how unrealistic is this dream of mine? I know you can get more if I had a larger turbo but I don't even have a 10.5 hotside. I think it's safe to say I will gain 25whp and matching torque from the HKS 272's if tuned correctly but what about revolvers? Timcatz seems to like way over HKS. So what do you guys think?

 

For you to get that kind of gain you would have to have a serious restriction with your current setup. i.e. if you have a GT35R with stock cams you would flow a significant more air with the upgraded cams through the head.

 

yea i don't believe the hype but my friend is getting them soon so will see
