drive ratios for '90 80q
I recently bought a 5-speed '90 80q and I noticed the the gearing is
significantly different than on my old '82 5k. At 65mph the engine is turning
around 3k rpm (seems high to me). This means at *real* cruising speeds the
engine runs around 4k to 5k rpm...
I know these engines are "bullet-proof", but since I do a lot of
highway driving, I think I'd like greater fuel mileage and less engine stress
at the expense of performance. So here are my questions:
Is changing gear ratios advisible?
Is a car's gearing modified by changing the final drive ratio? Is
changing the final drive ratio a routine or complex task?
What is the drive ratio of a U.S. 80q? Is the European 80q different
(it must be!)? What is its final drive ratio?
