Javad,

It is not necessarily for the clamping force or beefiness I am looking for, 
although that wouldn't be a bad thing.  It is about  lowering flywheel 
mass.

I have a 90Q flywheel that weighs about half of a stock flywheel - I plan 
to provide more details on this later.

What I need is a pressure plate that will work with it, and a disk that 
will fit between with the correct splined hole to fit the 4000 
transmission.

I have deduced that a 90Q pressure plate will work - duh.  Either a 200Q or 
5000 disk should work with this combination.

Now, my problem is that I pay more to mix and match disk and pressure plate 
rather than buying a kit.  I have seen many used pressure plates that are 
in good shape, so if I can find a used one, then all I need to buy new is 
the correct clutch disk.

I located a relatively new 90q pressure plate, but it is sold, but he has a 
20 Valve turbo flywheel, so if I can use that, the price is right.  I think 
it isn't correct though, and is probably more like the 200 flywheel.
