does my 86 na rx7 have extra vaccum solenoids or do i have to buy new ones. im trying to convert to electronic ports but i need a vaccum solenoid it says can be found on my engine only mine are all hooked up and i dont think i can just take one away. so do i need to buy a new one. and what hose goes to the 6 ports themselves(vaccum) is it the hose from the split air pipe?(big one or little one)? thanks

yeah youll need to buy one unless you did emissions removal.

The 6 ports run off of exhaust back pressure on series 4's, not vacuum... It's the small tube on the split air pipe that goes to the port actuators. Any vacuum solenoid you take off the engine will take something away from the engine. There are no "extra" vacuum solenoids. If you want to do emissions removal, then you don't necessarily need those solenoids, but that's up to you.
