HP LS/vtec

[matts91hatchls]

im wondering what hp ill be at if i slap on a si head onto my ls with the ITR pistons... i was running 15.1 with my stock (ls), which converts with my wieght to about 138 at the wheels..... im guessing about a 10 to 15hp increase with the 10.8:1 pistons. and with a b16 head im hoping for about 200hp... which should get me in mid 13s.... what do you guys think? is it possible?...

Sure it's possible, but doubtful without cams... there's no way to know how much power you'll put down with a particular setup. There are way too many factors.

You'll put down good power with an LS/VTEC build no matter what. It's definitely worth doing. Do it, hit the dyno, and post the graph. And to answer your question, you're going to need cams and a good tune to hit 200 at the wheels.
