An s52 clutch will not bolt up to your M52 flywheel if thats what your asking. They are both the same pieces from bmw (240mm of clamping force) except they moved the dowel pins around to prevent swapping. It's sort of like your waterpump on the S54 and a CSL M3. Same pieces, besdes the dowel pin placement. I think its there excuse to jack up the price/add hidden taxes to the M cars.

Perfect. I may have to go with the m52 setup due to this gem that passed over my radar this weekend:
http://forums.bimmerforums.com/forum...ght=csl+airbox
PM'd the gentleman about what I could offer for the setup, but my offer will still completely derail this thread as a "Budget Build" haha.
Since the m52 clutch/fly will work, couldn't I just bolt up my 5speed to the current s54 clutch on the motor? It has 62k on the clock and seems to be in decent shape.. I wonder if the m52 setup will work better with +/- 8k on the clutch opposed to the m3 setup with 60+.
Something to ponder.
Emailed VAC on which bearings/ rod bolts I need since there are different sizes.
we measured out the Bearing ID to 48.75mm/1.919 and the crank OD to 48.71/1.918
here's the VIN if you guys have any ideas. I believe the motor is a 2002 production unit.

here's the printout BMW Canada sent me as well on the bearing info

Unless they changed rods during recall (unlikely), you need 11mm "early" bolts with Jan '02 production. Change-over to redesigned rods/bolts came in early '03

Thta's what I thought, but I wanted to double check. Any idea on the bearing size?
Assuming the crankshaft is OE and never turned due to damage, then standard size...of course, confirm with VAC when ordering as they are not returnable as I recall when I ordered mine

They emailed me and confirmed 11mm and standard sizing. ordering both those pieces, ebay headers, bimmerworld install header kit, s54 fuel pump stuff, gaskets, akg mounts, vanos replacement bolts, diff support and a new oil pump nut.
It's all starting to come together.
I bought 2006 engine for 5K, so I don't have to do anything to it, just install and enjoy. IF you have to dig into engine to change the bearings and water pump then it will cost to get it in good condition same as if you bought newer engine for more money.seller understanding my budget and becoming excited with my project, he gave me the entire pullout for under 2900 bucks. I am so thankful!
The motor has 62k on the clock and was a complete pullout with absolutely nothing wrong with it. I pulled the bearings out yesterday and look fantastic. I'm changing out bearings and rod bolts for race application pieces that will give me peace of mind on the track. The water pump works perfectly. I have access to a machine shop and doing the work with 0 labor cost.
The race bearings and connectors were 564.90 shipped... add that to the cost of the motor and I'm at 3364.90.. well under your 5k and mine will be prepped for track use.
I would advise you to do the same thing if you plan to use your s54 for track purposes to keep your mind clear of worries when you're pressing 7800 rpms on a racetrack for 15-30 minutes at a time at 5 runs a day
Cheers!
Maybe...rod bearings and vanos bolts are potential weak points on ALL S54s. Lower mileage helps reduce risk but not a guarantee. I've seen heavy wear on low mileage bearings and little wear on some with much higher mileage. Checking/replacing is just an insurance policy that's a lot easier to do when motor is on a stand than in the car.

OP, while motor is out, you should replace CPV o-ring (no need to replace entire CPV). If it's not leaking now, it will and it's a BIG pain to fix with motor/headers in car. New o-ring available here

S54 clutch will not work with a ZF 5 speed. The tranny input shaft is different sized between the ZF and the E46 M3 6 speed Getrag.
It's not speed that kills, it's the speed difference that does. Obviously you aren't going fast enough.

I read a list of the 100 things you MUST do before you die. Funny, "Yelling 'HELP'" didn't make the list!
E46 M3 flywheel and E46 M3 pressure plate can be kept and friction part number 21212226958 substituted for E46 M3 large spline friction disc.
To adapt a S54 engine with ZF 5 speed the BMW factory utilized OEM part number: 21212226958
This part is used for e36M with s52 engine and for z3M; the USA only s52 pressure plate/clutch kit is shared with the E36 Euro S50b32 (cooper should know this one.) the E46 M3 6 speed manual has the Big imput shaft and uses a 240mm twin mass set with big splines.
Late model Z3 M roadster and coupe had a Zf 5 speed and a S54 engine;
for OEM BMW adaptation
One can just order this friction disc.
A new M52 clutch should hold the S54 power, the rpm's may kill it quickly though. M52 original clutch set has been proven with ESS
supercharged 3000cc power in many chassis (e34/e36/e46/e39)
M52/S52 240mm dual mass flywheels have identical dowel rods and bolt patterns; I have verified this many times myself.

You need that part number in order to run a clutch that is specific to mating an s54 with a zf-speed. Stick with the dual mass flywheel. It is not worth the headache with trying to adapt ebay parts for the minimal gains from a light weight flywheel.
All of this is great news! Wagan helped me out with a few emails and informed me that I should stick with my m52 clutch and flywheel.
Clutch info, check.
I can also reuse my m52 header hardware+new oem gaskets.. check
What I just put in the mail as of 10 minutes ago:
Fuel pump, housing, regulator and MAF+ airbox top to modify the cylinder holding the MAF: 300 used from Steve on the forum
CPV O-Ring (2): 9.00 from m3forum member
VAC Race Bearings and Rod Connector bolts (standard bearing sizing and 11mm bolts) 584.90
Ebay Headers: 160.00
AKG Motor/Tranmission mounts: 194.00
Skipping the new ebay clutch and going with my almost brand new m52 clutch with stock dual mass flywheel.
PROGRESS!
Or a S52b32 clutch if the M52 clutch wont hold the S54 rpm's - it will bolt up with original dual mass M52 flywheel (30lbs) if desired or s52 dual mass (22lbs)
S52b32 clutch is OEM s50b32 (euro 321hp) and has been proven DD/wangan friendly with my own S54b32+8400rpm's
