I would have to disagree with you. DSM aka Diamond Star Motors was a Mitsubishi/Chrysler venture which ended in 1993 according to articles. Some 95 Eclipse/Talon ended up with DSM badges/stickers and the rest of the 95-99 ended up with just Mitsubishi badges/stickers. So no "DSM" did not stop making the 4g63t motor in 1999. DSM ended years before 1999. I had to correct your bit of false information there. In reality, technically DSM ended in the 1g's (90-94) some of it got carried over to some 95's. Now there's reason why 2g's are considered DSM's but hell this subject has been beat down for years... no need to get into it.
