Cost of buidling a 2JZ> "M" Anything
Availability of parts for a 2jz>"M" Anything

Supras are somewhat easy to get POWER out of, they do cost money, but its not too bad. with $9000-10,000(you do the labor) you can make 1200-1400 WHP, thats WHEEL HORSE POWER, not FLYWHEEL HORSE POWER.

HANDS DOWN the Supra motor is the BEST IMPORT MOTOR in terms of aftermarket support, reliability, power out put, availability of parts, ease to work on. They are simple motors, i put Turbo Daves Cylinder head together when he was busy , i had never touched a toyota before, but they ahd a similar layout to a honda head so it was easy.

they OWN all IMHO

still a nice BMW
