The most often used clutch upgrade from the 1.6 clutch in a vanagon is to use the TDI flywheel, VR6 pressure plate and heavy duty WBX 228mm disc. That will hold back at least 250ish ft-lbs of torque and you really don't want to put more than that through the vanagon trans. You need bend down two tabs and clearance a little on the inside of the bell-housing and nose of the starter.Don't forget to install a pilot bearing in the end of the crank...

Burn, the vanagon pilot bearing is a very common part that is installed in the end of the crank of all the early longitudinal VW/Audi 1.6 diesels (quantum, vanagon, dasher, 4000, etc...).

I have it in my 01 TDI and it feels like the stock one, except the stage 2 tune doesn't slip on this one. All in one nice bundle and you can get the lighter flywheel if you wanted. At 14 lbs it is a tad heavier than the stock 020 210mm setup.
