Auxillary Port Valve Trouble

[FerociousP]

If anyone knows any tips to help with the auxillary port system on an '86 13B N/A I could use some help.

When I hook them up to a low pressure air source they open and close but when put to the exhaust there is nothing. I have read many articles on how the system should work but have no idea how to diagnose what part could be wrong. My air pump seems to be working and the sillinoids click and make noise but I'm still getting nothing.

I ended disconnecting them from the exhaust and they now open but stay open and its causing low end power loss. I autocross this car as well as drive it daily and would like to have that power.

Also I recently bought an engine from a guy in chicago who said it was from a '91 RX7. I have heard that this engine might have a little more stock hp and was wondering one if there was a way to tell from looking at the engine if it is from a '91 and two if it will fit/work with my '86 car.
