found contradicting info, anyone clear up a G240 question?

[2.5-12]

I am doing my second M50 swap to my 1984 325e in a month or so here and I have most of this sorted from my old M50NV swap, but I want to run a Getrag 240 this time and need to know what fw/clutch and Pilot bearing to run versus the G260 swap I did in my last 24V car.

I have heard that I can use the M50 dual mass in the G240 and I have heard i must use M42 or M20 single mass in it. which is true?

with the M50TU, and getrag 240:

can I run the M50 TU flywheel, clutch, pressure plate and TOB?
can I run the G250 pilot bearing?
I use E36 325i 5 speed DS with backward E30 carrier bearing or do I use a stock E30 5 speed G260 drive shaft?

the shift carrier I have heard use G240 hardware or use G260 hardware, which is true?

does the G240 use the same pilot as the G250 or the G260?

[nokincy]

I'm somewhat in the same boat. I believe you can use any flywheel that will work with an M5x, but you must use the corresponding clutch and starter.

If you use an m20 single mass you must use the 323i euro throwout bearing.

The pilot bearing must match your transmission input shaft so either use the m42/g240 one or use a m20/g260 (I think they are the same)

Use the e36 325i or 323i driveshaft with e30 CSB for best fitment.

As for the carrier that is the part I'm most confused about. You can use the stock carrier and linkage, but they must be shortened by I've read 2 inches (can anyone clarify?) If you used the g260 carrier and linkage I would assume they would still have to be modified to attain the 10 degree angle.

Same boat and after reading and re reading I am opting to go with the m20 setup as to have better torque. For shift linkage I wanted to keep it not bastardized so I am going with the plug and play e30 320i linkage

I mated a 240 with m42 flywheel, clutch, pressure plate, pilot bearing, and starter to an s52. Driveshaft was two inches too long, so got a e36 325i manual to fit perfectly. The shifter arm and rod need to be shortened by 2 inches and ill be golden, i noticed the shifter arm from an early e36 325i manual was only a half inch off from where i wanted the shifter to be, but i would rather get it welded to exact fitment.

I did getrag 240 with single mass m20b25 flywheel, clutch, pressure plate with 323i TOB and m50/42 pilot bearing and e36 325i/s driveshaft.

I used the m20b25 (260) shift linkage and UUC SSK with the DSSR and it sits an inch forward but doesn't affect getting into gears.

I swapped the engine in my 97 Z3 1.9l for an M52B28.

Had a DM fly already just used the starter and clutch for the motor and all bolted up no issues.

[Roysneon]

How are you bolting the e36 driveshaft to the 240? Doesn't the 240 use m10 guibo bolts while the e36 driveshaft use m12?

[2.5-12]

alright guys, I know how the m20 flywheel starter work. I did that in my last swap but I didn't like it

from what's been said the m42 fw/clutch/pp/tob work (m50 stater same as m42?)
but can the m50 dual mass be used in the 240s bell housing?

and if so, can the 240 use the m50tu pilot bearing or is it the larger spline like the 260? this last part was answered I see. G240 and G250 have same Pilot.

Good point, im planning to use sleeves(like someone else has done) or just enlarge the holes on the 240 and use all larger bolts

Well the Z3 I swapped is essentially a 318ti so the DS and rear drive are the smaller versions like the M42 E30's. So there was no funny biz.

I used the DM fly on the M52 and it worked no problems at all, not a damn one.

Very ganksta



I will say that I never had an issue in the 6 months I had the car before I traded it in but I always had a pit in my stomach on a hard launch.

I am not entirely certain, but didn't the Z3 have a Getrag 250 not the 240. I would love for the 240 to be able to work with a stock DM flywheel and e36 so I can get rid of my lightened M20 fly. Real OEM is not showing the Z3 for some reason but they show the Getrag 250 in the e36 318ti.

[2.5-12]

alright, so it sounds like if I do this:

M50TU starter
Getrag 240 (From M42 E30)
M50TU flywheel/clutch.pp
G250 pilot bearing
stock E30 G260 slave cylinder
G260 selector rod and carrier
E36 325i drive shaft (manual) w/reversed E30 CSB


do I use G250 or G240 throwout bearing? G250 I'm guessing

Whats with the G260 sel rod?

[Slovik]

Don' reinvent the wheel, BMW already makes the shift linkage parts for a 240 moved back a bit for the 6 cylinder part #s 25111220759 & 25111220835 just don't jump the gun because and who really knows if the flywheel and pressure will actually fit the 240 bellhousing, if they did a lot of people would be using them. I heard one guy clearanced his 240 to work but I don't know how much work was involved. A used zf is only a few hundred dollars and we know that will work.

Order went out last week for above shift linkage from pelican. Backorder for 3 weeks.
