Is it necessary on a FI car (GSR motor)? what would benefit this over stock valves? Anyone got any insight on this on how much HP it would unlock? Right now I have a set of stock ITR valves shot peened and swirled polished, how much would stainless steel oversized valves perform better than what i have?

 

anyone?

 

hmm well.. i have a si head w/ oversized but its not on yet. any increas in airflow ona turbo car = haha thats the most lamen terms i could put it in since im 9 yrs old. larger exhaust valves frm what i know get the gasses out quicker..

i dont think ull see much diff though...plenty of ppl are running stock vlavetrains , go figure.
