would i be able to put in ctr cams w/out a valvetrain.. if so would type r valvetrain ..springs and retainers. be suitable. noticeable difference over stock gsr?

 

Yes, your motor will accept the CTR cams just fine with no valve train modification.

And you`ll definitely notice a nice increase, however I haven't personally ridden in a GSR with the factory IAB manifold with CTR cams. Just B16's and GSR engine with the Skunk2.

HTH.

 

so you would agree that the gsr manifold is a POS....

 

had CTR cams on my gsr but i switched to a Junk-2 manifold and i liked them a lot. You will notice a good increase for sure
