help identifying injector size

[95zenki man]

picked these up last night for my s13 and something is telling me they arnt what i was told.


I was told they are 660's (he didnt know the brand or anything) The only markings on them are " made in japan" around the bottom of the top red part and the stock s13 clips plug right into them.

can anyone confirm that they are 660's or do i need to go ask for some money back?



any help would be nice! i just have a bad feeling that i didn't get what i was told.

from what ive learned the only way to tell what injectors you have is to actually have them tested. Apparently the 550 to 740cc all have the same color and have no real identification what cc they have, atleast for the 240sx

You can ask him for a flow chart if avail. Otherwise you have to get them tested.
