putting a TT rear end on your n/a will DECREASE performance dramatically.

the TT rear end has a 3.69 final gear ratio and the n/a has like a 4.2 or something like that.

if you do a TT conversion you will want to keep your N/a rearend and get a custom driveshaft amde to fit. unless of course you really want a very high top speed. the n/a diff. will make your car accelerate faster than a normal TT but at the sacrifice of top speed.

personally, im keeping my n/a rearend and getting a custom driveshaft made.
