[urq] gearbox

[Steve Eiche]

Pat,
There is no six speed gearbox that will fit your ur q without modifications.  The shift mechanism, mounts and driveshaft must be changed.  You may also have interference with the chassis that will need to be dealt with.  If you are going to go to a six speed, get one from an S2.  The S2 gearbox has a different tailhousing than the S4 box, as was as the shift plate and mounts that you would need.  You will also need the S2 driveshaft.  As for the rear diff, you will want one from an '84-'85 80/90q.  That will have 4:11 final drive as well the proper case to fit the ur q subframe and axles.

Any way you look at it, it will not be inexpensive to put a six speed transmission in an ur q, even if the gearbox itself is only 350 Euro.

I've got an 1981 ur-q under restauration . 
I've bought the car without engine and gearbox . 
Stock gearbox was an UG 5 speed gearbox with 
35/9 FDR  . 

The local wrecker has a six speed  gearbox from an S4 
and wants 350$ for it . Now this is a gearbox 
with 37/9 FDR . 

I think I can put  this six speed in the car , on condition that I change the rear diff to 37/9 .
 
The only problem is that I don't have the stock gearbox , so I can't compare 
it's dimensions to the six speed . And I don't want to end up with a six speed 
that doesn't match the driveshafts and or shifting mechanism . 

If somebody has ever done this swap , any comment appreciated . 
Or  if someone has a stock box lying around , and could take 
some measurements  that would help to .
