Not sure why exactly, but the GTs can be up to 300lbs *heavier* than the equivlent 2m6/Formula.
My Formulas are both faster (when they were stock) than any stock GT I've ever driven. (87s and 88s only, all 4 cars with getrags.)
The 4sp supposedly is actually a little *faster* (not sure why, the 5-speed has slightly tighter ratios 1-4 than the 4speed even...) Dunno, never driven one. The getrag's ratios aren't perfect, especially first, it's WAY too short. should be much closer to second. Anyway.
Best!
Ben.
