RX7 injectors

[JimX]

Sorry to dig up an old thread but it's all relevant I'm after the same set of plugs, but I can't seem to find any. I tried Coventry's on someone else's advice but they don't have any. I also tried ringing a couple of Mazda wreckers but they had none either.

Does anyone know where I can get them from in Sydney and roughly how much I should be paying? I'll try a few more wreckers in the meantime.

Edit: I'm going to try Findapart.com.au and see what happens.

They are the same as commodore injectors as i said in my post.

Sorry, I missed that I will try some Commodore wreckers too.

What sort of money do you guys pay for 13b 550cc injectors? Some dudes want HEAPS for them like over $100 second hand!

[JimX]

Around $80 each is around average I guess. $100 isn't too bad. $50 is the "buy it now" price.

Update on my situation: I found a Commodore wrecker that has some plugs (for $5 each) but I didn't have time to get around there today. Maybe next week.

lukevl, RX Engineering gave me the price of $100 cleaned, flow tested and serviced or $165 new.

[lukevl]

Yeah $100 is okay when they've had that done. But I've had guys say like $120 straight out of a dirty old wankel from Japan

I bought a set about a year ago for $125. These were flow checked and they were also a FLOW MATCHED SET of six, which is probably worth a few extra dollars.

plugs are oval. Can't buy them anywhere and cost $30 each. Don't waste time and money trying to get the correct size. Use 2 female pin. Clip it to the wiring loom and shaft it in. Use high temp silicon to prevent water entering.

Too easy

[JimX]

So they're not the same as Commodore plugs? Where do you get the "2 female pins" from? When I had a look a few days ago it seemed the pins on my clip are already approximately the right size and shape, just the clip was stopping them going on. So if I just remove the old clip and push the pins in, then silicon it up, that should work?

[sil21jun]

I did mine with pins I bought from Mitre10. I am not sure if the plugs are the same as Commondore ones. Use another set of wires approximately 3" long. Connect it to the new female pins. Test the resistance between the new terminals. If ok, squeeze silicon inside the injector socket and wait for it to dry completely. Connect the 3" long wire to the standard injector loom. You can choose to remove the old injectors plug or hide it somewhere. Preferrably water prove it in a tiny plastic bag. It is important to test the connectivity or it will be too messy to clear those silicon out of the way! Good luck

Unfortunately there are a few different plugs, series 4 injectors are the same as GTR and rb20 ones, the series 5 ones are different, ive been told they may be the same as rb25 ones but i cant be sure they look similar on the fuel rail, anyone have any pics of some or some for sale.  

Unfortunately the places im sure will have some are on holidays till the 6th so i may have to wait unless i can find some.

I doubt they are the same as RB25. I have seen those rx7 series 5 injectors. High impedance and top feed. If SR20 uses the same plugs as RB25 then they are not the same. The plug shape is slightly the same as the SARD 550cc injectors (oval). The 2 side grooves for the plug to slide in is slightly off tho.

This is the RX7 series 5 injectors

[Clint32]

There are plugs off other mazda engines that fit those injectors mine were off a B5 from memory

[Warpspeed]

Yes, Ford Laser 1.6 plugs fit perfectly, I know this for certain.

Mazda 323 plugs would be identical. Should be very easy to get as well.

[raist60]

They are the same as VN commodore injectors plugs (I dare say ive seen these plugs on a ****LOAD of injectors) i said that before.

[JimX]

Damn, I got off work early today and I forgot to go to the Commodore wrecker to see if they fit. I'll try to remember to go this weekend. My injectors look virtually the same as sil21jun's (but from that angle it's hard to tell if they're exactly the same).

The injector thats pictured has the commodore plug on it
