Motor Swap 323ci m52 to m54(330ci) 01

nice job. Makes me want to do an engine swap.

Raymond, this forum (as great as it is) needs more DIY people like yourself, that although told it would be a PITA/ would not work/ too complex, just went out to do it ANYWAYS, and succeed while proving some A$Sumptions to be incorrect.

Excellent work!!!

damn wish i saw this sooner, i was brampton all last week visiting my parents and friends,, i have EDIABAS setup on my laptop, maybe it could have helped with finding your leaks or any other fault codes,. anyhow great job, let me know if you go to any meets in brampton, (guys are lazy in windsor) i should be in the GTA closer to christmas week.


thanks

Awesome job!!!

haha engine swaps are always fun...but they are even better when dont need to drive the car!

interesting - I have read over and over that the intake volume on the 330 intake is greater than the 2.5 intakes...they are different part numbers - when comparing the m54b30 and m54b25

yeah they are not EXACTLY the same...But so close that i used the M54b30 intake boot on the M52Tu25 intake manifold...beside each other they are very close in size... it is only the MAF section which is larger but not the actual throttle body.. i would suspect that this would allow for greater air flow but not by a marginal amount...

Again, I have a M54b30 and an m54b25 sitting here and I have examined the intakes and throttle bodies - i agree that looking at the intakes there does not seem to be a difference...but the TB's are different sizes

AND like you mentioned, the intake tubes from the MAF to the TB are very different (as are the MAF's)

Which injectors are you running? If using the 323 injectors, are you starving the motor?? Running it lean? What color are the injectors on the 323?


btw - I am not questioning your efforts - I am genuinly interested as I have the spare M54b25 motor sitting here and would love to find a dead 323 or 328 or 325 in swap this motor in for my daughter who will be driving in a few months.

does anyone know how much a 323 or 328 with a dead motor would cost? Needs to have clean body and interior...I can fix the rest

ah dont worry im glad your looking into doing the swap your self! well because of vacuum leak i couldn't really tell if switching the injectors made a difference... from what i remember the M52 has black and the M54 blue? Id imagine that the blues have a bit higher flow rating although im sure the stock ones could handle the displacement increase...Up here in canada your lookin at around $5000CND if that helps...I noticed your from Washington, DC. Nice place my friend goes to school around there so I took a couple days off and drove down...only bad part are the roads downtown washington holy crap my slammed vw passat didnt like it very much...gl with your swap though let me know if you need anything else...

I just finished (well, I have some more wiring to wrap up) a swap in my wagon. I removed the m54b25/auto and installed a m54b30/6spd with supercharger. This was after swapping the 3.0L in my sedan with a built 3.0L for stage III SC. I built the 3.0L stage III motor and I enjoyed every minute of it

Hey you wanna sell that m54/b25 motor you just removed from that one car to upgrade to the b30?

did you also retrofit the drive by wire?

I was under the impression that the 2.3 and the 2.8 were "matching" and the 2.5 and the 3.0 were "matching" in the sense of swappability. When motor parts and exhausts are sold, the 2.3 and 2.8 are always the same parts and the 2.5 and 3.0 are the same parts. If I'm wrong then glad it works but I was thinking it wouldn't.

yes I would - it is a 2.5 and I have the 5spd auto still attached to it

Pm me a price for just the motor minus electronics/intake manifold/throttle body
Im going to attempt the same swap raymond did in my father 323i(he blew his motor up it shad 180k on it blew a head gasket and warped the head/block)

This sounds like an awesome swap. I have a couple of questions:

1. So as long as you use the m52tub25 intake manifold everything else is plug and play? As in you did not have to make any customer modifications to either any electrical connections? Exhaust? Drive shaft, mounts, anything, etc? or was is just as if you were swapping a m52tub25 back into it?

2. Do you know if the 323 transmissions fits the m54?

3. Did you do a dyno to see what you were getting out of the motor with the m52 intake and dme? I have Beltronics FX2 so if you want to get an idea let me know.

4. Finally, I am in the GTA also and I am just wondering how you found the engine? What are some specific places I can start calling?

I'm trying to do this swap as well.... but from 325i to 330i

My cousine has a 323i (one of the last ones in production) and I have a 330i zhp. I feel like the difference is pretty immense... But I am looking to get rid of my engine and buying a S54. I would offer my M54 but it has 106,000 miles on it. It does get 31 mpg on highway still I don't know how.

i did a motorswap on my 325ci to a 330 engine. then did a stage 2 supercharger on it from technik.

the DME was a ***** to reprogram.
