I currently own a 4agte sprinter, the motor is originally a 4agze with turbo and exhaust manifold. I am just looking at ways for power gains and better drivablility. As I have been told the small port head is ideal for this setup(jdm 4age from levin/trueno, correct me if im wrong)
What are the specific gains in using the 16v head on a 4agze block? Is the small port ideal for this head conversion or are there other ways to fit/modify the big port? Does the head bolt straight on, and will it require any modifications to the inlet manifold?
