I am looking to get some GSR cams. I am also looking to do LS Vtec.
I was wondering if these GSR cams would work without doing vtec?
And what kind of power gains am I looking at with this setup?

My Setup:
91 LS B18a, stock internals, Intake, Header, no cat, just resonator and muffler.
The head I would be getting to run LS Vtec is obd 0 b16 head, just stock enough to be able to handle the extra power from doing the vtec.

So again, what kind of power gains would I be able to expect from this setup?
Thanks!

The cams only work in VTEC heads. The only cams better than these (OEM) are the ITR /CTR camshafts.

You MUST do the LS/VTEC to use these cams

ok thats good to know...any idea of the power gains with basically a stock 91 b18a with LS Vtec and GSR cams?

i hope he was being sarcastic

typical LS motors put down around 115hp on a Hydro Dyno, a typical LS/V will do around 135-145hp on a Hydro Dyno, and alot of it has to do with the tune and the parts being used and the condition of the motor etc. It is significantly different than an LS but nothing to crazy

no by adding gsr cams to a lsvtec engine. with bolts ons dont expect over 180whp with all boltons. and dont use ITR or CTR spec pistons. be a man a bump the compression way higher
