That's unfortunate to hear After researching it seemed the price point they were offering seemed considerably low considering the price of used engines seized or not. Sorry to hear that situation

As of now the car is running perfectly! The previous issues were quickly resolved with replacement of the servomotor, and hpfp sensor replacement.

The journey took about 4 months, including researching, sourcing and labor. Hope you get your Bimmer back to life!

YESSS
I'm glad to hear your car is alive and well again!!

Hi xlugoz

Very happy to hear you managed a successful swap.

This is a long shot - I am in a 2011 E82 135 with a dying/dead N55 that I would like to replace.

I am trying to find out if 2012/2013 E82 135 N55 will fit in the car? See my post on 1Addicts here:

https://www.1addicts.com/forums/show....php?t=1905343

My shop says that it will not be a straight swap and the coding will be too much. Based on your experience, is the coding in these situations a challenge?

Just trying to get a feel for the scale of this task? And if its even viable/possible?

I would happily throw an F Series N55 in to the E82 135 if it was possible?

This guy seemed to pull it off but was short on details:

Thanks in advance.

The swap will be possible but it will definitely be an extensive process, almost as if you are doing a complete engine swap. Your shop is right trying to swap a F series to an E series will cause a lot of headaches and unnecessary labor

It's in your best interest to stick to the same E series N55 and PWG. You'll require a lot of electronic replacements. If power output is your concern, an E series N54 would almost work better.

My swap did not require any coding at all it was a straight drop in and ran, no coding required, ZF8 '16 M235i to ZF8 '14 435i, F chassis, EWG.

Not the best outcome but definitely within my budget, caught it at 50k miles, basically going to be a drop in play, a bit of coding might be needed for it to run properly, nonetheless I still intend to swap the oil pan for a s55 oil setup, baffle, pickup and secondary pump.

I do not want to go through this again!

Will keep this thread updated.

Nice work! Thanks for confirming that the N55 from the M235i dropped in to a 435i did not require any coding.

That may be an option I am looking at for the 335i.

Quick question I recently blew my 2013 F30 n55 engine and was wondering if you know if I have to stick to a pneumatic wastegate, or can install an engine with an electronic wastegate thanks .

It's a million times easier to stay pwg.. otherwise you're not just swapping a motor.. the pwg setup has things the ewg setup does not
.. so you'd need a new harness the correct vacuum setup, dme etc etc and a ton of coding and stuff. Unless you can get a very cheap donor setup it's cheaper to get a new car lol

The engine itself (block assembly, cylinder head) can be used, but you will need to use your original DME (on the intake manifold), and a PWG turbo, and associated components.

Another thing to look out for if you use the new engines fueling system is EU5 vs EU6 injectors.

Hi,
did you tried to research possible M2 N55 fitment? I'm in similar position as you were, engine on my m135i (hatchback version of m235i) is blown and I'm trying to research if M2 N55 engine would be easy preplacement. It is EWG for EWG. As far as I searched, only differences are internals (pistons heads, bearings, oil) and oil pan. But it would be great to hear form someone else to confirm it.
Thanks.

Note the oil pump e vs f is not interchangable which can be overlooked when swapping accessories.

Thanks for pointing that out, but my car is also F series (F20) so it should be fine.
