Any progress on V8 engine swap options?

[truegearhead]

There seems to be endless Audi 4.2l options. Is there a year/model you want to stick too? Looking at the horsepower figures an 04 or later is good, an S8 is ideal and I guess the drive by wire or cable decision needs to be made. Am I missing anything? Has anyone attempted to proceduralize the 4.2 swap, even from a high level?

What flywheel and clutch did those of you use that swapped in an ABZ motor? I was hoping I could use the Boxster setup but its an 8 bolt and not a 10 bolt flywheel

This is what i used:

Audi V8 4.2 10 Bolt to O1E/O1A Gearbox | TTV Racing Component Flywheel & Clutch Manufacturers

paid around $500

Used an Audi B5 S4 pressure plate with a 987 Cayman S friction plate in to a 987 Cayman 6 speed box

Do you know if a Boxster pressure plate and clutch plate will work on that flywheel?

The Boxster friction plate will work. Not sure about the pressure plate. Looked kinda similar, but did not try it. Email the guys at TTV - they custom make them, so chances are they will make you one that fits the Porsche clutch if you send them the details.

You are best off looking at the C5 A6 and S6 variants of the 4.2. S6 has forged rods i believe and a better cam setup that makes more high rpm power. The D2 S8 version makes the most power from factory (same upgrades as S6), but uses a different mount setup, which can be swapped to the A6/S6 version relatively easily. The older ABZ works with a standalone ECU, but the stock ECU cannot be easily reprogrammed like the motronic ECU you get in the 2000-2004 cars. The 2004+ 4.2 engines are timing chain rather than timing belt, and require very expensive engine out service at around 100k miles, those would not be good engines for a swap for the most part.

Member AaronF who posted above has the best info I've seen for the swap, here:
