So it seems to me like the 987 transmission introduces some issues that maybe haven't been foreseen? Maybe these arise from a difference between the distance from the transmission flange and the throw out bearing and/or the distance from that flange to the CL of the crank position sensor?
I thought the crank position hole was a standard location across all VAG product transmissions. If they've moved it longitudinally, this also brings up the possibility that it is in a different location radially as well. This would throw off the ignition timing, and everything else that runs off that signal... obviously. Did you notice anything like that?
The good news here is that I'm picking up a flywheel and clutch from a 2.8L 30V this weekend. This is the flywheel setup that is recommended for B5 A4 V8 swaps where guys retain the original 01A transmission (I'm using the FWD variant of that).
This setup does not need the spacer between the engine and the transmission and yet is interchangeable with the same transmissions that the B5 S4 flywheel/clutch is, when the spacer is used for the S4 stuff of course (because we know that you can use the B5 S4 stuff on the 01A if you use the spacer).
So the conclusion here is that the S4 flywheel and clutch necessitate the spacer to increase the distance between the throw out bearing and the pressure plate face. The S4 stuff is very long in other words.
I suppose in theory if you use 2.8L flywheel you will be gaining that distance that the spacer adds. If you use the spacer in combination with the 2.8L flywheel, you'll be gaining even more distance yet.
2.8 30v Clutch Questions...
I shall install said flywheel and provide you with measurements good sir!
