Run a wire from the reverse light switch to ground and run a wire from the other terminal on the switch to pin 19 on your FRM unit, that's it. your reverse lights and parking sensors should work if the car has been coded correctly.

Looking to do this in the future as well . I purchased my D with intent of doing this!


I've manual swapped a few cars , mostly Audi's and a few jeeps..

I'm in USA so we have no 330D here at all, is it possible for someone to get me the proper gearbox code so I know what to look for when I import one?
Really the hardest part for me is getting my hands on the right gearbox!

[RS DAVE]

You need the pre stop/start box there are 2, you need the one with the starter under the inlet manifold or as you look into the bell housing the starter is at 1 oclock. Try Saxon Motorsport in Hereford UK. depending on the year of your car,there was gearbox x-member change in sept-oct 06. go on Bmw oem.com all info on part numbers are there.

Any significant difference in fuel economy? I'd think it would be a bit better city , possibly worse on the highway

My car is a 2011

Like Iv told others, you need the 330/325 manual diff. 2.35/1 to get the gearing right, that way you get the economy and more relaxed highway rpm.

I've read about needing to change the rear diff , but never really clear on which one.

To be honest this is the first thread I came upon where someone actually finished the swap for a car they drive all the time

Most people swapping these cars are using them for track cars ?

Mine is 100% going to be a daily so keeping the economy is important. But being a manual transmission purist , idk how long I can bear an auto(although it is a good auto box )

Thanks for the info. I'm trying to write up a complete parts list before I start calling eBay stores and shops over the pond

[RS DAVE]

If you don't use the right diff it renders 1st and 2nd gear virtually useless in a road car, also people on other threads saying the cars don't need coding and their cars started up without being coded is a load of shit. the DME talks to ALL modules, the auto box the shifter everything, when it doesn't get the communication it wont start.

I am very interested in this conversion myself. I am willing to work with anyone to try and get a group of people together to try and figure out how we can best complete this in the US. Parts are going to be harder to get, more expensive, and limited due to the fact they are all coming from far away. If we work together we can prob make this happen to at least one other car in the US, and Im willing to help because a manual version of this car is basically the perfect car for many of us.

I'm in

I forgot the part number for the trans we need but it's readily available and CHEAP

I'm in NY , and willing to help set something up maybe we can bring a few gearboxes and rear differentials over

[Matchstick]

Freight is what screws us

I previously used orchid euro in PA to bring my Audi TDI 01e over via ocean freight it was pretty reasonable but they've been pretty hard to get a hold of recently

Hi everybody,
I will soon finish the mechanical part of the conversion (gearbox / driveshaft / rear axle).
I started early January and only the weekend.
I still have to wire the clutch switch to the DDE and the CAS and the reverse switch to the FRM.
But there is something I did not understand about the cabling of the EGS (to close it).
I watch on the diy of nick380 https://www.e90post.com/forums/showp...6&postcount=50
But not understood
I specify that I am not replacing the engine wiring because it does not exist for 335d manual.
If RS DAVE can you explain to me how did you do it?
Apart from the clutch switch and the reverse switch, there is nothing else to wire?
Thanks

There is no wiring to modify on the engine all stays as is. just run the wire from the clutch switch to pin 50 on the dde. there are 2 pin 50's the one with the curly wire is an injector wire you need the other one in the other plug.

[professorJ]

Thank you for these clarifications RS DAVE.
I think to end this week.
A lot of work without a lift.

When you say Prestop / start box
What is it that you speak of the
Like the Starter ?
Is there a photo or a link
You can provide ?
Found someone in the UK who will sell me the most all the parts I need
Did you take any photos of your swap?

Start stop is a popular feature in Europe and now in the USA where vehicles turn off when the come to a stop and automatically restart when you press the accelerator or releases the brakes

I'm still looking for parts , but haven't driven my 335d all winter . Daily driving a southbend stage 3 endurance in my allroad ... it's fun ..

On that note , what clutch does everyone use/ plan on using. My 335d is a daily and I probably won't be doing anything crazy to it . Would prefer close to stock clutch as possible

Use a standard 330d clutch and dual mass flywheel, we converted my mates car a couple of months ago, he insisted on a 4 paddle clutch and solid 1 peace flywheel, it is fucking horrendous in sound and in use. race car shit doesn't work in road cars...

[professorJ]

I also used a 330d stock clutch and a dual mass flywheel flywheel.
The engine gives about 340hp, no waving or shaking.
You can use the Sachs Performance clutch if you drive harder.

Good to know , I figured the stock unit would be fine , this is all great valuable info!
Got some other shit going on in my life right now so not actively looking for manual parts but if it works out , it works out
I mean if someone has a gearbox and willing to work with me on shipping to USA that's a different story..

Hey i was wondering what websites you got every part from, if you can link em that'd be nice, thanks

I just collected the parts from different places, the clutch and flywheel i bought new. you can try Quarry motors in Sheffield England, they specialise in recycling BMW parts.

Currently looking for a donor wagon and 335d to do this project. Found a used 330d transmission here in the US and bought.

Questions:

1. Is there a wiring list available that specifies exactly which wires to change or add? Or is it only the ones listed here?

2. Which driveshaft to use?

3. If I send out the 335d diff to get it customized will it work? I would turn it into LSD if possible.

4. Contact info for the coding guy?

5. Would it be easier to start with a RWD car instead of AWD? Or doesn’t matter?

6. Any other tips or things to watch out for?

Note: I have previously built an E39 M5 wagon and currently still own an E46 M3 wagon. This is my next project with the M57 modified with big turbos etc. 😃
