Whats the difference between a 89 gtst and 92 gtst?

I posted this in another forum but no one could help

Um, the build plate will be different?

Blue dials on series 1, grey on series 2.

Surround around cd player etcis smooth black on s1, textured grey on s2.

Headlights are different.

Clear indicators on s1, orange on s2.

Apparently the engines are slightly different but i dont know how.

Maybe post this is the general forum or the skyline and other spec vehicle forum, noone really comes is here.

The '89 interior trim is grey, later models is black (or VERY dark grey), some of the '89 models came without climate control (pretty sure it's standard on later).

Engines & ECU's (have compared maps myself) are the same as with all the other running gear AFAIK.
