Output flange-how far does it move??

[MikeDE]

Dunno if anyone has ever measured but, when going from M42 to M5x, given the swap is done using the same trans, how far back does the transmission output flange move?? I ask b/c i'm planning an m52 swap with an M42 car BUT, and it's a big BUT, i'm using a g240 out of an M40. It's output flange is nearly flat against the transmission case, whereas the M42 G240's is set out a good 2" further(edit: read below, more like 1").

So, with an m50 + M42/g240(long output flange), one can use the E36 325i driveshaft. Now with m50 + M40 G240(flush/short output flange), which driveshaft?? Is it possible to use the e36 325i DEPENDING on how much shorter the M40/g240 flange is, don't want too much spline showing on the e36 325i driveshaft.

OR I still have a fresh M42/g240 driveshaft lying around, perhaps between the trans being shifted rearwards AND the shorter flange, it might work??

Anybody have any ideas?? The US never got the m40(lucky you), so matybe if anyone knows which driveshaft is an inch or two longer than the e36 325i d/s and will mate to an M42 flange, that's be great......help.

Thanks

EDIT-BTW before you ask 'why use a g240?!', because the shift feel is perfect, it's sealed quite well, and I can keep my freshly sealed/bushing'd 4.10.

I think the 325 driveshaft shkuld still work.

BTW g240 POWER!

Blackhawk, I had a brainfart before. The sliding section is irrelevant. Why, you ask??

I just butted my g250 and m40/g240 against the wall to see how much of a length difference there is. I found that the g250 is exactly 1" longer. Soooo, the e36 325i d/s will be too short running the m52 w/ the m40/g240(it's fine for an m42/g240 with the longer flange but mine is in the junkpile).

I need a D/S that's 1" longer than the E36 325i d/s at the transmission side to run my m40/g240.

Anyone????

Did you mean e30 325i or e36 325i d/s?? And yeah, g240 power, my shift feel is so sweet in the m42 Touring at the moment, I want the same with the m52.


Jsst found this:

The one with the new center bearing is the early e30 325 5spd driveshaft. The other is a 92 e36 5spd drive shaft

Sooo...if the E36 slides on the front section, then I should be able to use it? Or will theyre be too much spline showing/not enough spline-contact??
Right??
