I have just purchased a 1988 supra turbo.the only thing keeping it from passing "smog" is the timing. could someone please tell me what the timing mark is? I have looked everywhere for a manual, but I`m told I have to special order it. this would be greatly appreciated, thank you very much.

It should be 10 deg btdc at 650 rpm idle. To adjust it you turn the CPS just like you would a distributer.

Thank You very much for the quick response, You would`nt believe what I`ve gone through. I was beginning to think it was a highly guarded secret.... anyways, again, thank you so much!

Its no secret. If you pick up a $10 Haynes at the local auto parts store you would find the same info.
