Alright, so I'm thinking of swapping a B18C1 into a 97 LX. About how much horsepower and torque could I expect after a 3" exhaust, a decent size turbo, lower compression pistons, turbo series cams, and better connecting rods? Thanks

 

depends on the tune you get. prob like 275-325 depending on turbo size torque i have no idea

3,000 rwhp




If you're really going to do all of this, I bet you would have already researched and know the answer to your own question.

 

b18s are good for about 150-160ish and you need to build it up for boost. I've seen civics with t3/t4 turbos on B18s pushing 300hp but it all depends on how you build up the engine and whos tuning it for you.
the turbos the easy part, just slap one on, and make sure its not running too lean or too rich. how much boost you can run depends on the build.
I've also seen alot of engines blow under boost so make sure you do your home work.
