I've been looking around for a while now, trying to find a reasonably priced clutch which will handle over 400lbft of torque and still be easy to use on a day to day basis.

Was having a nosey around the realoem site and spotted that the E46 330Cd has a manual gearbox option.

Had a search on google and it appears that the clutch is good for at least 410lbft!

Question is, will if go on the gearbox splines of the getrag 260?

I guess whether bolts straight up to the M20 fly isn't so important as that could be re-drilled to suit.

What probably is important though is whether or not the E46 clutch would be just too big for the M20 fly.

Whadda people reckon?

Edit, think realoem's answered one question! The E46 clutch is 240mm in diameter whereas the E30 is only 228mm.

No, it wont go on your Getrag 260 splines, the latest clutches, september 2003 onwards changed to 22 toothed spline which is not found in the same diameter on any other mainstream vehicle.
Dont forget the clutch is also dual mass and weighs as much as a small engine on its own :)

Another E46 clutch does come in 228mm, 325i I think, but like I said they are all dual mass so have solid clutch plates which I doubt you would want coupled to an M20 fly for everyday use

Hi,

TurboBrown- we have recently used a E39 525 D Clutch for
a S54 Engine, whereby we wanted to loose the 'SAC' Mechanism.

Diesel Cover Plates handle much more 'Torque' and are a effective
way of uprating the holding/clamping force on a tuned petrol engine.

So in your Case, why not purchase the complete Disc/Coverplate
and then source a used disc with the correct spline/teeth and have
the disc re-lined. I expect you already have one.

Several firms do this for around 120-150, and you can have a mix
of Organic/ Kevlar or Organic / Cermetallic which will give
a little better grip when it warms up.

Organic Clutches start to slip at over 450 degree, where as
'Mixed' linings are good for around 600-700 degrees.

The benefit of having the 'spare' disc of the new clutch is so that the
company that reline it, can use it as a template for the correct thickness
of lining, and make sure the 're-lined' disc is balanced.

Not quite out of the box, but a lot cheaper than an uprated clutch/disc.

Regards,

The Gorilla.
