A Jun III cam or Toda Spec C is one of the targetted cams...however, would it be more logical, at Phase I, to modify the head/manifold/TB to allow for more 'breather' for the car i.e. ITR head, manifold, TB...than the stock GSR (with two butterfly)...then at Phase II, we will fix in the Jun/Toda cam kit....wouldn;t this ensure better life span of the engine..
