ok guys... My new engine is with me right now. Everything looks to be very clean and nice. 100K miles on it, oil and oil filter in very nice shape, the TB with no oil, turbo blades are perfect, no oil on exh, just a little and common crack on the exhaust manifold soon to be repaired, wastegate in original conditions and seems to be never modified before, aux water pump works fine, the water temp sender to ecu is alittle cooked but I'll replace it by a new one, timing belt needs to be replaced, sparks looks like new, clutch disc seems OK, flywheel needs a repolish, gearbox looks very good... both came from a 94' UrS4. The A\C compressor is in the left of the engine...and my car has it on the right 
Ok guys... now I'll start with the questions... Instead of buying the stock clutch from the AAN... could I use the 2.5 10v TDi from the C4??? Cuz being a TDi it has more torque...so clutch is already prepaired for a big load of torque! Then... do I need to do any special mod to fit the UrS4 on my 1990 Coupe Quattro? If I do... please tell me how to do it!!!
Thanks!!!!!
