Sourced out a 3.15 210mm out of a large case e34 diff so will probably go with that. Thanks again. Edit: The 210mm Large case was only fitted to the M5 and 540i e34's all the others had the 188mm medium case diff (Just for future reference as i found little info about this online) Yeah, done all that just wanted to know what the original ratios where for the box.

Yeah sorry should have said, its a e34 model. Has the original Auto diff (unsure of ratio) and have now got a getrag 250 in it. Revs i bit on the highway and 1st is pritty much useless. Just would like to know what ratio would suit.

Anybody know the correct diff ratio for a getrag 250 ? from what I understand its ment to be a 3.45

Thanks guys, conversion done. Ended up costing me $400 for a 160mm extension on the gearbox end of my e36 drive shaft I used. Thanks everyone for the help, much appreciated .

Hi guys, Just wanted to ask if any one had experience in extending there drive shafts and what sort of cost was involved. I have a 1991 E34 and i'm currently doing a Auto to Manual conversion on it, the Ds will need to be extended 150mm. What cost should i expect to see? It will most definitely need a new flange as well. Could some one please list an approx cost? Its a M50 and im fitting a Getrag250 behind it. Cheers

Are they still available ? . Can you give me a email at [email protected] if they are. cheers

The head im after is the 885

Bump Can anyone suggest where i might be able to find one?

Any one got a head for a m20b25 in good condition? Or knows of someone who might? Cheers

Hi Guys, was wondering if anyone had a spare M50 Flywheel lying around or could point me in the direction of a nice lightened one. Thanks

Thanks Jacko, gave him a PM and is getting a price for me. Also -Oli- posted above i might need a E30 Drive shaft does anyone know for sure if buying the e30 Drive shaft will be the correct length and bolt pattern to fit straight in ? . Thanks for all the Help !

Could you post a link? Sorry new here and still learning how to navigate the forum Regard Jamie

I believe its a Getrag 260 but heres the numbers One on the back : 260.0.1.0.60.91 On at the front : 260.0.1346.96 Cheers

Hi Guys, Want to do a M50b20 auto to manual conversion, I have a Getrag gearbox and want to know if it will bolt up to my engine. Cheers.

Thanks for clearing that up, will try 95 Ron again to see if I notice any difference in mileage.

I Put $30 91 in it yesterday. Any reason for not using 91 ? Cheers

Hi Guys, Can any of you tell me what type of gas the M50 engines are designed to run on ?. Also the fuel efficiency, if possible. Thanks. 1991 e34 520i, 190k, M50b20
