your going to have to do everything custom man. anything is possible its just up to you to figure out how. theres a guy on here that stuck a s2k cluster in a 6th gen. it can be done. just lots of work. i will tell you that the 3rd gen ludes have a fairly simmilar shape as the eg. not sure if it will fit but you can try. just make sure you get one from a 90-91 si as the 88-89 had a cable fed speedo. the 90-91 was a electrical speedo like the 5th gen civic.
