If your goin to go all motor, i definitly would not start off w/ a b16 if i had the option. Ls/vtec would definitly be better, but depending on how crazy u want to go w/ the all motor build, it might just be easier to go w/ a gsr motor. If ur wanting to do some crazy stuff like vteckidd's ls/vtec then yea, the ls block will help out, but otherwise i dont see why you dont just go w/ a gsr. You can still get over 200 whp.
