unless they are a drastically different size it shouldn't be affected much. maybe a new speed sensor is in order.

maybe he should let us know any mods he has done to the drive train of the car, wheel sizes, differential, and any other modification that isn't engine related to help him out.

I agree with that what mods have you done to your car? I saw 1JZ so I am going for a yes on the mods. Cahnged out the tach or anything on the drivetrain?

I should have given you more info. I have a 1j but everything has been working fine for a year or so since it was swapped. I havent done any recent mods. It just stopped working recently.
