I have the old school hks 272 cams and just did the fap and 11.5 cm exhaust housing on my ix turbo. I was wondering how close the advertised centerlines were for the exhaust cam (I have an evo ix). If any thing I want to increase my midrange by as much as possible. Right now my mivec map is based off the jdm rs map. Has anyone achieved any gains on an ix with hks 272 exhaust changes?

 

I would leave the Exhaust at 0. I might mess with the Mivec advance though.

 

well, i guess my question relates to whether or not zero really is accurate in these cams OTS. No doubt it runs good, but with the acquisition of the FAP and 11.5cm housing, I would like to be on top of my game. I mean i could just get the gear and install and test my self, now eh.. just probing the public first

I dont beleive my head has been cut or any thing to the block ,but I bought the car used with everything already installed.
