M20 Getrag 240 on M20B25?

7 posts in this topic

Hey guys,

So I have pieced together a manual transmission kit for my 325i E30 however I could only get my hands on a Getrag 240 as well as a 320i driveshaft to go with it. Doing some research online people are saying that the 240 box is not "strong" enough for the B25 engine??, just wanted to get your opinions on the whole setup, and if it's a better idea to get a Getrag 260 box and the 325i driveshaft. 

Cheers,

Vinu

unless you're racing it or abusing the sh*t out of it, it will be fine.

Agree with Polley, the 240 will be fine for normal use.

Hi........jacking thread! 

I'm doing similar set up but with m52. Is the 320 drive shaft out of a manual or auto  or doesn't it matter?

Manual 320i has a longer front section than the auto. Rear half is the same

Manual 325i front section is from memory 37mm shorter than 320i

Hey, 

Yea like Grant said you have to use the manual drive shaft as is quite a bit longer than the auto driveshaft, as the auto gearbox is a lot longer than either of the manual boxes if your using the 240 box you'll have to use the 320i driveshaft, and if your using the 260 box believe you will need a 325i driveshaft. this is due to the 260 box being slightly longer than the 240 box.  

PS: Anyone know where I can get a sachs clutch kit in NZ for a decent price?

Aha! Understood. Much appreciated! I'll get looking for a manual 320 one!
