In addition to gaining some much more desirable gear ratios, center locking and 4:11 S4 final drive in this conversion I also picked up some dramatic rotational mass weight reductions.

90Q dual mass flywheel: 34.9lbs.
200TQ cast iron single mass flywheel: 17lbs lightened to 12lbs

Stock 90Q CF 2pc driveshaft and CVs: 29.70lbs
Lightweight/motorsport Driveshaft/CVs: 15.14lbs

Total rotational mass weight-loss achieved from flywheel to final drive during 016 tranny conversion: 37.46lbs

Far better gearing with a 37.5lb rotational mass weight reduction is no small/subtle achievement on any car, let alone a dual purpose one. When added to the additional 36lbs of rotational mass I'll lose with the new engine this car should be VERY quick to rev and decelerate when revving freely or under load. The 11.25:1 compression should resemble Jake Brakes when decelerating in gear.

Hopefully today I can finish up under the car by installing the drive shaft and finish welding the right side tranny mount and get it installed. Both tranny mounts were designed/fabricated to allow it to be 1/2" lower. I've turned 1/2" spacers to shim it back up til the engine conversion when I can machine motor mounts to allow the engine to drop a corresponding 1/2" for lower center of gravity.

Today I should be able to start my "least favorite" aspect of this whole conversion, ie; adapting the shifter linkage to work in the 90Q while also appearing 100% stock. Besides the Bilzcat stainless short shifter I have to use bits/pieces from a 96/97 A4QM, my 90QM, an 00/01 S4QM and of course the 4kQM. As is my nature on mods like this I saved the worst for last.

is the engine install still anticipated for the spring? early/late, dunno what your timeframe was...

soon as pistons are in-hand then balancing begins and then reassembly can commence. But I'll probably take 2-3 months for reassembly as every single component must be measured, test-fitted and plasti-gauged before final assembly.
