply line in the head has to be plugged and then an external oil line has to be run from othe head to the block. theres a sticky on ls vtecs in the teg forum on how to have a properly stock lsvtec built. and if you wanna do it properly you gotta dump a decent amount of change on it. before i built my old gsr i was gonna go ls vtec. i did tons of research and decided against it. built the gsr motor up and had a beast.

I have the ls vtec already in the integra, running and everything. What would have to be built for the motor to run reliable?

if its already in there im sure you could run something low boost in there and it wont blow. how much boost you planning on running? you have any plans for tunning?? depending on how much you want that will dictate what needs to be built.

Im planining on using Hondata s300 for tuning, Locash racing(Joe) will be doing it for me. Ive been looking at diffrent turbos and so far have found
T3/TO4E 50 trim with .48 a/r , and I found the T3/TO4E 57 trim with .48 a/r.
Which one should i use to get to about 230whp?

Turbo themselves im not too familiar with sry man. nick (njn) or one of the other turbo guys will be of more help than me.

deffinately start looking at compressor maps. It takes a little bit to learn how to read them but you'll thank yourself later when you have a turbo that is properly sized. I have to run to class right now or i'd look but offhand i'd say the 57 trim is going to be better but you might want a .63 a/r.

I really like this article: TurboByGarrett.com - Turbo Tech103

Just remember to leave some room for growth also because you're about $1000 away (assuming you have fuel management stuff already) from having a motor that could easily hold 400hp.
