I currently have a complete JDM ITR head on my b17 but just bought a BRAND NEW COMPLETE USDM ITR head that i will be using. I want to go with come Skunk 2 Stage 2's with my 11.5 compression but is the factory ITR valvetrain enough to handle these cams or should I upgrade? If I should upgrade, what do you recommend? Thanks guys!

 

on my itr motor i have ferrea valves,s2 springs and retainers, and i feel safe with my ctr cams ,personal opinion i would upgrade u could have spent your money better on the jdm head

 

u need too upgrade...im wonderin..why did you buy a new itr head when you already have one......?

 

you need springs at least. I think itr retainers are good till 9500, but I'd get the skunk2's while your at it. You'll probably want to think about bigger injectors and some kind of tunable ecu such as hondata, uberdata, or at least a vfac. Good luck, do some research on those cams, or any cam you plan on runnning to make sure you know what your getting into.

yeah but the JDM heads aren't new. For a couple hundred more, I decided to go with a new head. Im building a new motor and wanted to start off fresh. Peace of mind also made me go new. NO questions with 0 miles
