Got my car back from the dealer, my s52 swap is MESSED up

[bmw332i]

Wow. s52 slave is part number 21-52-1-158-903 as per my s52 swap. I'd then have them take a look at your shift linkage, and see if everything was installed right. It sounds sort of like a case of, "this swap is such a PITA, maybe if I cut corners here and there, it'll be done easier and quicker" to me. Get that coding plug in, fix those diff wires, have that shift linkage looked at, and get some 93 in there, stat! Then see what happens to the car. Chances are that things will get better.

So use a s52 slave? God this is like the 9th time eveyone on this board says to do it one way, I do it that way, dosnt work, then I have to do it another way... Wont the e36 slave require a new master though? I thought it couldnt push enough fluid.

That's exactly why our 40+ page X50 thread scares me.

Yes, emphatically YES!!!! Use the e36 s52 slave. The part number I gave you is a good part number. My conversion was done by Schneller, and they gave me a parts list of all the exact parts you need for the swap. As far as a master is concerned, they used an e36/7 MCoupe MC for my swap. BMW part number for the MCoupe MC is: 34-31-1-162-915 . This part is also the same part number for the m50 e34 525i, and any 3.2l e36 M3, or any e36/7 MZ3 Coupe/Roadster. It's about $140 new. Of course, if you could find a used one from a parts car from any of the afore-mentioned cars, you'd be set.

I personally think the m5X or s5X swap thread needs to be culled of all the eronious bullshit. All the posts like, "good job", or "hey, how'd that thing go?", or "let me know about ______" should be removed.

[equate975]

Ok, so that was part of my question. I need a new MC to drive the e36 slave. Which I guess is ok, because my MC just blew... I will just run an e36 setup then. The reason I keep asking is because this happens to me ALL THE TIME like you said about that 40+ page thread is crappy, everyone is saying something different.

Ok so final verdict..

MCoupe Clutch Master Cylinder
e36 s52 Slave

Any objections? And the MCoupe master will fit into an e30 right? I dont want any more surprises.


As far as shifting goes, the rubber thing that holds the back of the shift linkage to the car broke apart.

[bmw332i]

Well, since my car is a 1989 e30 325i sedan, and I'm running both those things, yeah, it'll fit. I also use a 2002 brake fluid reservoir. BMW part #: 34-32-1-112-399. Then you need a couple (2) of master cylinder adapters, BMW part#: 32-31-1-121-911. You will also need some angular fittings (2), BMW part #: 34-32-1-102-282. And other than that, you should be golden. I'm sure you'll have figured out how to mount the fluid reservoir by this time. You're running a 325iX brake booster too, right? Even before my Brembo 330mm GT Big Brake kit conversion, this thing would out-brake near any modern BMW. Great pedal feel too.

dude
you dont need a new clutch master cylinder to run the m3 slave cylinder.

replace your master cylinder with the e30 part- it will be just fine, and replace your slave with the e36m3 part number that bmw332i gave you.

the master cylinder part number that he gave you, ignore completely- that is for an m coupe BRAKE master cylinder, not the CLUTCH cylinder.




if your clutch master cylinder has gone out- fix it with the e30 part. YOU NEED TO REPLACE THE CLUTCH SLAVE CYLINDER WITH THE E36 M3 PART REGARDLESS.

Good luck.

Fuck, you're right Addis. I didn't even see that he said "CLUTCH SLAVE" cylinder. If that's the case, then the slave that was used on my car is BMW part #: 21-52-1-158-903. It's also found in the e34 m50 525i, the e34 m50 530i, most e39 5 series, as well as the 3.2l e36 M3, the 3.0l X5, 3.0l Z3 coupes and a myriad of other BMW's. Sorry for not reading and understanding completely. I thought it was for your brake master.

you should have checked with schneller or the hot wings place before hitting enter
equate fix that little rubber thing holding the shifter carrier. how do you expect it to shift properly if thats fucked up?

[mspiegle]

My friend has a '99 M3 and just put in the UUC M5-clutch/flywheel kit. He was told by numerous people (including vendors) that he could use an e36 325 slave cylinder to make the clutch pedal a little stiffer (the clutch pedal is as easy to push as the gas pedal with the M5 clutch in there... so its a little wierd).

So yes, the e36 325 slave will work, but it will give a different feel.

wtf man, you have more problems with shifting than anyone i know... which made me think of this

eggbaker your scaring me.... theres lots of people on this board with lots of knowledge...but it gets kinda screwy with "opinions" flying around everywhere. i wanna start gathering parts... i wonder if that schneller place (or person?) would be keen on giving me a parts list...

Don't you have some work to do on any one of your rust-buckets? From what I hear, you're just like me now, a check cutter.

HEY... if equate can do a s52 swap on his own with little planning, anyone could ;)

[equate975]

Damn, this gets so confusing so quick haha. Ok, so e30 CLUTCH master, with e36m3 CLUTCH slave. The only thing that worries me about that is how it will engauge and disengauge, I dont want it doing that 1/4 on an inch off the floor with a huge amount of pedal travel.

And where the hell did everyone get off saying NOT to use the e36 slave? Thats what I have been reading since day one.
