[urq] Hydraulic Pump attachment

Using the 83 UrQ hyd pump, what have others done for attachment/alignment to
the pulleys to the block on the 93 AAN motor?


There’s no way I’m getting the older hyd pump into the AAN bracket, might
work if I reworked the bracket to have a wider bracket hole spacing, and
machined out the hole on the face of the bracket. There doesn’t seem to be a
way to get the older brackets to attach to the newer block of the AAN,
without an intermediate bracket similar to what was used on the original
motor. Could use the newer hydraulic pump and bracket from the AAN, but I’d
wager the newer pump would most definitely blow out the seals on the older
style rack.


Has anyone done a switch to the 034 steering rack?


Short ratio steering rack that will fit any 4kq/80/90/Coupe, etc. Instead of
3.5 turns lock to lock stock, this rack has been modified to 2.5 turns. The
result is a rack and steering response that feel more like an EVO than an
Audi, with fast, precise response. A must for any sport related driving. An
OE ZF rack is rebuilt and modified to perform "like new" with the shorter
ratio response.
