Is a port and polish when you bore out the valves and smooth it out? That's my guess. :P Are there any components on the motor, that if removed or replaced by an aftermarket part, would free up some power? A friend told me that the crossover pipe in a generation of nissan maximas is freaky shaped, and it is very restrictive in exhaust flow. Anything like that on the lude?
