Default 2001 325iT S54 swap

My first thread here and one of only a few posts even though I’ve been a member for a while now reading up on info related to the E36 M3. I have had my 2001 5mt E46 touring for 10 years now and it has been dead reliable and quite a bit of fun to drive. It seems like the next step for this car is a change in attitude with bit more power via a S54 swap.

As of last week I have my local dismantler looking for a good 6spd donor M3 and have been diving into the forums to learn from those who have done this in the past. Thanks to Kaiv, Redshift and Jared’s write-up’s on this forum I have been able to gather a great deal of info and start a solid project list.

The mechanical side of this swap seems dead easy but I do have a few questions to make sure I’m on the right track:

A) Rear swap all M3 and keep the Eibach/Bilstein’s from the 325. There is reference to the 325 wheel speed sensors being too long for the M3 tone rings – is this accurate?

B) Leave the 325 front suspension understanding the downside being smaller brakes and wheel bearings as well as a slight F/R bias change with the M3 rear brakes. Depending on your source, the difference in the weight between the S54 and M54 is ~60 lbs so I don’t think the handling would be too upset.

I am contemplating keeping the current front suspension because I have less than 2k miles on fresh ZHP control arms/bushings, wheel bearings, pads/rotors and Eibach/Bilstein’s. I’d hate to throw away the $$$ but if the M3 front is the way to go then I will make it happen. The stock M3 front swaybar drops in place of the 325 piece so I can keep the balance decent with the rear swap.

C) Keep the 325 Mk60 ABS/DSC. Will this work if (in the future) I swap over the M3 front suspension/brakes? I also see mention of the need to swap to the M3 DSC if you want TPMS functionality but the 325 does not have it and I don’t need it (maybe this is an issue with the light being illuminated in the M3 cluster?).


Now the wiring is where I really get into trouble and is an area where I have very little experience (I had Markert build my E30 M52 swap harness). From what I have gathered the wiring is not too involved…but I think some of you guys are being modest when you say this... Where does one even begin to comprehend the maze of the WDS?

Here is what I have so far:

- Extend washer pump wiring to drug bin - easy
- M3 aux water pump needs one wire to IHKA and one to ground – what pin on IHKA?
- Move several pins in the E-box – which pins? – this is where I get lost…
- Add wires for ZKE or IKE – needed?

I understand that the coding for the swap will need done by someone with the skills to sync DME, IKE, EWS and LCM to make all systems happy. Is this coding done prior to starting the swap or after? It seems that those who have done the swap have started it prior to coding? If it matters, I am planning to just swap the DME and IKE, not install the “sport” button and delete the SAP.

Thanks for reading and apologies for the brain dump. Hopefully some of the above makes reasonable sense and I look forward to any information you can share to help me get this project off on the right track.

If you are still following along here are a couple of pics:

Hi Nick - thanks for the reply. I checked out your journal thread and love the Steel Gray/Tanin combo, what a great find.

I also see you have sourced a donor so the fun will begin soon. Were you able to find your donor locally? Salvage M3's are not quite as plentiful in the midwest from my searching so far. I look forward to following your progress.

Thanks for all the kind words. This should be fun once all the pieces fall into place. Still hunting for more wiring info.

I have owned the car for 10 years now and have enjoyed every minute.


leegf - if you have not seen it, there is a "tourings for sale thread" over on E46Fanatics in the touring forum that gets some regular postings of cars people find FS around the US. Might help your search.

Wagon looks awesome! I have a 323it for my daily. I’d love to do the swap but I need to do it in the e36 first haha.
