I have seen pictures of how to tell the difference but was wondering about ITR cams I know about 97 spec and 98 spec Is the '01 ITR cams different or '98 spec? Found some that I might look into buying then sitting on them until I get at least some springs. Some say you need the lost motion assembly for the type r too b/c the B16's are not good enough (maybe not firm enough?). Some say you only need the cams and springs....others have stated that you only need the intake springs and take your B16A intake springs and move them to the exhaust. Please feel free to state what yo've heard...or, preferably, felt and been witness to.
