funny!
I got some gsr cams, but I cant seem to find itr/ctr cams cheap. I bout that built head, that should give me about 30 extra hp, the gsr cams should help a little also, but all in all I am still using a blox turbo manifold, and a 2.5" catback, 2.5" dp with close loop dumptube. so there will be some restrictions.

 

00-01 USDM ITR cams are the same thing as CTR. As far as pricing... you can pick up used GSRs for $50 if you poke around.

 

I paid $80 for mines

 

Try and get a B17a1 GS-R intake cam...i compared my friend's b17 cam to an IT-R intake cam, and believe it or not the calipers said the gsr intake was a bit larger on the intake and duration.
