The not quite S

Hold on. You have 2 Audi V8...

Yes, I have a 1998 ABZ engine and a 2003 AUX engine and a flywheel & clutch arrangement for each.
Originally I was working with the '98 engine, but now I have both and think that the '03 engine will be a better swap for the 2000 model car. I expect that after I get the swap all worked out in the 2000 (mostly for track), I'll start working the ABZ into one of my 99s as a more 'polished' street car.

For me this is a very slow process, but I will make updates.
Audizine has a few good 4.2 swap threads, but they are mostly into A4 sedans.

I've also watched a Cayman swap on Planet 9.

I can't find any detailed Boxster 4.2 swaps that were completed, but love to look over the pics that kcpaz posted. http://986forum.com/forums/boxsters-sale-wanted/63028-fs-boxster-s-race-car-audi-4-2-v8-engine-lots-motec.html
Mine will not be a polished professional job like that, but I'm hoping to make a rough looking, solid performing track car that can be driven on the street.
