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?

I'd say the rebuild and cone is what makes it pull harder. The clutch shouldn't make much difference unless you're mainly launching or if it's slipping/going out.

Ideal, he's asking about the cars, not the trannies, lol...

There are no R154 differences though, you are right.

so i thought he meant the trannies...

Do the pre 89 and post 89 run the same gear ratio in the rear end? I tend to *not* remember details that don't affect my '89. :)

87-88 Turbo have 3.91:1 gearing
89-92 Turbo have 3.73:1 gearing

They feel very similar though, from my experience.
