Hi guys
I'm thinking about buying a cheap late Z3 2.2 sport roadster, whats involved in swapping the engine for a 3.0 M52 engine. Has anyone on this forum done this conversion ?
my Questions:
Are the gearboxes, diff (ratio), brakes, exhaust etc the same ?

Are you planning to swap from a donor car, or to get the parts individually.
I ask this because with the donor car option, it is probably easier to swap everything, whether it's different or not.
From what I understand, the main problem will be the ECUs and the ignition key, and the instrument cluster and mileage.
The answer to your OP is on realoem or any of the Haynes type manuals.

Very best of luck finding a 3.0 Z3 donor!
There are plenty of 3.0 M54 engines out there but the electronics they come with will be mapped for e.g. a 3 Series saloon.
You'd probably be better of just buying a 3.0.

AFAIK all the 3 litre engines are M54 so unless you find a 2.8 litre that has been modified to 3 litres what you are asking to do is not possible anyway.
You could buy a 2.2 and enjoy it for what it is since it is an excellent car in its own right but if you need more grunt then buy a 3 litre to start with.
By the time you locate a trashed 3 litre, and have paid a whole heap of money for it, so that you can swap most of the front end and anything else you need over what have you gained?
You will even have to insure it as a modified car whereas if you just buy a 3 litre to start with it can be insured as a standard car.
