clutch and flywheel
 

hi my little E36 316i compact m443 1.9L, is time to change clutch(maybe flywheel)

does any one know 6 cyc clutch and flywheel can fit 4 cyc car?

is it direct fit?

yes and no.

a M20's flywheel and clutch will bolt in, but you will also have to change the drive gear in the starter to match the new flywheel.

you can also get a european single mass M42 flywheel/clutch and keep the original starter.

i have a single mass E30M3 flywheel/clutch and have been wanting to see if i can get it to work. i know that the crank bolts and spacing are the same, as well as the splines of the trans input shaft and the starter ring gear. i just have to work out the correct stack height.

Do you have A/C?

I'm fairly certain that an M50, M52, S50 or S52 clutch/flywheel combo will bolt right up to your motor just fine. I know they'll bolt up to the M42 and M44 engines, and you won't have to deal with the starter bullsh!t that Tom D is talking about.

Why do you want to install a 6cyl clutch/flywheel? Reason I'm asking is because unless you're making 6cyl power, it's hardly an upgrade. The larger clutch will weigh more, thus require more power to spin. Keep in mind, whatever clutch setup you go with, you'll need to use a matching flywheel so that the clutch disc makes the appropriate amount of contact.

As a performance upgrade, you can try to rig up some sort of single mass setup like Tom D mentioned, or you could save a headache and probably some money by purchasing an aftermarket lightweight flywheel and corresponding clutch. OEM flywheels are expensive and heavy.

I'm running a UUC stage2 flywheel(8.5lbs) vs. the stock 40+lb dual mass FW with an e34 M5 clutch, e36 M3 slave cylinder, 318/325 clutch master cylinder(not to be confused with the brake master cylinder which in my case is an e36 M3) and a steel braided clutch line. It should be noted that the e34 M5 clutch is much heavier than the 318ti and M3 clutch, however the gripping force is almost double at about half the weight of a stock setup.

My setup cost about a thousand US dollars, there's cheaper brands out there. Fidanza makes nice lightweight flywheels that are significantly less expensive. Heck, an OEM dual mass flywheel costs about a thousand bucks.

here's another option.

^^^Good stuff. Those look really nice and well engineered. FWIW, companies like JBracing, Fidanza and UUC stand behind their products. They offer exceptional warranties, customer support and replacement parts. Not to mention their products are designed and tested in labs and proven in the racing environment. You won't get that from manufacture's that sell their products exclusively on ebay. Quality and support comes with a price, but it's money well spent. Especially when you're talking about a part that spins at 7500 rpm and can rip your leg(s) off if it fails:eek:

I just bought a JBRacing LTW Flywheel for an M52 i'm swapping into my Ti. The flywheel is for a M52 not a M3. I'm assuming I just use a clutch with the same diameter correct? And also do I have to change my slave cylinder?

Jess, have you searched on bf.c about the UUC Stg 2 flywheel problems? I've seen a few threads where the people warning other have to refer to it as the "blue flywheel" so that UUC doesn't have the thread locked. There's enough conflict about it that I would probably never run one. That's also my opinion for most UUC parts though.

Yeah I've seen those threads before, after I purchased mine of course. But I've known several people who have run the same setup with no problems. We'll just see how it goes.
