Hold on. You have 2 Audi V8 notified to choose from? Did I read this correctly. If so I'm following closely. This swap if completed is exactly what I want

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.

Looking ahead, I plan to install a 5 speed transmission from a 2001 2.7L into this car. Yes, it's not as robust as the 6 speed, but it works and the 01A Audi version has been paired with this motor many times without issue. I haven't researched any of the details of how to make this work yet. Feel free to post any tips, trick, or warnings for me to consider, or preferably a complete DIY with pictures that a 5 year old could follow.
I think I have everything from the 2001 available including axles and clutch slave. Everything for the 6 speed is currently in the car and operating correctly.

• I think that the transmission suspension/mounts for the 5 speed will be a direct install.
• Have not looked at shift linkage. Issues?
• I'm guessing the clutch slave just needs to have the hose connected.
• Axles... Haven't looked yet, but I'm hoping that I can swap the ends from one to another. If that doesn't work, I may look at some Audi parts. I may want an output flange with a heavier coupling than the 5 speed currently has. Will the flanges from the 6 speed install in the 5 speed?

Any thoughts?
