Just wondered if anyone knows what these injectors are? Was told they were 550cc when I bought the car they have different plugs soldered on

 

 

This might help http://z32.wikispaces.com/Fuel+Injector probably the new type hence the plug might be different

Cheers mate they look very much like the Nismo 555's

Here you go they are early type 555 later connectors are more oval.
