An MSD 6AL is not compatible with Motronic AFAIK.

Pelican shows the MSD 6420 as working on all models of 911. I do not know if it will work on your vehicle or not. Double check with your vendor.

Why are you moving to an MSD? What are the symptoms/issues you are attempting to address?

I am thinking may be get more torque ,
It is Mistake ??

I do not know. Most people seem to go this route to replace a permatune (I do not suggest using this product) as the Bosch unit is a bit pricier. It seems to be done more often than not to address an ignition issue.

I would suggest posting on the engine re-build side and get some opinions there. Hopefully someone more knowledgeable will chime in.

I think diminishing weight will get you more bang for your buck initially. There are many older threads on weight reduction techniques.

MSD = Multiple Spark Discharge.

MSD basically causes your spark to discharge more, thereby getting "better" combustion. Or more efficient combustion. Or so they say.

Actually - with your Motronic, that's what it does too - monitors engine efficiency and adjusts fuel and timing to compensate.

I don't think it gives more torque.

MSD is great for old cars as an upgrade. MSD is good in the right application for newer cars. I've installed a MSD coil pack on my wife's R50 cooper, and I see a difference in fuel economy.

From what I've read, MSD is fine in a 3.2 911 if your Bosch motronic brain has kicked the bucket. Otherwise, you'd be better off looking at other ways to improve engine performance - like getting your engine to breathe better by making adjustments on intake or exhaust side of the engine.

But - I'm not an expert.

Good luck.
