Even with a decent fbody frame to start with, you would probably buy an old gn motor that needs work to be restored back to new which cost $$$. Then everything that has to do with the tta is expensive as hell. 725 bucks for a freakin wiring harness. And it don't get cheaper either and chances are you will need to fabricate some things. If your willing to spend the dough then go for the hybrid. (I did and its almost done but $$$ went into it). Otherwise, just find a 89 TTA and fix it up and you will probably spend less. Either way your gonna have a fun car but please finish it.
