There is a chassis code...

95-99 Mitsubishi Eclipse is a D31

In there they have a list of cars... ranging from
90-96 Toyota MR2 which is SW20 to 89-98 Nissan 300ZX being a Z32 to 89-94 Nissan 240sx being the S13.

There are Eclipse's in Japan. There's 1g's and 2g's. Somewhere I had pictures of where they took an 420a based Eclipse and swapped an Evo 8 motor in it and did the Evo 8 brakes and Steering Wheel.

You might find pictures every so often in a OPTION magazine. But yes they are over there.
