Om603 with BMW gearbox.
Om603 with BMW gearbox.
Or do I need to get a tranny from a m3 or v8 BMW engine or something? What do you guys think?
Hey guys. The automatic transmission has been dead for a long time now. And I couldn't find a decent Mercedes manual tranny. And it seems the 3rd gear is always the weak link. I thought of fitting an BMW gearbox from a e36 325tds. They're plenty of those available here at a reasonable price. I've seen someone cutting the bell housing and welding on the one from a merc. I don't want to do that. How is an adaptor plate working out? It could be that I need to mill down some surface area of the bell housing but that's okay with me. My car has at the moment about 300hp but I'm thinking of future upgrades to about 400hp.

I've heard good things about the Getrag 265 (dogleg or overdrive).
One major benefit is that it has a removable bellhousing.

'06.5 VW Jetta TDI - 230k
'82 MB 300TD - 116k (motor going to raysorenson)
'81 MB 300TD - 195k (parting out)
'71 Jeep DJ5 - diesel conversion project

Did some research on them. They look good and are often used for old rwd opel's to convert to a newer turbo engine, I see that happen quiet a lot here. They are kinda rare because of this and that makes them expensive. And I still don't think they hold up 300/400 hp. But it's definably an option I keep open.

If you want bulletproof, go for 530d gearbox.
Cutting and welding is almost standard or buy a trans thats already has been modified for benz.
Holset power!
525 tds I a great cheap trans. Almost everyone in Sweden drives that on there superturbo gasoline Volvos.

(12-12-2013, 01:29 AM)Tito I already bought a 717.430 trans for the 603 for a bargain. In the near future i want to upgrade to a 606 engine. And then I have plenty of time to fit a bmw gearbox to it
you will probably be pushing the limits of that gearbox with that 300-400whp you was talking about.
safe numbers ive heard for it lays around 200-250whp, althou it al depends on how you drive, it has survived my om602 7.5mm engine this far, (i have the same gearbox) and the engine puts down around 220whp.

The 400hp will probably be with the 606 engine. I'm not thinking of further upgrading my current engine since it's a n/a engine. So 300 hp is a lot. Have had it up to 2.5 bar
We will see. I spend the whole day mounting it. Tomorrow the finishing touches and it done.
