Yes, the rear controlarms ARE in the way. The inboard pivot points are too close together for anything except a Renault 5 engine & trans. BTMT

How do you figure this??????? Moving a front wheel drive
to the rear would work perfect.
DO NOT rotate the drive train. Just move it to the rear. I've stated
that this would be the best
setup here before. VW should have done this. A buick/old/chevy 3.8
L would be perfect.
A Nisson Maximum engie and transaxle is very compact and would be my
second choice.
Mated at the axles, cutting the rear deck out, and height would be some
of the critical issues.
Otherwise your going to get the same gas milage with a ton more speed
and HP. Silghtly
increased weight would mean better traction. One issue I have not
looked at is the
room needed around the front of the engine. rear control arms may be in
the way. If not
this may be my next converstion.

This transaxle forces whatever engine goes in there to run like a waterboxer - high RPM at most cruising speeds. This undoes most of the advantages of newer, more efficient engines, by forcing the newer engine outside its "best" zone. Most of the gearbox ratios can only be changed by a little. It helps, but does not solve the overall low ratio problem. If a standard FWD new transaxle is put in, it results in 1 forward speed, and 4 or five reverse speeds. This is a result of the differences in configuration and relation of engine/transaxle, and chassis between Vanagons and most other front-engine, front-drive vehicles.

That should result in a newer, stronger engine, AND more efficient gearing. All of this going in the right direction! Some of the advantages should be parts and service availability and lower cost (than a Porsche transaxle, anyway!) A bad point might be that the trans won't take kindly to running "backwards" all the time. Bearing preloads, and gear face angles are all set up with a certain expected orientation, and reversing them all may not work.
