So what do you guys think would yield greater gains, fp red on stock cams or hks 272s with the stock turbo? Also which way would be more street friendly? Thanks guys.

 

Cams usually net around 40-ish whp if I'm not mistaken, so I'm pretty sure the Red would be good for more than that.

If by street friendly you mean low-end torque, then I think the cams would take this one; the Red is a decently big turbo, so it'll take a little while before it starts spooling compared to a stocker.

 

Cams would be more street friendly but of course, a bigger turbo will always give bigger HP gains but that's all in the higher RPM. I like how much faster my stock turbo spools up with just cams. At 2500RPM, I'm already at full 25psi on just stock turbo.

Personally, I can't go bigger turbo with stock cams. It just won't work out in the end.

 

I guess by street friendly i mean drivability and reliability

 

So I would assume the best gains are the cams and fp red or no?

 

Won't cams make your car sound and shake like a tractor at idle?

 

i drove an 8 with an fp red and hks 272 and precision 1300 injectors and it idled better then my sc cobalt on 60's

 

If you leave the idle stock, it can. But my Cosworth 272's idle quite smoothly. (Extra timing @ idle and rpm bumped up to 1k)

 

You can always turn up the boost on the red, cams will limit you. Id say go with the red its one hell of a turbo

 

go with a red then save up for gsc s2's

 

If you want the best bang for your buck right now I would go ahead with the fp red and then do the cams in the future. As those before me have stated, I would look at the S2's or something similar...you will have significant gains in the mid range and top end power over the HKS 272 with little or no loss in streetability/driveability.

 

Makes sense. BTW - your car is making nice power. No cat, I assume?

 

Damn, 2500rpm and full boost! Must feel mighty nice

 

That is correct. It's making ~345 now since I adjusted the tune a bit, wasn't comfortable running 24 psi all the way to redline on 91 octane & stock injectors.

 

FP FTW on MIVEC.
