I am planning on swapping my 85 2.2 Turbo Cam and Slider Rockers over to a 1990 Turbo Cam with Rolling Rockers. Dimensionally, everything should just drop in....remove the cam caps and swap everything. My question is regarding the cam sprocket and the effect on timing. I am planning on simply unbolting the square tooth cam sprocket from my 85 cam and bolting it on the newer 90 slider cam. Apparently, doing this will effect my cam timing by retarding things 4 degrees. Am I correct?
Is the solution to this using off-set cam key (like those provided by FWDperformance for $50) or is the solution to use an adjustable cam sprocket (also available for ~$130)? Of course I prefer not to spend any money.... Do I need the keys or adjustable sprocket or can I simply line up the cam timing manually as specified by Donavan on his webpage? (http://www.thedodgegarage.com/timing_belt.html) I do not plan on tweaking this after I have the timing set. I should continue to use the cam caps from the original 85 cam and not the newer 1990 roller cam caps? I know the difference in oiling channels but more oil on the cam is probably still a good thing, even though the roller doesn't need it. The engine in question is an 85 2.2 Turbo I. Plans are to convert it to a stage II calibrated TII in the very near future. I was going to do this swap prior to swapping the turbo and manifolds and other TII required parts. Anything else I need to be aware of? Thanks. -----------------------REMOVE-FOOTER-WHEN-REPLYING---------------------------- Questions?
