But, you're not installing the US-spec engine, you're installing the JDM-spec engine and calling it the same as the USDM plus allowed modifications. To do this you have to violate the stock intake manifold rule, because the JDM and USDM manifolds aren't the same. It seems pretty clear to me, you need to specifically allow the JDM motor or remove the intake manifold/throttle body number rules to make this legal.
