i have an ls/vtec in my hatch. stock bottom end with pr3 pistons and a stock b16 head. motor runs real strong. from what i've been told by the guy that assembled it you don't wanna take it over 9k with stock ls rods. as far as putting it together or building one for you i would suggest B.R.E in Concord, NC. Tex built my motor for me. http://bremotorsports.com/
