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.

I can help you out with all your manual transmission, clutch, flywheel, intake and exhaust manifold issues.
BMW ZF gs6-37dz is a good option with a single mass flywheel, 765 PP and a organic clutch. Will never break and you have a 6spd for top speed and economics

It sounds like you're combo of OM605 + 716.654 with Sprinter solid flywheel & clutch is an excellent start! Ancillaries like throw out bearing, linkages & such may have to be made for it but that should be easy for you to do or hire out.
Your W201 was a manual to begin with, right?
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?
I have a 265/6 and I'm looking for cheap clutch options so I test fitted a Ford 10-spline clutch disc & amazingly it fit the input shaft splines perfectly.
That could open up a world of dirt cheap performance clutches and then maybe a OM605 + Getrag Cosworth 5-speed would make more sense.
Anyone ever put a Ford clutch on a BMW before?!

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.

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.

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?

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.

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.

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.
(01-16-2015, 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

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

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.

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.

Have to measure it but I still don't think it will work.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.

- 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.

It's a good point. But see it this way. First of all the input shaft ends like 15-20mm before the edge of the bellhouse. Then you'll need a 10mm adapter plate that make it 30mm from the edge of the bellhouse edge and 45mm from the crank. The single mass flywheel is about 10mm thick (thin) so you are still 35mm off.
And you have to custom make a flywheel instead of just machining one to spec. And if you do custom make a FW you can make it thick enough to work but those are already available on eBay for the Sprinter van. How much they protrude I have no idea but it might be something to work with if not going for the easy and proven way

Blingfactory might have you covered there. I've got no idea why they made a FW so thick without adding a dual mass pilot. I'll have to compare the next (50th) time I pull my flywheel off.

(01-14-2015, 02:34 PM)F.R.A.S 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.
/ F
the people ive talked to, with 1000hp and dragracing says the 6speed is weaker than the 5speed from the 530 bmw,
dont know the number of the gearbox, but the diameter of the ingoing "shaft" is as large as the 53dz..
strenght
525 5speed
530 6speed
530 5speed.
he went throu three (3!) 6speed 53dz untill he swapped to the 530 fivespeed, and now its the driveshafts, cardanshafts and everything else that doesnt hold up
, the width of the drag tires about 2/3 of the car width.but for a normal diesel the 6speed will probably hold up
