I have a s13 but if I remember right as far as I know there is a variable resister on the back of the tach and you can get that pretty well set correctly (won't be perfect). As far as the speedo goes I had mine sent off to LS Auto and for like $115 (included shipping back) they took care of that and seems to be very acurate. They can do the Tachs too i think if you don't want to mess with it.
