transmission of choice?

[cormier]

g240s came in e30 318i
g250s came in e36 325i
g260s came in e30 325i

zf320s came in e36 m3/328i

iirc the e34 m50 had g250s as well

any insight into the g250? ive heard its weak -- I got one right now came with my s52 engine should i scrap it for a 260 for the swap?
also anyone know if it has the same bellhousing/m3 clutch issue as the 260s or can it be used without modification?

I have never seen any supporting facts about the getrag 250 being weak. I got one with a package deal so that's what I plan on running....

i'm a bmw master tech. I have been workin on these cars for over 5 years now. What i have personally seen is 2 getrag 250's go bad and 1 zf but have not seen any 260's go bad. One 250 lost first gear and the other lost 2nd and the zf had something get loose in the trans and wedge itself against a gear and break a hole about the size of a half dollar piece in the case but still worked i hope this helps someone. Its rare i get to post here i have read thousands of pages here glad i get to contribute for once.

Hey guys I have a question here. I am doing the m50 swap into my e30.
M50, Getrag 260, m20 flywheel, m20 performance clutch.

We put the flywheel on last night with the shim on the outside of course, bolted it on and now the crank won't spin because it's hitting the rear cover.

Am I possibly missing a crucial element in this?

Thanks guys

The oil pan needs to be clearanced to not hit the flywheel. Very easy to do with a decent grinder. I did this same thing on my first M50 swap 5 years ago and thought the motor was seized up!

[WADE30]

The oil pan AND the rear cover? Because the rear cover is of course flush with the oil pan. You mean grind it down in that area where the pan and the rear cover indent outward toward where the flywheel would be?

Thanks man, I appreciate it! Would you might happen to have a link to show this procedure?

So you are using R3V as a reference in your work? If so, gotta love that!

Join in the discussions more, man...we need professional opinions all the time!

I don't get to post much because there are others that know alot and are on more frequently then i am. So they get to answer things

before i get a chance. I wouldn't call this reference for work i don't get to work on e30's much here in NC in jersey when i was a bmw

dealer tech there i did. But still it was only timing belts, valve adjustments, clutchs etc. nothing exciting. I will put my in when i

can.

just the oil pan. you should be able to tell where the flywheel is hitting if you've got it bolted up... thats what needs to be modified

You saved my life! Thanks man, I just grinded it down and now there's a couple mm of clearance between the pan and the flywheel. Excellent!

awesome. no problem

This thread is amazing!
Now I have a M50B25 that I got a 260 for. The 10* offset doesn’t worry me as I’m in a well equipped shop. The problem is. I think I got a duel mass flywheel. Will that fit? I got a new clutch with a heavy duty pressure plate. Will I need a new flywheel? And I presume I use an old m20 starter with this right?

Ps. really sorry for the grammar issues. i was writing this in between classes and forgot to take the time to proof read.

[hoveringuy]

I think you'll be taken seriously if you take a minute to edit the spelling/grammar in your post 'cuz its reely hard to rreed and prolly gives head akes.

Starter and flywheel need to be the same.

Can the ZF's take e34 m5 clutches/flywheels? Thought i read that somewhere :)

[SamE30e]

G240 doesn't tilt the shifter. The M50 with the E36 arms sits the exact same as the M42 does.
