Hi guys. I have a 2003 A8 with the 3.7L engine and GQE gearbox. Now the gearbox is troubling me (I have another thread on this) and I've been offered the 4.2 engine and gearbox for quite cheap. I've been searching but it seems no one else had done this.
Firstly what parts would i need in order to do this swap other than engine and gearbox? (For a start, the guy selling it suggests i won't need the ECU which seems odd to me. He says i just need the wiring loom and i can plug that into my existing ecu. If that's somehow correct, i would prefer this). From initial thoughts, would i need the keys and ignition system from that car? And are the radiator and cooling system, brakes, suspension, etc. All the same? And the main drive shaft, diffs, etc. (My car is a Quattro, so that might be something to bare in mind).
And secondly what would i be getting into with the swap?
Thanks in advance.
