I don't the think secondaries are opening up all the way. How are they operated cause there is no wires or any thing going to the little plungers on the side of the engine?

Also what are somethings i could to increase horsepower?

Thanks

The aux. port actuators on a GSL-SE function like the ones found on non-turbo series 4 cars: off exhaust pressure. Here's a link that goes over testing them: http://www.aaroncake.net/RX-7/6porttest.htm

Ways to improve power include exhaust modifications, programmable computers, forced induction, nitrous oxide, etc...

Is them seizing kind of common?

Yeah, it's not uncommon to find actuators seized. Sometimes it's just the actuators themselves, which can be unstuck with some spray penetrant. But if the sleeves inside the block are sticking, the LIM has to come off so they can be cleaned.
