MSD Ignition???
I would not even consider downgrading to an MSD setup on a 964 though. Ask around and you will find that the dual-distributor/plug setup on a factory 964 is one of the finest and most expensive systems out there. I hardly think that upgrading to another ignition system would be that beneficial and simple...it is computerized.
My advice would be to spend your well earned "upgrade allowance" elsewhere, like an exhaust upgrade or chip??
Mind you every setup has it's issues, the distributor belt being one of them on a factory 964 ignition...but that's minor! Just get a new belt installed if you're concerned about it...and certainly get the upgrade to "vent" the distributor housings.
That's just my 2 cents for all it's worth.
