I would highly advise just hanging around the forums for awhile (especially this forum, the Civic forum, and the Integra forum) and asking general questions, reading info, etc.

It's blatantly obvious that you don't know a good deal about your engine or engines in general. If you just jump into modding, you'll either end up wasting your money on useless mods or you'll blow your engine damn quick. This isn't an insult, everyone starts at this point sometime, and you're just jumping into things a little faster than you should.

Did you buy the car with the b18 already in it or swap it yourself?
