This is very good to know. My G260 has its 2nd and 3rd gear synchos burned and I'm sick of double clutching everywhere. Looking at either rebuilding it, or swapping something else in. Will be considering this.
Hi! I'm looking into swapping my m20 (520i, Europe, manual) e28 with a m54b30 and the same transmission you're using. I was wondering how it all mounted up (trans mount, bell housing, flywheel & clutch combo), do to happen to have this documented anywhere? Thanks in advance!
If u are using 6 speed you will need to build the mounts. I have my engine mounted a little further forward than the stock m20 was since the transmission would hit the tunnel. Stock clutch from whatever car the trans came from.
Thanks for the quick elaborate response! I see, did you have to make custom engine mounts to be able to move it further forward? I’m thinking about buying the ones from e28goodies, but won’t if they don’t fit with this trans. Were there no issues with regards to the clutch arm/fork/mechanism? Almost seems too good to be true to be bolt-on :).
@@apple95FTW yeah I built my own custom mounts. I chose to build my own because I needed to build the transmission mount anyways. I positioned the engine up enough for the oil pan to be level with the bottom of the subframe, and moved it back as much as I could without cutting the body. It is very tricky getting everything in position and keeping it in position as you mock up the mounts. If you can afford to try the engine mounts from e28 goodies I would just to give you something to go based off of. Who knows, the trans might fit as I’ve seen two different six speeds (one is a lot smaller). Also if you go with building your own keep in mind the driveshaft needs to point exactly to the center support bearing to prevent the driveshaft flex disk from failing prematurely
@@apple95FTW also, I couldn’t believe it would be simple plug and play for the clutch. I used e46 zhp flywheel conversion/ clutch kit. I even reused the stock e28 5 speed slave cylinder and have had no issues. Clutch completely disengages when pressed and feels OEM
@@Loudassbmw amazing job! And sounds quite doable. I think I'll order the mounts just for template purposes (or maybe even to be modified). Keeping everything in position will be a hassle. This is my first ever engine swap, and I'm trying to prepare everything as good as possible. The two trans sizes still share the same type nr? I've got my eyes on one from a 130i (e87), hopefully that's the right size. e46 ZPH stuff is hard to come by here, I do have a stock flywheel from a 330i e46, that might work. In any way, thanks for all the information so far! I'm planning on starting the project this spring, just finished all bodywork and suspension, should be a good base for the swap now. I've added you on instagram, will send you some pics/statusupdates/questions if you're interested.
@@Loudassbmw i’ve been having alot of slave issues with different setups i’ve ran in the past i heard e36 325i slave was the way to go but i’m just not sure

Thanks! have been looking all over internet if it fits in tunnel or it needs modification
Shoot me a dm on instagram @loudassbmw I can shoot over some more pics and info
Keep us updated

Will the 6 speed transmission and clutch kit you got from FCP euro work on a M30 motor?
I believe the m30 engines use a different bell housing pattern, since it’s the BIG 6
Yo where did you get that crossmember!!!
The transmission mount? I built it myself out of 3/16 thick steel. I still have it and not using it anymore since I swapped the engine to an m52
any picture of the mount you used with your m52 setup ?
Dm me on IG @loudassbmw
@@Loudassbmw okay bet i did
what slave did you use ?
I used the stock slave that came in my car with no issues. Typically you’d use the slave that came with that trans
@@Loudassbmw i’ve been having alot of slave issues with different setups i’ve ran in the past i heard e36 325i slave was the way to go but i’m just not sure
@@Loudassbmw oh shit dude i’ve seen you drifting at irwindale
@@Loudassbmw do you still have that tranny brace ?
