Does anybody know how high the rpm's are on a jdm h22a when cruising at about 65?

It's in a civic hatchback if that makes any difference. i just want to know so i don't get so bugged on highways if i get the car. how about cruising at 70-75?Does anybody know how high the rpm's are on a jdm h22a when cruising at about 65?
It's over 3000. Big difference from a stock civic. 75mph its more like 3600.Does anybody know how high the rpm's are on a jdm h22a when cruising at about 65?
buy a tachometer?



doesn't matter really right? because the rpm on the H22 would be the same as your original D15/16 motor.
