As the title suggests i'm interested in dropping a 3 litre straight 6 from an E46 330ci into my car.. I've had this idea ever since seeing an E46 compact with an m3 engine on bmw syndikat..
Just wondering as i've never taken much interest in engine transplants etc what would be involved?
Obviously I would need to upgrade my brakes, I've already got coilovers and new re-inforced top mounts so suspension should be ok..
Is it just engine/gearbox/ECU that are transplanted??
Any help or advice would be HUGELY appreciated!
I think this would be a cheaper alternative to buying a 04 or 05 325ci/330ci as I was planning to do next year..
A lot is involved
Engine and gearbox will need to be changed, the ecu, wiring, might need to be coded in if your not changing ignition barrel.
then you would need to change the full exhaust from the manifold backwards as the 3litre is a 6 cylinder and has twin exhaust pipes to the back.
Brakes also like you mentioned
would be cheaper to buy a 2001 330ci i would imagine
Next question on this subject now that i've had most of my questions answered..
Would I have to re-inforce my subframe/chassis to fit a 3 litre lump?
Also would any work need to be done to the engine bay? And finally would I need to have custom engine mounts made?
Hopefully someone knows these things because I can't find anything close to answering my questions online anywhere!!
