i have a 97 gsr and im having a problem. When i drive my car it rev alot higher than normal. When im on the high way going 60 mph on 5th gear my rpm is at 3000. And when i go about 80 it rev at about 4400 in 5th gear something is wrong. Dont like driving like this. Please help? No check engine.

 

that's slightly off.

my 97 GS-R runs at 4000 at 80, exactly.

What mods do you have?

 

my car is all stock no mods. check out Portflow Valvetrain. The inner valve spring is all you need.

 

3000 going 60 in 5th is exactly right for a GSR tranny. you should be at 4000 sharp at 80 mph, 4400 would be a b16 tranny.

 

Is the clutch slipping or is the tachometer and/or speedometer reading incorrectly?

 

Everything is working fine. just rev too high.
