funny you should ask this. my friend is doing that exact thing right now. he went to a shop called trackmasters in sant clarita and saw a car there with 600whp from a turbo lsvtec that is daily driven. so he asked and now he is getting the same setup done in his car.
here is the setup in a nutshell from what i have heard..
ls block (bored to 2L)
je pistons(8.5:1 im pretty sure)
crower rods
ductile sleeves
b16a head(full head work)
type r cams
t72 turbo
etc. etc
now nobody argue with me about this because this is all second hand info and i cant reassure anything. the only thing i do know is that the guy with the 600hp civic is not lying. it really is 600hp running this supposed setup. ive seen dynos
