W124 E220 coupe engine conversion

[liiive_o]

hi everyone

i have a couple of questions and would really appreciate some help and advice.

I have a w124 e220 coupe 4 speed auto...
im looking to get an engine conversion,an e320 which i want twin turbo charge at a later stage.

whats required to change? i have found a good e320 engine from a saloon...is that possible?

Its a major job to do it right. Your best bet is an entire donor car to get all the bits required. So many people who have tried this have run into snags that I would advise buying a car that is bigger engined model from the factory. Insurance companies prefer this also.
To give you an idea are you prepared to change the following.

Engine, gearbox, injection system, ignition system, ECU and associated electrics, front suspension, front brake assemblies, prop shaft and rear diff?

That's what you are looking at for sound transplant. Sorry to disappoint you but it could save you lots of heartache along the way.

As with any engine conversion, better off buying another car with the bigger engine, especially in todays climate of cheap big engined cars. Less over all cost, much less heartache and much less to go wrong...

no real knowledge on this myself, but from what i have read on here in past threads, its often easier and cheaper in the long run to just buy the 320 car.

Anything is possible, but the question's I ask are. Can you afford it? Your car will be off the road for some considerable time. The parts you require will cost more than you think. Your insurance is going to hit the roof. Your fuel economy is going to go into low double figures (if you are lucky). You will end up buying all sorts of tools that you would probably never use again. Lastly, do you have the space to do this?
