with only a $1000 to spend..best bet is to get another d series motor..
you can possibly do a b series swap..but I dont recommend going cheap.
to do b series..u need to find motor, tranny, ecu, axles, shift linkage, etc. just by looking at the list you know u will most spend more then $1000
I say get a jdm d15b..cost about 500-550..plus shipping...there will be parts u will need to exchange to make certains work..or do obd0-obd1 converison and get a obd1 ecu like a p28..
I can say from personal experience this is a good motor..I have done 2 swaps for friends with his motor..both are from
