In addition, the 2.0T is almost 3300 lbs. Much heavier than the worst case scenario for the FT
Also, tuning potential is independent of turbo vs. NA -- a turbo motor doesn't intrinsically have a better tuning potential -- the turbo may be already be at its highest reliable boost, the NA may be detuned for economy reasons. There are lots of factors involved. That said, the NA has the advantage all other things being equal since you can always turbo it and pop it past the other turbo motor in terms of HP and torque.

Turning up the boost aside, turbod cars stand to make much larger gains with simple bolt ons. Thats what Jeff is saying, that if you put $1000 into both the FT-86 and the Gen, the Gen would gain a significant advantage. Stock for stock you may be right that the performance would be very close.
