I've been surfing Audizine a lot lately researching the audi engines and transmission for my swap. Another good site is 034motorsports.com because they sell a lot of aftermarket parts for audi's. When it comes to the wiring, you can either buy an aftermarket stand alone system or use the stock wiring system from the donor vehicle. From what I understand, Audi wiring systems are easy to separate the engine harness and useful wiring from the unneeded wiring. I can't answer what 4.2 engines are best because I'm going with the 2.7T but I believe both engine share the same bell housing bolt pattern and flywheel/clutch. This is strictly my opinion and haven't been able to verify yet. I believe you'll need to use an Audi flywheel and clutch no matter what. I don't think the Audi starter reaches far enough to engage the teeth on a Porsche flywheel. Both Audi 2.7T/4.2 and Porsche M96 motors have the pilot bushing in the flywheel. I'm not sure if the transmission shaft is the same distance to reach into the pilot bushing though. From what I can also tell, the 5 speed Porsche tranny should bolt up to the audi without any modifications. The 6 speed from a 2000-2004 will need to be modified for the starter. Starting in 2005, the Porsche 6 speed has the same transmission bolt pattern as the 5 speed. I will be answering these questions for myself at some point. My plan is to buy a 2.7T engine soon and see how well it fits in my chassis with the Porsche 6 speed. I don't think it will fit, so I'll probably end up going with the Audi 01E 6 speed trans.
What's the story with this picture and where did you find it?
