I spent several hours researching the matter last night, and here's what I found out. The clutch for the M102's is 8.5", and the clutch for M103's is 9", so they're not compatible. The 2.3-16 flywheel is the right size for the M103, but the crank sensor timing windows are in the wrong place. The original M102 flywheels, up through about 88(?) didn't have any crank sensor timing windows, and the 16v flywheel only had 2. The M103 needs 3 of them to run properly on the stock ignition. Flywheel offset isn't much of a worry, just those crank sensor windows/arches. Also, the flywheels were single mass up through 88 or 89, then changed to dual mass, single mass being more desirable.
So, if I want to do this swap, I'm going to need to find the flywheel, clutch, pressure plate, and all that jazz from a 86-88 M103 with a manual. If anyone has one or has any idea where I could get one for a reasonable price, please let me know.
And as for racing, this was a TSD Rally. Nothing terribly hard or hard on the car. I don't have the money to drop on a Getrag, and I can't see myself having that money anytime soon. I don't know how you guys do it, but I'm 20 and I work for Apple, but I still find myself broke every month working on this car.
