How-To's / DIY M20 flywheel conversion

« on: August 07, 2010, 10:39:26 PM »

I think alot of people are getting confused about the references to 323's which is E21 not E30 version which as far as i know is a detuned 325i (still 2.5L) and should still have the same part numbers for flywheel parts and starter. E30 325i flywheel weighs about 19lb's and a E21 323i is 13lb's. changing the pinion is a pig and would not advise anyone to do it because of the amout of problems some people have had with it so on the setup im fitting in the next week im using a later 323i which many say is will be a direct fit, should make things a little more fun and i must point out that even with the 19lb 325i unit used in my last conversion it was well worth it and have no idea why BMW didn't make it this way in the first place.

Engine + Driveline / M42 single mass VS M20 single mass conversion

I tried to figure this one out just by looking at part numbers and found it confusing.  Pelican Parts (whose website makes browsing quite easy) shows  3 different clutch disk part numbers depending on production dates, with changes occurring on Aug/Sept 85 and April/May 86.  BMWfans shows 4 disk part numbers, with changes on Sept '85 and May '86 which agrees with Pelican.  But they also show an additional part number with the designation For Vehicles with: 325 (V002A) = Yes.  I don't understand this note at all.

It is this last part number that matches what Pelican is actually offering for the 325i, which implies that later 325e with SM flywheel could indeed use the 325i disk.  

Now, looking at the pressure plate part numbers on BMWfans, there is a change at May 1986, with different pns before and after.  Pelican shows the same pressure plate for 325e up to April '86 as is used in the 325i.  I get the impression that this date, April '86/May '86 is when the 325e changed from single mass to dual mass flywheel.

Not sure if any of this helps, but bottom line is to find someone who has hands-on experience with your year of car for the final word.

Yeh too confusing but cheers anyway

Does anyone know the difference between the 325 clutch and the 320/323 part as i've found this but unsure if there is a difference in fitment or would I be correct in assuming the pressure plate is weaker/softer??
its listed as:
FITS BMW E30 320i 323i 1983 TO 1991
228mm DIA PLATE
Any help would be appreciated and my apologies for keep asking random questions about the clutch but the cheepest i can find a 325 cluch near me is nearly £200!!!! as i already have a barely worn in stage 1 cluch i dont want to throw nearly £600 down the drain for a mod that I've done before and have had good results but not worth that sort of cash and also cant afford trial and error approach.

Cheers thats soundsabout right for BMW but ive googled it all day and still not fand any relivent info and a search of the forums just ends up with every thread with the words cat or plug in them but have trallled though and still cant find anything. Can anyone tell me where this plug is situated on the car or any links with relivent info on this plug??? like I said previously I've found the sensor connector under the battery tray (C140) but this never had any blanking cap/plug and was open to the eliments so I'm guessing there this plug must be elsewhere.

Another cheap ebay item but I'm very supprised by it as I would not buy cheep knock offs but it was a present from my bro so decided to give it a go because my bushing were soggy. Had no fitment problems, its secure with no rattles, quility is great, looks good works a treat and i really am well impressed! Big thumbs up.  BTW this isnt my first short shifter so i have the experience to say i would'nt buy another rip-off priced unit again and would like to hear some more feedback from anyone else that has used this shifter.

Engine management / Adding o2 sensor on m42

Just found that the connector (C140) and that its located on the bulkhead under the battery tray. Will have to wait to get to a scrap yard to get the cable from C140 to the o2 sensor but couls till do with someone to confirm if the ecu will just recognise and adapt to use the sensor appropriately or if theres more involved with this??
It would be greatly appreciated if anyone could help me with this.

Could a 325e clutch and pressure plate work or does it have to be a 325i??

Kl its nice to know im not on my own with this I've PM'd "dude8383" to see if he can shed some light. Even 13.4lbs is still alot lighter than the m20 unit and should make for a good revvy base in an e30 as I done the M20 conversion to an E36 about a year ago and even on the much larger car it was very noticeable.
Also some people have been saying that the later 325i starter will fit without modification which i did not find to work last time, I think it was from a 1990/91 so does anyone have any more info on this or part numbers??

Is this in reference to a E30 323i or E21 & I'm guessing either way its still the same 323i TOB? As for the clutch does it have to be for a 323 or could a 325 clutch be used as im guessing the 323i has single mass where as the 325 has dual so clutchs would not be interchangeable?

I have a ltw 323i flywheel that weighs roughly 11lbs.

I paid less for the whole deal that the M20 clutch kit.

This by far is the best option because the flywheel is lighter than ALL three you've mentioned. Not sure about cost or availability but I got lucky with my purchase.

323i Flywheel : $75
323i TOB: $63
M20 Clutch: $100


ZERO chatter with this setup.
