No probs it's just one of those Supra Myths that pops up now and again and probably goes back to someone did the 1.5Jz thing and gained some throttle/engine response and thought it was "better" ;)

Someone posted actual flow bench figures on SF awhile back and it doesn't support your argument other than velocity is up on the 1J ports so it "may" be a slightly better responding engine at lower rpm.
