Audi Engine swap is it possible?

[ross-co]

Firstly I know anything is possible with enough time and money however I am hoping that this is a relativly easy engine swap.

The car in standard form is an 03 plate Audi A4 avant 2.5tdi quattro the plan is to put the engine in from an 05 plate A4 avant 3.0tdi quattro. About a 40BHP diffrence in the engines themselves in standard format however the latter is far better engine.

Does anyone presumably someone who has possibly worked on both cars know if it will be relativly straight forward with regard to engine mounts etc..

Thanks in advance.

there is an old addage: dont build what you can buy...

track down a clean 3.0 tdi and buy it instead, it'll be cheaper in the long run.

if not, there are lots of VW/Audi specialists capable of this swap, as engine changes are common in the modified VAG scene.

The problem is the A4 avant with the 2.5TDI is perfect and i doubt it will ever be sold from the household as it is just well...right i guess, there may also be more plans for it.

But i realise the sense in that saying but sometimes it is not meant to be.

You'll probably end up swapping the engine, gearbox, shafts, brakes, diffs, fuel system, ecu, dash...

We were thinking this might be the case,although there is no rush for the car to be back on the road so dare i say it it might be enjoyable.

The plan is to swap all the running gear aswell as the donor car has only done sub 30 thousand miles, instead of over 100 thousand on the 2.5TDI Avant.

It would make much more sense just to bolt on a hybrid turbo and map it. You'd se 30-50bhp more than a standard 3.0 TDi and pay less than swapping the engines over.

the 2.5tdi is not reknowed for developing big power easily or cheapily unlike almost every other TDi lump. 210bhp is about as far as you could go without significant cash spent. Then again if it aint broke...

The 2.5TDi engine is coming out as it is "broken" small problem but using it as a chance to upgrade.

Thanks for all the help so far.
