Transmission mods?

[Michael Stricker <stricker@ll.mit.edu>]

I've stumbled across some information from some old audi shop manuals I 
have as they pertain to the quattro transmission.  Apparently there are a 
few different 5th gear gear sets.  One of them is a 27:37 gear set.  
Since I am still trying to determine the best/easiest/least costly method 
of reducing the engine speed in my 1990 Quattro coupe, I thought that by 
replacing the current gear set with this one, I'd achieve what I 
want...2640 RPM at 60 MPH.

Does anyone have any experience working on the quattro manual 
transmissions at this level?

Thanks in advance for your comments.
