Diamond Star Motors (DSM)

This is a bittersweet page in my life and on the website.  Diamond Star Motors was purchased by Mitsubishi a while back and they had a factory in Normal, Illinois (I don't know if this is the case; I guess I could have googled that pretty easily).  I would say that this was Mitsubishi's finer moments due to the popularity of the 4G63 motor, Lancer and 3000 GT.  They were making motors for Hyundai, Eagle and Plymouth Chrysler during the 90's.

The first car I purchased with my paper route/cleaning aunt's apartment buildings was a 1992 Mitsubishi Eclipse GST 5 - Speed (FWD Turbo).  I learned how to drive manual (or 'standard transmission' if you are British) and also taught my brother as well.  

Admittedly, I have a bad habit of taking things apart.  The engine (4G63T) was leaking oil through an exhaust valve guide.  I decided to fix it/rebuild the bottom end while fixing the cylinder head...this was my first exposure of being a 'car mechanic'.  All I can say is that the rebuild failed miserably as the bottom end spun a bearing, but I eventually rebuilt it again successfully.  They say, 'it's better to have tried and failed than not have tried at all' ... I suppose that quote makes sense if you are trying to gain experience points while increasing personal suffering.

Anyway, I then purchased a 1995 Eclipse GST followed by a 1996 Eclipse GST (AWD turbo).  I have some pictures of the rebuild and random things I did with the GST.  This was a labor of love but also a huge time suck.  Eventually the oil pump failed on the rebuilt motor which caused it to seize :( I eventually bit the bullet and purchased a newer car that had a similar 'feel': the 2014 Genesis Coupe (RWD, 2.0L Turbocharged).  It just made sense to buy a car rather than spending the time and money on a 20 year old car.

p.s.  This is why my brother calls me an orange neck.

GENESIS

This is the car that usurped the DSM.  I picked this car up from Maryland and drove it back to the great state of Iowa.  East coast cars tend to be cheaper (depending on make) than in the Midwest.  I never thought I would buy a Korean car although it is from the motherland.  Hyundai had a terrible reputation in the 90's early millennium.  However, this car met the criterion that I had for a newer car; it was RWD with Limited Slip Differential, turbocharged and 4-cylinder for better fuel economy.  

With that said, I still miss the DSM.  It had more of an 'analog' feel rather than the current computer-controlled Genesis.  The Genesis uses electric power steering; whats up with that?  Also, if I want to tune the car, I have to either break the bank with a Haltech or flash the ECU.  In the DSM, I had a complete stand alone chip/controller/software for a third of the price of a Haltech.  While I'm still griping, let me say they didn't offer a moonroof on the R-Spec model either.  These are what I call first world problems <- funny at first, but it's an indictment on our society (including myself).
