Engine Question
I have a 1990 Audi 90, and have been told that i could drop an old S4 or S6 engine in place of my current one. Does anyone know if this is true and if so which model and year. I was thinking like a 1995 S6. Also if this is true where can I get one?

"Drop in" ?
Uhh, in a word, no.
I mean, anything will FIT, but you'll need the ancilliary electrics and so forth. It would be a plumbing nightmare.
What you can do is put in a turbo I-5 from a 5000 or 200. Still a fair amount of work, but much easier. The engines are also far more plentiful. Where would you find these 'S' motors I wonder?
Such a project will cost what your 90 is worth at a minimum, so it's probably easier and more cost effective to just buy the car you want.

Dwight's partially correct (more)
The S4/S6 20v turbo engine is not a drop in replacement, but it will fit in your car. It's been done with a couple Coupe Quattros with the same chassis- Brandon Hull and one other person come to mind. However, bear in mind that a complete engine (you need the wiring harness and the ECU) will run you upwards of $3500 (that being a low figure, I think). Also, the labor involved is quite extensive.
I would search some of the quattro sites to try and find an engine. KAR in MN has a '91 200q engine, that would work in your car. I think there are a few more of these engines around, you just need to do a lot of legwork to find one.
That would be pretty sweet to build an S2 sedan (essentially what you'd end up with if you did the complete conversion).
Where are you located?
