Flywheel DIY? - BMW Forum

WALSRU · 09-10-2006, 07:41 AM

Has anyone here replaced their own flywheel? I'm looking into getting a 10 pound by the end of the month and I think with a weekend in the garage I can probably tackle it myself. Any links, tips, hints, pics, etc.?

MCS - Modification Tutorials: UUC 8.5 lb Flywheel with e34 M5 Clutch

here walsru, see if this helps. it's the only one i could find right now. just ignore the M5 clutch part.

Thanks, I'll definitely use that.

Went to pick up a part for a different car yesterday and talked to my mechanic about it. The flywheel I can do, I'm a little more confident than I was. Of course, something else came up. He can loan me a stock cam so that my car isn't out of commision while they're being reground. That was the only reason I was going to do the flywheel first.

256 cam kit or 10lb aluminum flywheel. That's the question.

Hey walsru- if i were you i would do the flywheel first. why?
first off, it's a good deal cheaper and not as labor intensive. plus with all of that rotational mass gone, your car will pull alot harder. my cousin's e30 has just a chip and lightened flywheel and he pulls way harder than me.
Also if you do the cam kit yourself, you might need a special tool for taking the vanos off. just my two cents.

His car doesn't have Vanos.

Wurd

Plus, since no one offers the 256 cam anymore I'm getting a regrind. And it's only needed on one cam (swap intake to exhaust side)! So for around $400 either way the price is really close.

I'd go with the lgihtened flywheel for your car. Those faster revs will defntely help you out. Put in shorter ratio differential and you could defintely have a pretty decently accelerating vehicle. From there save up for a supercharger and you'll be set to spank most of the cars on the road.

+1 i read somewhere that ever like 6 lbs off rotating is equal to like 150 lbs of regular weight... not sure how accurate it is... but i know from personal experiences.. its a nice mod to look into...

The cam is supposed to put me at about 200whp tho . . .
