I took some measurements from my block, bellhousing, 89-94 maxima pressure plate, and S15 flywheel. They aren't quite accurate to the 128th, but very close. The crank hangs out 14mm past the mating surface of the block. The metal shim plate that sandwiches between tranny and motor is 1.5mm thick. From the block mating surface of the 6 speed tranny to the farthest depth you can physically push a clutch in is 105mm. From the clutch friction surface of the S15 FW to the crank mating surface is 45mm, and the ring gear hangs back 7mm behind that. The overall of the Max PP is 53mm thick. So what I'll be doing is having 3/16"(approx 4.5mm) machined off the face of the FW, and using 2 of the metal shim plates for an additional 1/16"(1.5mm) of tranny to motor spacing. I'll also be flushing up the lip' that curls out in front of the PP release springs, to the front of the PP. This will give me about 2mm of room to play with. It'll be tight, but should work just fine.
