Hey guys, this fall I had a 93 S4 and loved it, but it was a little to big for my taste. What I want to do in the spring or maybe later this winter, is build a nice 90 coupe quattro. Im wondering what common problems are when they reach high power and boost. I am planning on doing some extensive engine work, Pistons, connecting rods, rings, injectors, valves and springs, cams and of course a thicker head gasket. What problems should I be looking for with the drive-line.

Suspension wise I would like to do full coilovers and camber plates along with some other fun treats.

Who makes nice engine internals for these or do I need to have them built at a machine shop? Also what turbo is popular for these I like the garret gt45s.

Also dose anybody know of 90 with a nice body near mass?

Yeah they sure do, ive checked them out before. What I am most curious is the drive line holding up. What are common failures, I am still pretty new to audis. BMW on the other hand is a different story.

01A and 01E will fail under this load. you will have to build up your trans aether way. cv axles and joints should hold up. diffs should be OK
