I havent heard about the stop making of the 6 for a 5 speed. I have to disagree that if they went to a 5spd it would be faster simply because the gears would be wider and would take longer to get back into the higher lift cams. The 6spd doesnt even hit it in every gear but its very close.

Secondly Toyota is comming out with a wagon (in pair with Pontiac WHAT WERE THEY THINKING!!??) that will have the same 180HP and 6spd combo as the GT-S. If they were having problems I dont think they would expand the line up of the combo...just my opinion.
