Im not an expert by any means but it sounds like you are running out of fuel in the combustion chamber (or lean) and setting off the cars knock sensor. It seems to me there are several fuel pumps available on ebay eluding to the fact that they were a weak component. be extremely careful "pinging" is extremely BAD for the pistons and block. keep out of hard boost until you solve issue.

Why dose my mazda 323 gtx over boost buzzer come on and boost cut

Sounds like the waste gate is having trouble. It could be what's called a "boost leak". the waste gate is most likely internal on a factory system. On the turbo, You'll see a small, vacuum pod looking thing with a linkage connected. Check to make sure the vacuum line/hose is properly connected and run that line to make sure it's not cracked some where.
Otherwise, it could be any coupler, connection on the pipes that carry the air from the turbo to the throttle body. Even a "loose clamp" can cause boost leaks. With over boost, it's most likely the waste gate.
Good luck. Hope ya find it.

1989 Mazda 323 gtx BG

Two things...
You should follow the pin numbers and not the color code.
Check online for a service manual from Japan or the USA for that car. We got many Mazda imports here and there should be a lot of books on Ebay that would have the electrical schematics for a 323 from the USA and Canada.
You are going to have to just buy a book and have it shipped to NZ.
