a little fishy is right. Not to be a dick but why would someone trade a "12sec" AWD DSM for a ( I don't know what your car runs) but probably a 14 sec honda. And he's giving you a free FWD tranny , I don't know much about AWD but I'm pretty sure a FWD tranny would not work.

22psi is pushing a 16g kinda hard. I've heard of people pushing a little higher but on race gas and not to often.
