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.

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.

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?

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 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.

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).

      Mistakes were made, my R34 Story

      I mean, I can confirm the TPS is at 100%.... I can confirm when we installed the TB and setup the cable that the TB was indeed fully open at max pedal travel.. the same 'curve' (WRT MAP vs MAP) existed with the previous setup/TB/manifold as well... No, we did not do a run with no intake connected. I would love to go back in time to do such a run to rule out the intake. It would have also been good to do a run with the airbox lid off. There's a test there where increased IAT vs more available air could be a positive tradeoff. I remember taking the lid off my R34 Turbo setup back in the day and noticing a monster increase, even if IAT's did go up. Could be similar. Hard to test unless I find a very deserted road.

      That's actually encouraging to be honest. my motor was rebuild many years ago but it's probably done less than 30,000kms and fucc all limiter or drift, majority street / drag / roll racing. It'll be fine 💪🏼 I don't even have lines or a can for the cam breathers installed yet, there is zero oil residue or splatter on or around them, it drives beautifully so it seems healthy. Just a ticky lifter, yet they're almost brand new oem genuine Nissan and haven't done many kms at all...

      Have you confirmed the throttle body goes to WOT (and stays there) during the run?

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      I'm having a problem. I think it was mentioned above somewhere but can't see it.  I'm stuck in the cycle of, sand, filler, low spot again, put filler, sand, low spot again, now i put filler again and a thicker portion which seems to have helped but I got low spots in other areas. In the image. Circled in red thats where the original low spot was and the shape is the same as the red out line. I've more or less fixed that (still low spot up the top but now I have low spots where the green circled part is.  Is likely the issue that I didn't start with a course sand paper? I sanded the filler with 240 to reduce the risk of not going to far but maybe the issue is that I'm only taking off enough material to remove some of the filler but not the high spots. I now started sanding with 120 and I think I'm seeing a difference. I did fix one dent the other 2 are f**ked and seems like I made another low spot which is indicated by the furthest green circle on the left handside. Any thoughts and solutions?   Also second image. All of these rock chips, can they be filled in with primer or do i need to fill them all with filler/putty? So many rock chips on mine lol.

      Well, I had an Edward Lee's special edition odo windback car/motor with a RB25DET S2 and I put down 372kW with a good amount of track abuse for 1.5 years before the ring lands decided it didn't want to stick around anymore 🥲 But probably didn't help I kept on smashing try limiter on the track and a few skid pans.
