I installed a turbo clutch with the Fidanza aluminum flywheel into my '86 N/A and I love it! I ended up having to take the N/A ring gear and have the ID machined out to fit on the turbo pressure plate, and have 9 new counterbored holes drilled into it. The turbo ring gear wouldn't work because of the different # of teeth. The computer got really confused with the turbo ring gear installed, and would lean out the mixture at around 3000 RPM. It was so bad that it would backfire through the intake when you tried to rev it up. After converting it(correctly), the engine revs. up and down a lot quicker, and the car seems to accelerate a bit better. Double clutching on a downshift is definitely a lot more fun. At first, the lightened setup took a little getting used to when taking off on steep hills, you have to rev the engine a little higher to get moving. I have the S2 40% locking diff. transaxle installed, which is geared higher, so that just made it harder to get used to. Now that I have been driving it this way for a couple of months, I don't even notice it, but I cringe every time I get into my girlfriends '86 N/A. Her car is bone stock with an open differential and it feels lame in comparison. I am extremely glad I changed it over to the lightened flywheel and turbo clutch and would never even think about going back. The modified ring gear, turbo pressure plate, turbo clutch disk, turbo throwout bearing, turbo throwout fork, and the Fidanza aluminum flywheel were all that was needed for the conversion(minus the bolts and rear main seal).
