Hey Guys, Need help. Pulled one injector from the rail of a modified Z32 after removing the plenum (what fun that was). It is grey topped with a dark green fuel screen, says made in japan on that same green fuel screen, has 0011 and also 1Y27D on the top grey collar. Is there any way to tell what size the injectors are? This is engine number three and there is some question whether Nissan swithched supposed 555's from the 2nd engine to the third when they installed it. I'm replacing all six injectors and would like to keep it the same as it was so I don't have to reprogram or replace the ecu. Please advise as I have looked at all the threads about injectors and still can't figure it out. Thanks!!!!
