Thanks, thats exactally what I was looking for. What years? Nick

Thats the turbo ones. FC n/a ones are 460cc. I used to have a link to a thread that said year flow rates/impedance but I lost it long ago.

Check rx7 message boards.

Also, the FC earlier years were low impedance. It was only the later years that were high impedance. I think the turning point was 1988 IIRC

I found this: http://www.msefi.com/msinfo/manual/rotary.htm#injspecs but it doesn't say anything about the impedance or years. Nick

there you go. I found the info on rx7club.com some number of years back.

The people on rx7club are not helpful at all! http://www.rx7club.com/showthread.php?t=446518

They are from the late series 4 rx7 turbos. The model number is 195500-1370. They fit straight into the fuel rail, but the inlet manifold needs to be bored out maybe 1/2mm-1mm. I think they are 14ohms (high impedance).

Ouch man. That sucks. I have never posted on there, but I can say from experience that just about all rx7 owners are a cocky bunch.

**KiNg MaRtY** · 7-25-05, 15:27

wow, bunch of azzholes there

**04ProbeGT** · 7-28-05, 23:11

there not azzholes there just made cuz to own an rx7 it takes money to keep running and no mater how much you put into them thay always have somthing wrong with them. sold all of my rx7 because of this problem.

You shouldnt have to bore out the fuel rail to install the injectors in a F2. Only the FE3's rail is too small.

Oh the injectors are red-tops if that helps.

You dont have to bore the fuel rail. You have to bore the inlet manifold where the injector seats (The "squirter" side of the 550cc injector is about 1/2mm diameter larger than the 330cc).

Damn near every injector I've tried, including stock F2 injectors wont fit into the fuel rail, but fit into the intake manifold. The little bungs in the rail need to be widened by 1mm. On the FE3 that is.

**black_tx5** · 7-30-05, 9:30

anarchyx34: can you use the f2t fuel rail on the fe engine? If not how will you get larger capacity injectors in there? Custom rail, or will you bore it out?

**anarchyx34** · 7-30-05, 9:48

I'm going to bore mine out. It's not a big deal. Just 1mm and it can be done quickly and easily on a drill press. Then you have a zillion different injectors to choose from.
