Re: 4 KQ gearing

Harrison, I guess you do know. What an unfortunate way to
find out.  For what it is worth my car is the special build
with the q stitch upholstery and a Jan '87 build date
(plaque on inside of drivers door).  And yes, I'm positive
I have the 3.89 gears. Curious though my odometer and
speedometer were always off from the time I purchased the
car. Seems the Speedo gear in the transmission is better
suited for 205 60 15 rather than the 195 60 14 specified
for the car. That was a clue my drive train may have been
earmarked for an Urq since the transmission ratios are the
same as some of the later urq's.  Any one else able to
confirm their 4kq has these gears? in 4th (1.07) & 5th
(0.78) that would work out to about 18 and 22 mph per 1000
rpm  respectively in a 4Kq with the 3.89 finals.  I don't
believe the 5Kq series ever got this particular gear set.
