I have a 3000gt sl I was wanting to know if the upper and lower intake maifold from a vr4 would give my sl n/a motor more hp

No. The lower intake is the same, and you will actually cost yourself some power with the VR4 upper intake.

The NA upper intake has the VICS system. It essentially makes it to where the upper intake has two different sets of runners and the valve switches over at certain RPM points. Without that, your car will be unbearably slow off the start.

Intake, downpipe, test pipe.

The intake won't help power all that much, but it makes the car sound throatier.
