How can you compare your Turbo K motor to the N/A K motors?? If we wanted to compare apples with apples we'd have like 20 different lists. Its not gonna happen.
KE70s came with 4As, so what if he bolted a twincam 16v head to it? No ones stopping you bolting on some NAWZ or some other power adder. As for the supercharger...well you're running a turbo aren't you?
