Default sr20 370cc injectors install question.

I ended up moding the sr20 injectors today after finding out my yellow top injectors would not be a straght drop in. So I moded the injector plugs but the stock rs plug would not go straght on, I had to turn the plug upside down. Here is a pic:



I haven't started it up because I need a new starter. Do you think this would be a problem. People that have the sr20 370cc injectors please reply.. I really need some feedback.

the injectors are just a switch arent they? so i dont think it will matter which way you have them hooked up but i am not positive, hopefully someone more educated can chime in.

Ha, I didnt even read the post, I just saw that you had yellow top injectors that might be up for grabs.

And no, it will not matter. You can wire the injectors either way and they will work. As long as you have your 12v and ground it should be fine.

the impedence of the injector does matter but I don't know what sr's are and the stock rs's are. I see them for sale on ebay alot with resistors to change voltage

The JDM Silvia injectors will work as a drop-in replacement.

So they have the same minimum turn on as the stock injectors? 120ms? What cc sizes do they come in?

the s13/s14 silvia had 370cc injectors, and the s15 had 440's. you can get 570's, 660's etc from places like nismo and other nissan places. the silvia is the civic of japan, so they're made by everyone in pretty much every size.

I had them in my car years ago. I used them in conjunction with the Apexi S-AFC and had to lean them out at idle and off-boost conditions. I wouldn't try to run them with only the stock ECU. Also, the connectors will not accept the stock harness plugs and I made some adapters using some GM harness fittings I found at Pep Boys. They do, however, plug right into the fuel rail.

I'm sure I tried, but I remember that the harness adapter wouldn't fit over the 370cc adapter. Are you worried? The injectors do not care which wire carries the load - as stated earlier in this thread, they are simply a switch. If it's working, great.

Update.... The injectors are still not shooting fuel. So, I'm going to cut off the rest of the plug. This is so the stock harness with fit right on to the injector with nothing blocking it.

I'm doing this to avoid cutting the stock harness and soildering new plugs on.

I have them in my car, I went to the salvage yard and got Sentra injector harness so that I could do a clean install. The salvage yard even gave it to me for free, just cut the four connectors off for me. I then dissassembled the subaru ones removing the wires from the connectors still with the pins sodered on. I then disassembled the Nissan ones and stuck the subaru wires and their pins in. Worked great for me, no cutting and can go back to stock easy while having a factory look.
