If it is a 2G and has the stock turbo still which is a T25 you can beat it without nitrous or engine mods. My friend had all the bolts on his 95 Tsi AWD and ran a 13.71@95 with a 1.7x 60ft time IIRC and on the street he only got one car on me and then I had him every time by 100 and by 125 I had even more on him. I have the race vids somewhere plus his car and my car at the track.
My car at the time was a 1993 GT with ALL stock motor, exhaust, only 3.27 gears, and pulleys. I ran 13.80@100 best ET and my best trap speed was 103. Again, untouched 93 motor. It also had a full system in it!! I got crap 2.0 60fts at the track but hooked hard on he street with the 555Rs.
NOW, that same friend now has a Tsi again but this time a FWD one with a T28 turbo, cams, and all the normal bolts ons and traps around 110-112 easy.
