Getrag 5 Speed to ZF 5 Speed Swap

About to do this swap for my turbo build. Was wondering if this box fits the same as the getrag. Would i need anything else for this to work?

I think I read that you might need a different driveshaft because the Zf has a bigger output flange. Also something about a 4 bolt driveshaft?

Is the ZF you're getting the stock 330 5spd? If so,

Check RealOEM and compare the P/N between the 330 driveshaft and the 325 driveshaft. If the number is the same then it should work. If not then you'll need to source a 330 driveshaft. Shift linkage should be the same (Rebuild this while you're there and replace your CSB and Guibo as well to save yourself a headache down the road)

Good luck.

I already had done so and saw that the ZF driveshaft was slightly longer, but i wanted to double check and make sure if anyone has attempted this before. According to the article sent by iowna330xi, you can remove the getrag output flange and install that on the ZF box. I think im going to go that direction.

If nothing else the Getrag box has shorter internal linkage -- the stock 330 shifter will give you nice short throws on the Getrag box.

When naturally aspirated it's fine, but when going sc or turbo many people prefer the Zf because it is beefier and can handle more torque. Hence why the 330i's and M3's have Zf.

Keep in mind you cant run a 330 drive shaft on a 325 unless you change to a 330 diff. 6 bolt connection to diff instead of 4

Thanks for the tip. Hoping that swapping the output flange will work.

The inference is that Getrag makes shitty gearboxes but in the MB world, they don't. Those boxes last forever and are known to be pretty bulletproof. They also shift awesome. In MBs of course. I'm not buying the 'Getrag is shitty' nonsense. BMW specs the gearboxes anyway. Everybody thinks the GM autos are shitty and the ZFs are better, but that's also nonsense. If the zed F manuals that come in the 330s and M3s are stronger, then that's a function of the BMW spec, not because Getrag somehow manufactures weak or otherwise inferior gearboxes. Blame BMW not Getrag. Furthermore, my manual transmission shifts very nicely thank you very much.

That particular Getrag box is not as strong as that particular ZF box (hence the model numbers). Meanwhile, E46 M3s got Getrag boxes and those shift just fine.

Lighten up man, the shitty part was just a joke. Like people are saying, the getrags work great for N/A cars, but in the F/I world they dont do as well. Superchargers wear them out quicker and higher HP turbo setups can destroy them. Ask hobbit382, hes destroyed 3 of the getrag 5 speeds.

Its honestly no ones fault, as the gearboxes were never intended or designed to handle the extra power. Im not sure if its a question of being weak or inferior, but maybe just that the ZF is designed differently and handles power better.

My getrags shifts fine too, just upgrading to the zf before my turbo eats it

I can attest just how indestructible the ZF can be. Heard a story from someone who's ZF leaked so bad, that he filled the trans fluid only when so much was lost he couldn't get it into gear. My car had the original ZF "Unlimited Life" oil at 200k miles, only 1/2qt of sludge. Maybe someone can enlighten more info on this massive sticker on the trans, haha. Oh well, still works! They are also inexpensive.

I think hitbyastick, was, well... Were you hit by a stick? I would be upset too....

Mrbobmicjoe - I'm wondering if you had success with swapping the Getrag output flange to the ZF transmission? What driveshaft did you use? Isn't the Getrag transmission shorter than the ZF? I have a ZF transmission and a Getrag driveshaft and see that the driveshaft is too small in diameter to mate to the ZF guibo...

I kept my 325 differential, so in order to make that work with the ZF, i had to purchase a driveshaft from a manual 328. This driveshaft has the bigger flange for the ZF transmission, but will still mate up to your 325 differential.

If you really want to put in work, you can swap a 330 differential and then use a 330 driveshaft. Two options, up to you

You mean in order to make the zf 5 speed work with your 325 diff you used a manual driveshaft from a 328?
