I have an 87 mkiii and I just bought an 89 mkiii because the body on the 87 was in really bad condition. Both are turbo 5spd and stock, but for some reason, my 87 seems to pull a lot harder and runs smoother than the 89. The only difference is that the clutch on the 89 is about to give out and that the 87 has a cone for the turbo. The 87 also has a rebuilt engine and the 89 only has 120k on it. Should this really make that much of a difference in how the two cars drive?
