NICE car!

If you have an AAN, I would ditch the 10v motor and the CIS.

You could always get a custom intercooler made- are the front facing
manifolds still available from Germany? Someone was making a modded
intake manifold where the throttle body was relocated to the front, making
the intercooler path much shorter and also away from the turbo and exhaust
manifold. I would look into getting one of those, then getting a custom
intercooler
made (sheetmetal end tanks with an off-the-shelf core shouldn't be that hard
to procure).

If you run more power, I'd also look into having a custom radiator made-
everyone
seems to pooh-pooh the auxiliary radiator on the 20v cars, but IMHO there
was
a very good engineering reason for having the extra complexity- the car must
need
the extra cooling capacity so there is some margin of error, no? Having a
thick core
nice aluminum radiator will improve your cooling capacity.

Also, if you vent the driver's side wheelwell, you'll get better airflow
through the
radiator (I guess you've already done this mod).

Larger oil cooler will help as well, maybe you can fit one behind the bumper
if you can
somehow find the space.

Definitely the AAN motor, though- 20v head, direct ignition with a much more
sophisticated
ECU, availability of off-the-shelf software, etc.

If you do all of this work, it would really pay to get the 20v fender flares
or consider a full-on
V8 front-end conversion, so you have more space in the wheelwells. Also,
consider doing the
same in the rear, even though that a lot of body work.
