My engine's in, with the M20 clutch kit. E36 M42 converted to E30.

My dualmass flywheel didn't have any spacers.
I first bought a singlemass flywheel for which i would have needed a spacer between the flywheel and the engine which was a no go. So i found another flywheel which is about 2kg lighter and fits perfectly.

The first pic is of the right flywheel.
Second is of the flywheel which hit the oilpan.
Third is my dualmass M42 flywheel.
Forth is my M40 flywheel.

Note: the right flywheel came off a 2.0 M20.
Now the rest of the pics. Tomorrow i'll do the electrics ad i'll have to see what i'm gonna do with the exhaust, because now none of either my E30 exhaus nor my E36 one fit.

i know it's an old thread but i have to ask. The Changing of the Flywheels from M20 and M42. i have an E36 M42. I see all this talk of spacers and clutches and such, all i know is my FW weighs an ass load and i know with a lighter one my accelaration would drastically increase. I was looking at buying a light weight one online, but if i can get a less expensive one i'de be interested. Now, when there's all this talk of the clutch change over, whats invloved in all that?

Does the tranny I plan to use make a difference with the TOB when I do a M20 flywheel conversion? I'm putting a M42 into an E30 325i with the 265 tranny. I'll be using a M20 starter and flywheel. Do I need the 323 TOB?

Thanks!

I used the 240 tranny and the 316i TOB and it works fine so you shouldn't have to change it.

I'm going to ask the obvious question which nobody has yet asked .

Can the M20i starter be bolted to the M42 ?

Seems that would cut out the hassle of switching thew gears and potentially run in to other problems .

I'm new to the 4cyl's but looking at pics on WoldPac it seems like they are laid out the same and that they could be interchanged .

If nobody has an answer then I will compare the two soon when I drop my trans .

you bring up a good question there...i have an M20 starter and a 240 tranny laying in my garage.

i dont know why i didn't think of this earlier! i'll try it out tomorrow.

that would be really nice if that worked...

Yeah that would eliminate one potentially troublesome step and make this more of a "bolt-on" swap if the M20 starter is found to work as a whole .

I figured that in the write-up that was linked theguy was a 318 guy and maybe did not have access to a spare M20 starter , especially since he bought the gear new .

I on the other hand I have plenty of M20 starters around and would be taking the gear directly froma used spare starter if need be .

Although the one guy seemed to have a used M20 starter to do the gear swap .
But I'm guessing he never thought to try the starter as a whole , I'm basing this on the fact the he was not mechanically inclined enough to even get the gear swap to work .

In any event we shall see .

does anyone have a picture of their starter with the m20 gear? im wondering if i put mine on right

Teaguer · « **Reply #42 on:** January 16, 2007, 08:41:06 PM »

There a pic in post# 16 .

Not a direct pic of the gear but that does not matter as it should look the same except the fact that the gear theeth are closer together on the M20's .

nickmpower · « **Reply #43 on:** January 16, 2007, 09:47:35 PM »

yeah, from a car that wont start

nickmpower · « **Reply #44 on:** January 21, 2007, 03:27:24 PM »
