guys... the man isnt trying to build a drag car. He quoted somthing that read "heavy flywheel" and metal clutch. Hello, I dont think this guy is going to have 15" wide slicks and a metal clutch. NA drivetrain sucks major monkey nuts any way you slice it. I had a GTUs (N/A drivetrain) with a TII motor swap, the trans is the first to go in that situation, the rear second. If he wants speed its a full TII swap or V8 w/ that engines trans + TII rear and custom shaft. People have supercharged the crap out of the N/As and only seen 250hp. Bolt ons should suffice untill you have the bank for big upgrades. My sugestion is to enjoy the car untill you have the money to go buy a decent S4 TII. You can by an RTEK for that bitch and go crazy from there.
