The semi-Comprehensive M60b40 into E30 swap Q&A

[JGood]

Came across this BMW document, thought some of you might find it useful. It's just a brief 15-page overview of the m60 engine.

according to metric mechanic, the e34 535, e36m and 328 all share the same lightweight flywheel option. UUC lists their 6-puck compatible with m3/328...

Well, that's good info. If there is crossover compatibility, as you said, it really opens up the HP clutch options and makes the 5 speed a pretty damn good choice for this swap... Now we just need it verified...

i'm pretty sure that a few e36 m52 guys run e36m clutch setups on their cars, which are also 240mm and share the same trans.

any input as to whether we can expand the 5spd-240mm flywheel combo to include e36m clutch kits?

it would open up the availability of aftermarket clutches pretty nicely.

I believe and correct me if I'm wrong here Bruce, that the issues are the stack height of the components and the mounting locations of the PP, not the diameter of the friction disc. I'm not sure how many different clutch kits Bruce actually purchased and tried in his R&D. If an E36, 328i owner is swapping into an M3 clutch setup with no mods and no ill effects, I would assume that the same would hold true for us 5 speed/V8 guys...

So on the 5-speed, from another thread on the subject, here is what we came up with, and it *works*:

"Basically, there are three models of BMW that used this clutch kit - e36 328i (all body styles), E39 528i Sedan, and Z3 2.8 Roadster. The OEM clutch kit is part #21211223602, but again, we used the Clutchmasters upgrade for the application. Given the torque differences between the 2.8L six, and 4.0L V8, I would be very hesitant to use a stock clutch kit. We chose a lightweight flywheel, but it is dimensionally identical to a stock flywheel, so the stocker should work (just don't drop it on your foot)."

Flywheel is e39 540i. We used a JB Racing unit.

So now, when you do a search on "5-speed clutch", there will be yet another hit :-)

Here are 3 pics... the most important part is the thin neck after the hex shape, which allows it to go into the flywheel opening and then offset slightly to reach the head of the bolt...







It is a T60 and this one is made by Stahlwille

Yep.

I'll take a couple of pictures of it when I get to the shop this morning...

i saw that autozone has long torx socket sets that have worked?

[Jean]

It has to be a LONG THIN socket to clear the flywheel...that design just sucks.

[mkcman17]

is it a t50 or t60 bit?

[bmwmech1]

where can i get the bit to remove an m60 flywheel? found one at the yard and had a mental implosion when i saw the torx was actually a 5 point.

ebay or UUC... they're not cheap ~$50-60

The V8 stuff is not that common here in Iceland and with our currency exchange rate with € or $ is not good :( But I was wondering why no one uses the oem booster+mc since its a good combo for my brake setup.

The problem is that the diameter on the original booster is not very good from V-engine point of view :)
