The cam settings depend upon the turbo and general setup. What I'd try for a stock turbo isn't the same as what I'd use for a GT35R.

Oiy...good to know.

Did Piper give you any feedback about this? That is, if you contacted them...

does anybody have the spec on the Blox cams? their site just says:

Lift / Duration
10.8mm / 272 - Intake

Lift / Duration
10.2mm / 272 - Exhaust

i'm guessing they pretty much duplicated HKS so the spec should be the same but does anybody know forsure
