Everytime i see a motor or any other JDM parts for that matter, they always have REAL LOW claimed milage...How do people know whats really on the motor? how do they know there isnt 90k on a motor instead of 30k? I know japan is a small island and all so that explains part of it but it always makes me laugh a little when i see "b18C with 30k miles"...How the **** do they know (unless it came with the cluster)
