I have a NFL 520i in which i swapped a M54B30. After some struggles all is running fine now.
I have kept the original tranny, a Getrag S5D 250G, as it had shorter ratios.
The question is: How much can I abuse this tranny without breaking it? I know it is allegedly rated at 250 Nm, but I am also sure it can withstand way more.
I have read mixed opinions on this, so I would prefer an opinion from somebody who is using this tranny.
Do any of you guys run this tranny with higher power and torque outputs than mine?
On the long run, I plan other upgrades as well:
CDV
SMF conversion + clutch upgrade (still in doubts, will post another topic on that)
Quaife LSD
Motor re-building, and changing to Schrick camshafts, and maybe forged pistons
Supercharger
Custom Exhaust headers
The thing is, after all is done, I should be at around 360/400 hp with 400/430 Nm of torque.
Can my tranny take that without problems? When should I consider upgrading it, and what would be a recommended swap?
I would prefer to keep this tranny for the short ratios. I can get a good used tranny for around 120/250$ depending on the model. So if you have an alternative that has equal short ratios, but can withstand more than my current setup, please let me know.
My understanding is that 250g transmission is garbage and won't handle that kind of power. Either go with the 320z (same as 530i manual, e36 M3 manual, Z3M S54 5-speed, etc.) or the 420g (e36 M3 EVO, e46 M3, etc.) 6-speed. The 320z is a wonderful transmission and is very smooth and has roughly the same ratios as the 6-speed from gears 1-5. Another option is the GS6-37BZ 6-speed from the e60 530i, but it requires a custom transmission crossmember to be made, while the 420g can use the 540i mount. Check out my 530i/6 build thread in my signature for more information on that if you want.

Yes, the 420G is a brawny gearbox, and is used on the E39 540i, as well as the E39 M5.

Just to confirm:
I found this gearbox here locally:
From what I googled, it should be the zf 320z, right?

Another quick question:
Driveshaft:
Is it the same for the 2.0 m52 as for the 3.0 m54 or do I also need to change that??

I have got the 520i (manual gearbox) diff, 3.46 ratio:
So if i swap the gearbox for the zf 320z, can i keep the drive shaft and diff? (I will anyhow change the diff to a quaife lsd this winter, but i mean until then)

Considering it doesn't list any 528i or 530i, I'm guessing no. The reason is the input flange on the diff is smaller on the smaller engine cars, so the cv joint from the 528i/530i driveshaft won't mate to it. If you tried to use a 520i driveshaft, the output flange on the 320z is too big for it, so you really need to match the diff to the transmission and use the matching driveshaft.

If you were in the US, I could have sold you my 528i driveshaft and diff, but too heavy to ship international.

Got it! So i need to look for a 528i/530i diff.
My guess would be no, but still a chance as they share the gearbox:
What about an e36 328i or e46 330i driveshaft? Would it also be a match?
+ LE:
Is the driveshaft different in the estate cars?

E36 has a totally different type of diff flange. It has to be e39 528i/530i. Touring 528it/530it (if ZF 320z) should have the same diff and driveshaft as sedans
