[s-cars] How low can I go? (numeric gear ratio)

[Michael Bess]

I recently installed an EDU 6-speed (.68 6th gear).  RPM/Speed data in 6th
is:
2400rpm  60 mph
3000rpm  75 mph

Not as low as you are hoping for, but I have seen a slight improvement in my
gas mileage if I go easy on the go-fast pedal

This might be much easier than you think.  I believe some of the euro 
diesel transmissions like the DPJ might fit the bill. SJM lists it's 
ratios as (3.5, 1.89, 1.32, 1.03, 0.67, 0.56) (1st-4th matching the 
rs2).  The DPJ also has the wide/flexible first and 4.11 to 1 FD, of course.
