I made mine with black plastic plumbing tubing that just barely clears the heads with the trunk closed. My goal was to get the line close to the exhaust manifold--a trick I learned here on EM. The function is the reduce the air density, which the ECU will adjust the fuel air mix in order to keep a stoichiometric balance. The result seems possibly to be an FE benefit through reduced pumping losses. I should write-up my current design, but I'm still trying to figure out an easy way to switch from hotter to cooler air according to season/conditions.

I hear you. My AC was almost never used, even when I lived in the South. It never worked well and I don't like AC, anyway. I have not missed the back seats, but that's because I needed cargo more than seating. Without those deletes and others in the interior you have to go for other things to get closer to the 2094 stock curb weight of the 1992 VX. You took out the PS hardware? How about spare tire? Lighter battery? Rear window glass plexi/lexan substitution? Fiberglass or carbon fiber replacements for body panels?
But here's another thing... considered a SMALL turbo for low end power, like the super sipper TDIs have?
