Looking for feedback from anyone who has used HKS step 2 cams with 2860r-5 turbos. This is for a 2.7l non stroker built block with mildly ported/polished head. Machine work done to accept these cams (272 10.25) including HKS springs. Is this too much cam for these turbos. All other supporting mods done (ECU, exhaust, fueling etc).
