faaaarrrk thats alot of gas
i think in outright drag aplications both engines are equal
if your after 600rwhp on a std bottom end the 2jz cant be beaten
like the green subzero supra made 998rwhp
and my skyline made 1068rwhp
you could also put that down to wheelspin but are both 3 litre engines
i think the supra run a 9.2 at that power level ova 150mph
ive run a 9.7 @ 141mph with 597rwhp and no gas as im still getting used to the car
who cares if one head flows better std if the other head could possibly be ported further
at the end of the day the man with the deepest pockets wins
which is definately not me as im a peasant
