im abouts to swap a k20a2 into my o5 civic...and i want a cluster that has the rpm tach....i was just wondering how is the situation gonna work out with the new motor and the new cluster...is the odometer gonna use the original miles of the motor that i took the cluster from..or will it read how many miles is from the k20 swap...i just dont kno...anyone have an answer for me?

 

its going to read the mileage from the odo no matter how many miles your car has.
