I had it done on my 90 NA which I sold early this year. Initially, it took almost six months to workout all of the kinks (wiring and so on). The car seemed slower and did not have the torque that I had with the auto. If I had to do it again I would just buy a 5 speed. Driving 5 speed is awsome and is definately more fun than an auto but the conversion is full of head aches and definately requires patience.
