N54 swap

[Z4-LV]

Hi community,
Who has engine n54 swap experience to e85 3.0si?
I own 2008 bmw e85 3.0si and recently bought n54 engine with all coolers, fan,ecu and transmission. Mechanical part I will do my self but my main concern is electronic

Sorry for my bad English.

I’m not aware of anyone that has done it on here. Would love to hear how you get on!!!!

Engine with transmission swap doesn't looks difficult but to integrate n54 dme msd81 will be challenging. Right now I'm renewing o-rings and gaskets on new engine and swap planned for end of January.

Is the N52 broken?

Why would you want to swap them over?

I’d guess because of the extra power the n54 produces? :?

Extra power

You might be getting confused with the pre-facelift M54 engine (as I was), whereas the N54 is the twin-turbo engine engine out of the E89 35i/Si.

I'm planning to start swapping at begining of March, so far waiting for reply and signatures from Transport Administration. I did project for this rebuild, I want to keep my zed road legal

 

[Z4-LV]

If everything goes well I will have a lot of pictures in March

Nice bit of engineering that

So is the N54 lump in situ now?

Awesome project! Out of curiosity, where are you located since you say you can have it street legal?
For the DME wiring, maybe you already know it, but check newtis.info and bimmercat.com, the first one has the repair instructions and wiring diagrams and the second one it's the online catalogue to se which parts are compatible with which model. It's what I used to gather infor for my swap (one a lot easier than yours, from M54B25 to M54B30).
Keep us updated!
