I just bought a 1990 Celica GT-S. It has a five speed and driving300 RPM seems like the high side of the normal range. How did you
home I saw it was running around 3000 RPM between 65-70 mph. This is
a much higher RPM than I have seen in other Toyotas I have owned. The speedometer was dead on accurate on its speed. Should I consider
this normal for this car?
verify that the speedometer was dead on accurate at 65 MPH? I assume
you were if 5th gear? Are the transmission and differential original
Hmmm...that's the correct size....
I thought maybe they were replaced with a different sized tire the would
throw the speedo off, but that is the proper size...
My dad has a 86 ST162 that runs at 3500rpm on the highway, this is normal for the cars with the GE motor. he has changed the motor and transaxle to a mid 90's JDM spec but before that it ran at about 3000rpm. if it's running well you should get close to 30mpg cruising on the highway with that RPM.
While I think about it. The Celica normally have a 4.1:1 diff and a 0.86:1 5th gear. for a 205/50-15 tyre the outside circumference is 72.5 in which is ~874 revs/mile and you do about a mile per minute on the highway. so 874 x 4.1 x 0.86 = 3081RPM. so the 3000rpm indicated is fine.
