Diamond star motors no longer exists that is why. It was when Diamler Chryslter owned Mitsu. DSM's technicaly stopped in like 95 or somewhere around there but since they still used the same 4g63 then they stilled called them DSM's. Then in 2000 they got rid of all of the old mitsu stuff shared by Diamler Chrysler hence 2000+ are not considered DSM's.
By all means still come out casue the more the marrier, not trying to put down the 3g's.
Damn i got beat to a response
