I was just wondering if the j-spec turbo motors came with the 5/6th ports to the combustion chambers. because i dont remember seeing any actuators located by my ACV or intake manifold. Thanks!

 

Turbo motors by default are of the 4-port design. This is a design better suited for forced induction application, or so I am told.

 

All factory turbo rotaries are 4-port. The 6-port design was intendd to increase horsepower on the top end without sacrificing bottom end torque. The 6-port design has little/no use on a forced induction application.
