(01-13-2015, 02:27 PM)Y444TES Hi all

I'm collecting all my bits together ready to build my om605 w201 and I've done loads of reaserch but it boggles the mind after a bit with all the different set ups people have but I've got a 716.654 6 speed box and a sprinter and conversion kit would this setup work with my om605. As well I have a getrag cosworth box but no clutch setup and no idea what to use and any help would be greatly appreciated thanks

Oh and my om605 has a 7mm pump and hol set hx30.

(01-14-2015, 03:54 AM)raidaru FRAS , I thought GS6-53DZ is better than GS6-37DZ !? is it not?

(01-14-2015, 11:25 AM)F.R.A.S Absolutley, the 53dz is a super strong gearbox but the 37dz is half the money and is still twice as strong as the strongest Mercedes gearbox you can find.

(01-14-2015, 09:37 AM)CRD4x4 Does your Getrag Cosworth gearbox have a removable bellhousing?

I *think* they're the same/similar to the BMW Getrag 265/5 & 265/6 (dogleg & overdrive, respectively). Wouldn't yours bolt up to a 617?

(01-15-2015, 01:33 PM)Duncansport Awesome

Your really putting the fear of god into me about my .430 haha

(01-14-2015, 02:34 PM)F.R.A.S ANY. The Mercedes gearboxes are just pure shit. The only main thing with them is that they fit. Yea or almost... They only fit if you have a dual mass flywheel. People in Sweden witch you should know are going 1000whp with the old BMW miniature 5spd TDS-gearbox rated to 320Nm. The newer 6spd are tougher than that. And they work on all gears. In a Mercedes you have to do 1st, 2nd, 4th, 5th cause 3rd is made of glass.

(01-15-2015, 05:04 PM)Y444TES Thanks for the help lad and them 37DZ boxes are a lot cheap than 53DZ boxes and you have got me thinking now I might just get a bmw box and go down that root

What flywheel would I need for the GS6-37DZ box.

Cheers Sam

(01-15-2015, 05:28 PM)Turbo Well I asked a about torque since the power transfer is a product of angel velocity and torque, if you have high rpm it not that strange it going to be high HP rating, so you say with 1300Nm of torque and slick it will hold together?

so you are making a tremec adaptor, very interesting, for what version of gear box?

(01-15-2015, 05:49 PM)F.R.A.S We always makes it for a singlemass flywheel and always go Sachs 765 PP. That's easy, cheap and durable. Then you can choose organic clutch, 4-point sinter, 6-point sinter, sprung or not etc.

The 53dz will have no issue @ 1300Nm and slicks. The 37dz is weaker but as long as you don't build a large tire dragrace car with 4-link and line-lock you'll be fine.

I don't have any Tremec at hand I'm afraid so the only gearbox I know it will fit is the Ford and Chevy Tremec T56. Maybe the T56 Magnum has the same bellhouse bolt pattern, that would be awesome. And I'm not building an adapter I'm building a complete bellhouse with the right distance for the input shaft and so on...

(01-16-2015, 10:16 AM)Turbo what clutch would you recommend for 1200-1300nm of torque

when do you think you will have a bellhause finished for tremec?

(01-16-2015, 12:20 PM)F.R.A.S 3-disc Tilton.

Tremec bellhouse will be done in two weeks give or take. Have surgery coming up on monday but I'll try to get it done asap.

(01-16-2015, 01:48 PM)Turbo may I ask why you building a bell house for Tremec?

(01-16-2015, 02:26 PM)F.R.A.S It's easy. Swedes are a world minority and for one thing we fabricate and sell here we sell 10-12pc to the US and another 5pc to the rest of the world.

In the US the 53dz gearbox is pretty hard to find and the Tremec are in the dozens. The Tremec is a pretty good gearbox with plenty off upgradeable parts available. It also have a removable bellhouse witch makes it perfect for a custom installation.

(01-16-2015, 01:48 PM)Turbo may I ask why you building a bell house for Tremec?

(01-16-2015, 02:51 PM)Turbo I have thinking many times about a T56 magnum of many reason, and you can buy a cryo hardened that take 1500NM in all gears, but the old t56 like in viper you can not shift fast, and in my case 4 bars of boost does not come back in a blink of an eye, the new t56 magnum shall be much better then the old but how much better?

have you come up with a price on that bell house?

(01-16-2015, 04:42 PM)raidaru brahs, I've been having this thought on my head for some time now, couldn't it be made an adapter plate with the holles for om606 engine and in such a way that the bmw gearbox can be welded directly to the plate without cutting the bellhousing? even if u cut a few places in the bmw bellhousing for puting the screws/strenghtening, but to be a standard adapter plate that u can't go wrong with the welding angles and stuff, I believe it should be possible, and the plate to be as thin as possible but still enough rigid it would be best thing for om606 after the superpump tremec&stuff is a dream for most of us, but a f...ing 5 spd from e39 530d is 400euros and full of them! People are dragracing 1000+nm on this boxes!!! Let's put our minds to work and sort this project out! And also the SMF that has to be machined to take the SACHS 765 PP . And everybody will be happy and burnin tyres, not cracking 3rd gears!!!

(01-16-2015, 05:00 PM)F.R.A.S I don't have the measurements for dual mass flywheels but for single mass this is not possible I'm afraid

The input shaft off the gearbox has to stick out 15mm from the bellhose edge to center in the crank

That's why we weld the gearboxes. Otherwise I would have been drawing an adapter plate a long time ago.

If you make a jig you can weld the gearboxes easy. Just make sure to mill them straight first. And DON'T center on the shaft.

(01-17-2015, 02:40 AM)raidaru Then how about making let's say a 15mm adapter plate and a nice custom thicker flywheel?(even if needs design from scratch) Then you should be able to center the shaft in the custom flywheel. If u sort this thing out for once, then bmw g-box will be like puting a new mb gbox in the car,bolts on! And u can mass produce them afterwards, pretty sure they'll sell well

(01-17-2015, 05:16 AM)F.R.A.S For us it's no business in machining a flywheel but there are dual mass conversions out there for the Sprinter van that people use. Have to measure it but I still don't think it will work.

The newer BMW gearboxes also have short input shafts and the flywheel have to be really thick = heavy if not made off aluminum.

It's a lot easier to weld the gearbox and have a true Plug n Play gearbox

I understand the idea though, just have to be realistic about it and I can't really see how it would work. Sorry mate.

(01-17-2015, 12:53 PM)raidaru It's obvious a standard flywheel be it SMF or DMF won't fit with an adapter plate. As for a thick custom flywheel, there can be made a light design, doesn't need to be a full piece of iron 50kg heavy, u know what I mean. If adapter plate is 20mm, then custom flywheel needs to be 20mm thicker than OEM one. Then u could mass produce the flywheel and adapter plate as a kit working let's say with the SACHS 765 As far as I know the 5spd from 530d e39 is the strongest, and also cheap, @400euros. It's just my opinion that if good design for parts, the rest is piece of cake, and people all @the world would benifit and you'll make some $$ too.

(02-26-2015, 10:10 AM)CRD4x4 Quick noob question off the top of my head:
- if the input shaft on dual mass type transmissions needs to protrude 15mm past their bellhousing in order to center on the 606 crank (as gathered from above), couldn't a solid flywheel be made to bolt up but without a hole in the center, instead having a machined "artifical crank surface" for the input shaft to be centered on?
This way, it seems to me, one could use an adapter plate for the bell-to-block and still have the input shaft reach a surface that'd act as the crank center hole.
As admitted above, I don't have indepth knowledge of this subject so please educate me if I'm way off.
