My 87 gt also has the 1.9L EFI HO engine, same as 88, 89, and 90, but the heads are different, that could account for the difference in horsepower. It is true that the 87 had 115 hp, but I don´t know about the other years. The front bumber cover on the 87 is designed differently than the other years but I can´t confirm a twenty pound difference in weight (seems like that estimate is too high) The 87 escort gt is a very strange car indeed. There are many parts on it that are different from earlier cars and later cars. In fact I think that in time, they may become a very rare car, I have noticed that it is harder to find parts for it in the junkyard. Also the ford dealership has stopped making some of the parts for it. For example there is some sort of emissions pipe that runs down from the intake and connects to the end of the header. When I asked the dealership if they had a new one, they told me that it didn´t exist, they couldn´t find it in any of there books. I also tried to get a new grill, but they stopped making them and the guy told me that there were only 3 left in dealer stock in the ENTIRE COUNTRY! And good luck finding one in a junkyard. Anyway I think I´m done rambling now. (sorry bout that)
