Driveshaft woes.

[i3uller]

I have an 87 325is and am swapping in the m50 attached to an e36 5 speed. Here is a picture of what is going on. Any suggestions?

E30 or 36 driveshaft? If 250 transmission, you must use E30 M3 driveshaft.

[i3uller]

I'm using the stock driveshaft on my 87 325is with an e36 5 speed tranny. Non ///m i beleive.

[Stu]

That combo doesn't work. You need an E30 M3 driveshaft. Stock driveshaft can only be retained if you use the stock trans

E30 trans, E30 diff……………………..E30 driveshaft

E36 Getrag trans, E30 diff……………E30 driveshaft

E36 ZF trans, E30 diff…………………E30M3 driveshaft

E36 Euro 6-sp trans, E30 diff…..…….Shortened E30M3 or E36M3 driveshaft

Bueller, you are using the correct driveshaft, my mistake. I confused the ZF and 250 gearboxes. What about the center section, can it be adjusted further?

[i3uller]

I'm not sure. I'm gonna look at it a bit more after doing some more work to get the engine start-able. But I like to hear that I have the correct driveshaft. There has to to be some way to shorten that gap up. What is the ZF tranny anyways?

[86325e]

You can adjust the length a little. Just unscrew that nut deal on the driveshaft some and pull it apart a little. Thats what I did on mine and that closed up the gap fine.

I pulled the centerbearing forward, then if you pull hard enough on the forward part of the driveshaft you can make up the difference. It shouldnt take too much effort to do.

Your ecu will be there before 3.

you just did- get your drive shaft to work?

E36 ZF trans, E30 diff…………………E30M3 driveshaft

E36 Euro 6-sp trans, E30 diff…..…….Shortened E30M3 or E36M3 driveshaft

So my late model E36 M3 trans needs an E30 M3 driveshaft eh? Would it change if I swap in the Z3M roadster diff?

Drive shaft problem = solved. It's a thing of the past. All that is left now is to get the radiator installed, ecu installed, coolant res installed, do the wiring, and bleed all the systems. Almost there.

Nope- you'll still need the m3 driveshaft... its pretty much the same diff (my understanding that is).

Well I just checked today and the E36 M3 driveshaft with my E36 M3 trans and E30 diff all work together. No need to buy an E30 M3 one.
