Hello,

I'm ready to install my CTR cams on my B16a1 with ITR outer spring on the both side. But for the inner i think to the portflow, but it is not much for CTR cam ?
Because i see on several post, the portflow + ITR outer can use with some st2 and more cams ... And i dont want to put too stiff spring because it's not very good ...
I'm previous to put the rev limiter to 9000 (I know, the power shut down approx 8000 but it's just for fun ....)

thanks,

 

you will be fine with the portflow inners and itr outers. It is a good reliable combination.
