I never really understood the way they did the 2JZ motors turbo design. I understand the setup working like it does. but why not do 2 mid-size turbos independent of each other like they do on most v8s? they will only put down 15-20lbs of boost but the air mass they move would be equal to or greater than 1 big one. Then boost up the numbers and move more air and its out doing the single big turbo being fed by the smaller one.... or is my theory incorrect???
