Engine change

Recommended Posts

Hi all,

im toying with the idea of dropping a 330 lump in my 320.

My question is other than the engine itself what else needs changing?

 

As both engines are 6 cylinder and think both are M54, will the gearbox and exhaust all be the same?

will the 330 lump run with the ecu that’s currently in my 320?

 

thanks in advance 😉👍

I'd have thought you'd have to change over everything to do it properly..

Engine
Loom
ECU
Gearbox
Exhaust
Driveshaft
Diff
Half shafts
Brakes

And likely suspension too as the 3.0ltr is much heavier than the 2.0ltr.

I'm sure you could get away with the bare minimum like engine/gearbox/ecu but i'd be expecting something big to go wrong every time I drove it.. lol

Ok thanks 👍

Both engines are 6 cylinder and both M54 so don’t think there will be much in it re weight.

As for driveshafts etc will have to find out if they were uprated for the 330 then. Hope there the same otherwise it will be a lot of work 😂

Driveshafts are 100% uprated as the 330i/330d ones are the same.
