I have recently aquired a camshaft out of a 90 Daytona 2.5 Turbo (I) along with the roller rockers. I have an 85 2.2 Non-turbo. Can I swap cams and rockers without too much grief? I assume yes since the heads are essentially the same and all the cam journal measurements I took are within spec for my engine. The only differance I found between the 2 was the timing for the valves. The 2.5 cam is timed to open the valves 12 degrees earlier then my 2.2 (4 degrees BTDC for the 2.5 vs 16 degrees BTDC on the 2.2). I can't find any info on the duration or overlap for the valves on the 2.2. Any idea what I would set the timing at?

 

When the head on my 89 Daytona NA cracked and split the cam I replaced it with a turbo head and turbo cam (free parts are nice), it ran fine for the 6 months I drove it after that. The only thing I ran into was the cam sprocket teeth were different on the turbo camshaft than on the NA camshaft. I used the stock NA timing setting.

Cool, that should work (or at least give me a good starting point). I also found a "tip" on advancing the cam timing on Allpar.com. If anybody wants it I can post it.
