I know the guy that originally designed the kits to put 5.0, LSX, and early 4.6 V8's into the Monster Miata's (Nick Manning).
Knowing how difficult that was, I would be extremely interested to see how anyone crammed a 5.4 GT500 motor in a Miata.
That would have rendered the Miata completely useless for the amount of weight and power in the front, and the severe lack of traction out back.
Waiting on pics.
OP has this amazing car collection and wild builds but miraculously can't manage to find one picture to show anybody. Maybe they don't have cameras in Yemen?
Already did a FD with a cobra 03/04 drivetrain, didn't like it.
Also did a Miata with a gt500 drivetrain and that was wasn't fun to drive.
My vote would be for a F100 with an ecoboost
I smell a lonely fella.
Ya my life sucks and I have no friends and I live with my mommy in her basement.
