Any idea what injectors these are?
 

So I bought some injectors a while ago that were used. I was told they are 720cc's and 1600cc's which I wanted.

Part number on the primarys is:
125500-0830

part number on the secondary injectors:
(192 this number is listed above the others on the injector)
280180842

Here is the best picture I have of them, note they are between the intake and the radiator hose. The injectors with the black bodies are the secondaries, the silver bodied injectors are the primaries:

The reason I ask is when putting a base tune in, for 720/1600's the car leaned out indicating wrong settings. When changed to a map for 550cc injectors the car ran fine. I just want to know what kind of injectors I have and confirm my 1600's are actually 1600's.

thanks

I would suggest having them cleaned/flow balanced to figure out what you have. Since people have injectors enlarged all the time, sometime simply having the P/N may not tell you exactly what you have.

no matter what someone tells you or what it says the only way is to have them flow tested if they are really 720/1600 then they need a cleaning and to be tested. gl with it looks like fun
