vtec is always better than non-vtec.

i have yet to see a non-turbo put down hp numbers that vtec motors do.

its all tuning...and getting the air/fuel ratio correct. i have a friend running a built gsr turbo and with 5psi he's running with ls1's and lt1's from a roll.

with tuning, ie bigger injectors, he will bump the psi up to 10 and walk the same cars hes running with now.

i've also seen a b16a here in tampa that put down 406hp to the wheels. vtec is amazing technology...for those claiming turbo is not good with vtec...they're wrong.

basically, the duration of VTEC cams is open a long time for turbo

and because of this, you have that overlap.

it can be solved with a set of turbo cams, and cam gear timing.

That said, would I ever boost a VTEC?

if i was filthy rich, owned my own dyno, and was god of honda tuning.
