N52 Swap Discussion

Yes, it's important to do it right. If I lived in Cali, I would've had to learn what you are talking about. I would try to talk with a 'referee' ahead of time if possible.

I mounted my OBD under the steering wheel on the kick panel. In hindsight, it should be in or near the glove box so the cable doesn't have to reach across everything if you want to place the laptop on the passenger seat.

Do you happen to have a picture of your set up? Thanks!

It's not much, but here is something for you all. I printed this and slapped it up in the garage when I was sorting things.

The WDS and images for the IVM require squinting and second guessing. This makes it simple, at least for my configuration.

Anywhere I can, I want to add clarity for the next guy.

Hello again! Feeling a new spark of motivation with all these new developments I keep hearing about. Finally started pulling the trigger on some parts: IVM, z4 pedal, and engine arms.

Hoping to sell my S52 car shortly and roll the slicktop into the middle of the shop for some amateur rust repair before I start getting into the motor.

Loving all the progress in the new sub!

That's good to know. I must have missed it somehow if it was mentioned here. I spent most of my morning reading through all 53 pages / 791 posts on this thread. I've tried numerous times before to read through all of it but never did until today. Now that I have an N52 sitting in my garage, I'm a bit more motivated to read thoroughly. There's a few posts specific to wiring, but it was mentioned it was trivial in comparison to mocking up the oil pan and arms.




LOL that would be hilarious if that happened here. Typically for engine swaps in California they can either be dirty smogged or legitimately done through a BAR Referee. From what I read, they go through your swap with a fine tooth comb, looking for anything out of place, non-OEM, aftermarket, non CARB approved items. All emissions related equipment must be fully functional.

On top of the emissions portion, they require that the DME be verified by a BMW dealership to confirm nothing has been altered. I'm reading some will waive the EWS delete, as they understand it is not emissions related. This is copy from another thread on here: "I received your letter and forwarded it to BAR. They requested that the info be put on a dealer invoice. They want verification that the PCM is for a 1999 BMW M3 CA cert. The BAR would like the dealer to list the Calibration ID (CAL ID) and Calibration verification number (CVN) as well."

Full discussion of here on another thread. I posted the question a few months ago regarding getting a swapped N52/4/5 BAR'd, but no one responded. I'm assuming no one on here has done so yet?

I'm opting to do it correctly, as this would be my daily driver.

This is also my first engine swap, so I have plenty to learn here. I'm grateful for this platform and all that have contributed to the discussion, it's really given me a lot of confidence to try something new.

Pretty sure no one has - the biggest challenge will be all the gas tank related modifications.
