    Evo1: 248/248
    Evo2: 264/248
    Evo3:272/264
    Late spec, Cecotto,Ravaglia: 264/248

      whats the best estimate that you could give me on how much it would cost to have the cams installed. My mechanic charges about $80 an hour. I would install the motorsport valve springs. So the whole installation process.

        I think John's got it right, except I am under the impression that even EVOIII's had 272/248 cam combo. As I understand it, only the intake cam was changed on all models, but they all still maintained the 248 spec exhaust cam.

        My car: 276/264

          It could well be a 248 on the exhaust of the EvoIII. That was the only one I wasn't too sure on, but I know it has a 272 intake.

            True all exhaust cams are 248

            I have 284/276.
