I'm looking to do a swap on my f30. Does anyone know what type of engines are capable to have a successful swap? Any advice, greatly appreciated.

What engines you have in mind? 2jz or ls swap would be bad ass

Good Luck incorporating the Canbus to control the electronics. But it will all be custom made. Car is too new and way too expensive to start with to have anyone do any swaps. GL OP!

Id say a n55 or try a b58 if you can. Id ask n55rs or some other people who have wanted to do a swap.

[D041987]

N55 or B58 should not be too bad as canbus is already there in the ECU. BUt you will def need to do some wiring/ pin changing and coding/ adaption will need to be done.

Wonder how much it would be to swap to a b58

[BMWtight2me]

Well cost in parts to replace an n20 is about 26k. So I imagine a b58 would be preeetty pricey.

Thats alot id rather just get a LS and swap it and just get a new ecu etc...

[DEMONIC]

It will be better, easier and cheaper to buy 335i or 340i.

Agree id rather just get a 340i id honestly get a 235 or 240.

[Gamb1t]

Are you sentimental about your 328i that you rather transplant another engine instead of just upgrade to a higher spec 3er as others suggested?

What’s about flashing the ecu?

[jmichaelh7]

Well it’s my commuter. I have 117k on it and climbing 60 miles every day. I figure if I found a bmw parting out because it’s totalled and find a motor for about $4k how hard it would be to do it. From what I’ve read the n20 seems pretty reliable however it’s a bmw .

lol just read the whole thread and people are chiming in with grandeous swap i.e. Ls1, 2jz ....don't forget rb26dett. ....lol

Then OP mean, replace the old n20 with a fresh or remanufactured n20?

[Riick]

It will be cheaper and more reliable to trade it in for the car you want with the engine already in it from the factory.

[BunkerJ]

Hey OP, did you know you could buy a Porsche 918 and be quicker than engine swapping your car?

Focusing on your actual question, 2nd reply to the thread hit it on the head. N55 with the associated DME would be your easiest option (leaving the N20 out of it). I'd assume with a similar year, so long as you can get your CAS to accept the DME and sync with it, you'd be fine. I'd be a little more wary of a B58 swap as all components in the chain with CAS would be different and may not accept each other. That'd call for you to pull either the same parts associated with it or at least the same parts that are virginized and then initiate a sync. It definitely won't be fun but if you have the time/money and are really wanting that over a new car or new N20 engine, then go for it.

[jmichaelh7]

Thanks for the input. N55 would be something

Does anyone have a link for instructions on how to perform an engine swap on a n20 with a n20???

If you do the motor swap you still have 117k mi on all of the other parts.

Buy a classic or 30 yr old car and play with it.

Fairly simple actually. Plenty of room too. I've not done it but done many V6TT on my old GTO and FTO V6 which was very tight. Given the room in the F30 and N20 it would be easy.

Disconnect:
Remove trim to reveal rear engine
Under trays and reinforcement plate
Fuel to engine at HPFP
Wiring harness
Bolts of gearbox
Bolts to torque converter (support underneath)
Coolant drain and remove pipes in and out
Drain oil (less weight)
Insert towing eye into hole next to oil cooler housing (you need an old one from E series)
Air pipe to manifold
Intake Manifold
Starter motor
Vacuum pump to brake line

Generally you want everything out of the way then support the engine on a hoist while you undo the nuts on the engine mounts and slowly lift away checking you've not forgotten anything or snagging anything
