Thanks guys, its a great car.........there were about 50 E31 TT's made by Dinan however only 5 of these were the big Hp 5.7 stroker motor Stage 3. There are now only 4 left since # 5 was totalled by its owner in Hong Kong. The regular TT makes approx 511 Hp with a Stage 2 making approx 550 Hp and the Stage 3's making approx 625 Hp.
Have plenty of pics but cant post...........I'll send them to someone if they can get them posted.
