hi guys , i have a MANUAL 5SPEED 1990 sx seca 1.6 AE 93 4A-GE with axle-642 trans C52 tires are 185/60R14,
My issue is that the motor is revving at 3400 while at 100kph, sounds like it is way too high.
i have a mate with a 4door hatch corolla with the same engine and axle /trans codes but with 195/50R15 tires and his car rus 3000RPM at 100kph
i have made a comparison of the two tire sizes on a tire calculator and there is a minute difference in tire diameter so the revs should be the same.
when i bought the car the guy said it was not the original motor, but it is a 4A-GE engine
however he did not mention the gearbox
does anybody have an idea what might be going on??
is there another gearbox out of another model that has different ratios that may have been fitted???
any help will be appreciated, thanks
