Am I the only on that us thinking that I could hack out the firewall. Move the drivers seat to the back. Put some sort if v6 in it with boost. Weld back in a new fire wall using somthing similar to those found in a ford van to cover the motor. Then take a ford 9 inch from a pro four and transplant it with the four link and coilovers.
Probably need to augment the cooling somehow with a bigger Ra and a big oil cooler (fc rx7 cooler)
This is just my first plan. I still need to work out the trans but I am sure I can figure that out.
Speaking of that maybe take a v6 from a Camaro with the manual box as a unit. That would simplify things.
