Manual Trans Conversion?

Yes and no

I know there has been some talk about auto options here but as long as that project isn't dead in the other thread I am sticking with discussing the manual options. As stated, getting an auto to communicate with our car is opening another can of worms.....

As Tiago mentioned, there are manual gearboxes from other models that should bolt up to our cars, but I wouldn't consider them a direct fit. Most BMW trans bellhousings are supposedly the same pattern, but the issue would be the flywheel/clutch. From what I have found the 330D crank bolt pattern is definitely different than our cars. Not sure about the starter gear/diameter on top of that. So that means a simple solution is out and a custom flywheel/clutch is in order. I kind of like that idea because we can configure any clutch we want but it makes things more complicated (below).

I think I've been able to gather all the dimensions up to make a bellhousing adapter. There are a few custom racing BMW bellhousing adapters out there for different Tremecs but not the TR6060 (T56 Magnum). So that would mean buying a more expensive custom BMW bellhousing and then machining it, kind of defeats the purpose. Instead I would opt to just make an adapter to a Ford Mustang or Camaro pattern (with factory TR6060). The next question is which of the 2? I wanted to get approximate locations of the shifters and mounts on both and see if one would be closer than the other. There are TR6060 shifter relocation kits out there so if either wasn't feasible, they could be relocated to fit. Or just find a steal on either of these transmissions and take a chance.

I also was after some important measurements from our cars. Like crank flange face in relation to bellhousing face. Also bellhousing face in relation to manual shifter location and driveshaft. And of course crank flange bolt pattern. These are all necessary to layout the spacing in CAD and draw up a flywheel/clutch assembly (and not rip apart my car and have it sitting for months). The banned one may be able to help on his next trans pull, I would love to get my hands on one of our flywheels. If done right, all of this would allow parts to be designed and machined ahead of time without disassembly. I have a few other projects I'm trying to wrap up (intercooler and cold air intake) so that's as far as I got.

Dave,

Any updates on this? I have begun pestering Bob at BPC about it too. I'll try to get the autobox working right first, but definitely interested in a BMW six speed manual.

TIA!

Nah, nothing at the moment. Too many projects going on

I am hoping our coding gurus figure out our auto soon, looks like they are getting close. If we can get access to modify that it should suffice for me. BPC may be able to help in the meantime if you absolutely want a manual in your D.....

Its done and even has launch control.

I found a shop at my country that supports racing teams and makes from scratch custom gear sets for gearboxes and diffs.

After seing the vid, i'm now really considering the 530d 6mt gearbox and parts retrofit with a custom gearing to match the current AT ratio.

For the 530d, sachs racing has a clutch kit for +780nm and even has a dmf with a special multiple rated springs design to provide smoother take offs with organic compounds.

^^^ OH MAN That is great news! I want this.

I hope someone can complete this and put a price tag on a swap kit soon!

dominican · 06-05-2016, 08:57 PM

Color me interested.

shnaggs · 06-12-2016, 06:15 AM

I might, it depends on how poor this swap would make me.

I would jump on board for sure if it works

Bob@BPC · 06-12-2016, 10:09 PM

How many would be interested in this swap? We've done a manual swap already in a E90 N52 and at our cost it was around $1500 - $1700 in parts.

For real? If I don't have to row 3 gears before my tires roll out of a stop light I could be interested for sure but it'd have to be after I'm out of my CPO

natefank · 06-12-2016, 11:56 PM

Hey Bob, how bad is the install on one of those kits? I'm all the way on the west coast, but I am very interested in the swap

I'm in! I want to keep as much as possible stock otherwise, including fuel mapping and stability control etc.

I'm interested. Do you have any details?

It was really straight forward on the N52, got parts from a wreaked 328i 6 speed, swapped over, cut a few wires to make the starter work and re-coded the car.

As stated above, this worked great on a N52, im not sure if it will be as smooth on the M57. We would need a car here at the shop to build and test a kit on before we could even think about releasing to the masses.

335duff · 06-13-2016, 11:15 AM

For an otherwise stock engine system, would clutch or internals need to be upgraded? Also, where do we get the transmissions from? 330d was never sold in usa unless I am mistaken.

iaknown · 06-13-2016, 06:01 PM

Does anyone know if the 535D flywheel will fit our engines? Clutch/flywheel options were one of the main reasons I stopped pursuing this. Sure a trans can be bolted up and I understand there's a few clutch options now. But to get a clutch that doesn't chatter and/or make a bunch of noise is another story. I'm wondering what that dmf can handle....

BB_cuda · 06-13-2016, 07:50 PM

I bet the bodacious guy knows. Perhaps you might be able to talk him into borrowing a flywheel for measurements. Recall he had bought 2 M57 engines.

natefank · 07-02-2016, 12:33 PM

I just wanna bump this back up and see if Bob at BPC has made any progress on this for us

Grazy_87 · 07-03-2016, 11:52 AM

Will be starting my build this september, will be using 330d manual trans for the conversion.

335duff · 07-03-2016, 01:49 PM

Please do keep us in the loop! I think there are lots here that would go for the conversion tomorrow if we had some bread crumbs to follow.
