How do I build the COLDEST air conditioner?
 

With the new motor, the A/C condenser must be mover out of the rear decklid. I have seen the under-belly units and that may be a possibility. Considering the motor is a '97 Varioram, what should I do to get some REAL air-conditioning in my car?

I had the rear fender condenser after I did my swap. In my opinion, it can't compete at all with the under-belly model, even though the rear one had a fan and the belly one is passive. In addition to throwing weight where you want it least, the rear fender condenser is trying to blow cool air on a condenser that's located right next to a hot engine and exhaust. Not a great idea, in my opinion.

New hoses and other components, combined with more condenser capacity, is the way to go -- again, in my opinion ("Pro Coolers" and shoe-horned condensers are not).

Also, in spite of the fact that I've installed the Kuehl vent in the center under the dash, I don't think it blows air where you can actually use it very much. Instead, it gets on your hand or is deflected by the gearshift. I think the most useful area for a vent is on the driver's side end of the dash.
