So I recently picked up a 93 90 cs Quattro, and the motor is toast. How different (if any) is the 5 speed trans in the 90 than the one that would be in my 1990 CQ? Is there a taller ring and pinion in the trans from the 90? Taller gears? Can I swap directly into the cq for a taller gearbox? I am going to put a 3b in the coupe, and I would love to have taller gears. If this is feasible, I will just part out the 90, and use the gear box for my coupe. Thanks!
