Injectors identification

My neighbor gave me 4 Nippon Denso injectors with blue tops on them. I have an 89TII and I'm not sure if these have the kind of flow required in the car. I don't have any mods done to the car, and I doubt that I will any time soon.

The reason I ask, is because I just got a j-spec engine and I was gonna clean the injectors to try and avoid the flooding problem. I asked my neighbor where to get injectors cleaned, and he just went into his garage, produced 4 injectors and said 'Here'.

Is there any way for me to tell what they are?

Thanks

Pictures?? Maybe Manufacturer info-like engraved MOdel numbers ??

Non-turbos have different CC injector flow rates than Turbos.

I'll tell you one thing, I sure as hell wouldn't put them in if you have no way of knowing the flow rates.

Do they look purple? I believe that the stock FC 550cc injectors are purple that's why. I can't remember. The 850cc's from the FD are red for future reference.

Also, measure the resistance on them to see if they are high or low impedance injectors...unless you're running a haltech

Is there the smallest possibility that the number is 195500-1370 instead of -1970?? The -1370 area 550's and when new have purple tops.

There is also a locating tab where the electrical plug goes. Is it centered or off set in relationship to where the electrical plug goes?? The tab being in the center means they are low impedence. Offset high impedence. Are the electrical receptacle rectangular or oval in shape?

Wow Hailers...that's some good information. I didn't know about the tab being off center as high.

But my stock 550cc injectors for my FD have the tab in the center, and they're classified as "high impedance". 13 ohms I believe. The receptacle is oval in shape. What does that mean?

the tab only seems to apply to the square plugs. the oval ones are all high impedance

One of the four Injectors:

The connector on the injectors:

When I hooked a couple of them up to a multi-meter. I got about 15Ohms of resistance. Is that a reasonable number, or is my meter messed up?

Well the 1988 FSM lists 12~16 Ohms as being in spec, so you should be fine. Unless you have some other reason to suspect that your meter is bad.....

Your resistance is fine. Too bad your pics didn't come out though...

I still don't know what kind of flow these injectors have. I've done searches on the net, and haven't been able to find anything on this particular part #195500-1970. They didn't come from an RX-7. They came from the garage of a Ford Mechanic.

Maybe I'll call Nippon Denso.

they didn't say anything, but the local injector cleaner type person said 52ml/min.

i guess the injectors were from a pinto or something

Kia Sephia
Gasoline
Resistance - 13,5 to 16,5
Pressure (bar) - 3,0
Flow(ml) min & max 26,0 32,0

I wouldn't touch 'em with a 10 foot pole!
