AFB rebuild or AKE swap on A6 Avant 2.5tdi Quattro - year 2000 140k
Would like some advice on the above
I've had this car for nine years now and it's part of the family - considered replacing it with a C6 avant 3.0tdi but prefer to wait for the new 3.0tdi BiTurbo.
The engine is showing it's age and just doesn't have the oomph anymore. it's always been serviced on time. My AFB only puts out 150bhp new so after a re map it's only going to get towards 170 - whereas the AKE with a hybrid turbo and map I'm assuming should be good for over 230 BHP. Whichever route I go I would want the base engine back to a decent condition so some form of rebuild is going to be needed.
If I can get hold of an AKE engine is it realistic of me to think I can get a good rebuild (lower bearings, rings, camshafts, seals etc for around the £6k mark. ( not including fuel system and turbo)
Is the aircon compressor on the AFB interchangeable with the AKE ? mine needs replacing and I'll get that done on the next service by VagTech but I don't want to put a new one on an engine I might change in a couple of months. Same question on the gearbox - will an AKE mate to my tiptronic quattro box.
Any and all views most welcome
