anyone put a m97 or mA1 in a 986?

In two words: Good luck. The new A96 cars are running Siemens management, not Bosch as all previous cars did. The engine management is COMPLETELY different. I can't even begin to imagine how much of a 9X7-2 car's electronics you would need to make this work.

Pardon my ignorance, but what's a mA1 engine?

The 987.2 and 997.2 engine.

Can you use an aftermarket ECU? Motec can run a throttle by wire engine with variable valve timing. Not sure if anything special is needed for the high pressure fuel rail.

I would think Motec could do this, but would require quite a bit of tuning to make it work right.

I just don't see why you'd want to do this swap....

as far as I can see, the newer engine(987-2 3.4 as in the spyder) with headers, free-flow exhaust(no catalyst), and an aftermarket controler would give me more power than I could get out of any m96/m97 boxster/cayman engine with no internal modifications. If I were to swap in any engine from a 996 I would have to race in classes that are pretty much unlimited race only, stripped out specials. this is the only class other than stock that a street boxster can race in, and unfortunately, all boxsters and caymans are calssed together, but I am allowed to update the engine, and or transmission assembly, etc.. I also can run any induction or exhaust that meets noise requirements.

I would think the easiest thing to do though would be to retune the siemens unit , and delete some of the auxillary functions(catalyst monitoring, AIR, etc.), while maybe adding varioram if not equipped, and using an intake setup from a 997s with varioram.

or maybe an aftermarket setup, like motec, with individual throttle bodies on each port, with the plenum above, kinda like the bmw m-motors were.

I'd be very interested to read these rules.....
