I am doing this conversion. It is very expensive. It would be much cheaper to 
do the 3B, AAN, ADU swap. I am doing most of the work myself, and the parts 
for the motor alone will be $15k-$20k. But I love this kind of challenge and I 
am taking my time, it won't be done for another 2 years or so.

I think Javad Shadzi is working on a 2.3L, but I don't know what it is based 

Here is a quick rundown of what my car will be:

Motor: (based on N/A 7A)
Goal: 450-500hp
2.3L - 7A (I have 2 of them, so I may as well play)
JE Pistons
Pauter or Carrillo rods
Knife edged crank (maybe)
Wagner intake manifold - Ported and extrude honed
Ported and polished head - 7A cams
Custom copper head gasket - PAECO Industries
Large throttle body - maybe RS2 (ported)
Huge intercooler
Custom equal length tubular header
Hybrid turbo
3.5" exhaust - side exit (in front of right rear wheel)
Stand alone engine management - Autronic or EFI Technologies (maybe 034EFI)
Fidanza aluminum flywheel
Spec Stage IV clutch

'90 Coupe Quattro
gutted interior
Race seats - Sparco or Cobra
5-point harnesses
Full weld-in roll cage
Autometer gauges
Deletion of power windows, door locks, sound system, alarm, sunroof, etc.
Lexan windows (maybe)
Fuel cell
Battery in rear
Fiberglass RS2 front bumper
Fiberglass S2 rear bumper
Fiberglass B4 hood
Fiberglass front fenders (maybe)
RS2 ellipsoid headlights
Porsche Big Red brakes
BBS Bugatti 17x8 et35 2-piece wheels
245-40/17 Toyo T1-S tires
Custom ARBs - adjustable

Well, that's the gist of it. As I said it will probably take a couple more 
years to finish. As you can tell, it won't be very street friendly (track car), 
but it should go like hell.
