All....great thread and thank you for the DIY. Gives me hope.

I have been looking for a pristine 325it Manual (sport, cold weather, premium) for 4 months and have yet to find it. I'm thinking about buying an 2002 325it auto and doing the swap.

Two questions for those who have done the swap.

A) Do you wish you had put in a 6 speed? I seem to remember reading that the bolting pattern is different (maybe that's why you did the 5spd???). Just thought it would be nice to have 6th gear since I do a lot of highway driving.

B) Any issues passing emissions testing (I live in MA, which I think is second only to CA for its strict emissions standards)

Any advice is appreciated...Thanks in advance!

^ went with 5 speed cause of the cost involved. Yes sometimes I do wish that went with a 6 speed instead. At the moment I get a little more than 300 miles to a tank. With my heavy foot I don't consider it to be to bad.

As far as emissions go, if you get the correct coding I don't see why you wouldn't pass.

I have the 6 from the factory and it's great, but don't regret the 5 too much. Remember the 6th is just an overdrive, and some report getting better mileage riding on the hwy in 5th.
And shifting on up to 5th is the same in both cars. A little quieter in 6th than 5th at cruising speed, but once in a while I'll forget to shift to 6th and only notice when I glance at the tach and see the rpm's a little higher than I'm used to.
And when I want to pull up to 127mph I use 5th exclusively. It gets me there fast, and 6th takes so long I've never actually seen that speed except in 5th.



Love the driving out in West Tx on I-10 or I-20 where the limit is 80 mph!

What I have learned from doing the swap. If you have a ZF auto trans you need to jump the 1 pin-out to 5 pin-out. It will start right up. I am not running any of the clutch pedal sensors, only the auto brake light sensor and everything works including cruise control. Obviously if you push the clutch in it will not cancel the cruise control. You do not need the complete 2 piece driveshaft. I used the front section from the transmission to the center mount. Not sure if you are able to just buy the front section separate.
I know it has been said before but make sure you address the starter locator pin. Either cut off the pin, file it down, clean the corrosion, just make sure it goes on bell housing easily. I had a hell of a time getting the starter to align correctly. I didn't notice it until I had the transmission and everything back together and went to start it and the started sounded like it was going to fall apart. Sure enough the starter wasn't aligned and lets just say that added a good 3-5 hours to fix it. I didn't drop the trans again but looking back it probably would of saved some time to just drop it again and fix it. What a pain. Hope this helps a few people.
I like the 5-speed with the 3.46 diff which is stock on my wagon. I just don't like the 3500+ rpms @ 75 mph in 5th on the highway.

Hey Neil.

Great job on ur swap. I recently did a swap on my 01 325ci. I used a 03 330ci motor and manual trans. i also used the key, ignition switch, wiring harness and and the box that goes to it from the donor car, (dont know what its called, just knows it goes under the dash by the pedals. My question to u is... do i still need to have it coded? The dsc light on and the gear selection led on the cluster has a gear with an exclamation mark in it. My mechanic who did the swap said its from the car needing an alignment. I talked to a place called the Bimmer Workshop here in Houston, TX they said something is not hooked up or wired correctly. I tried programming the key to unlock the doors several times and it never worked. the original key still does. I was also wondering about the two red wires located by the DME in ur swap write up. What are those wires for? I dont recall reading about them, unless I missed it. Please feel free call or message me back when u have a sec. 8159147389.

Thanks Bud
Monty

Wait what? Seems like you did extra work for nothing, could of used the same key ignition. You would have to code the dme to the m54b30 and still code the cluster and everything else. You need gt1 or progman, also ncs expert could maybe work.

Does anyone have a part# for a plug that would cover where the shifter cable went after doing the 5-spd swap? I get a lot of heat coming out of that open hole now. I've got an arrow pointing to the hole in question.

I used aluminum duck work tape. You can find it at lowes. Works great just clean the area good first.

One goes to whatever color wire in the directions, then you can put the other to a wire that gets power with the ignition and they should work.

Ugh. I've been searching for a while now.

I've got all the parts for my swap in my garage, but I still need to gather up the pins and plugs that I'll need for the clutch and reverse switches.

http://realoem.com/bmw/partgrp.do?mo...28&hg=61&fg=15

I know I need at least 2 pins, and one plug for the reverse sensor on the transmission. Does anyone have any idea which part #'s I need? I remember seeing a post where they discussed which parts to use, but I can't find it, as I saw the post probably a year ago.

Thanks in advance! I'm excited to get started on my touring .

Quick question on this can I get away with programming the car with PAsoft? there's several options ive seen in there regarding manual vs auto.
