hi. im just wondering if anyone has or knows where there might be some pics of the sard 550 side feed injector collars. im thinking of getting some 550ss injectors but the collars are about $40ea. i was thinking if they could be matched up with another local setup available at the good ol wreckers perhaps.

:D Dave.

just buy a set of nismo 740cc injectors.

straight fit for the RB25... and if your running a PFC, no idle problems at all.

thats what im running and the idle is better than what it was factory IMO.

just make sure your oxy sensor is working :P

Try Dyson Rotary. I bought 3 off him, and another 3 off a guy on the Ausrotary forum.

If you want no problems and are willing to part with $1k or so, get the Nismo's. If you don't mind a challenge, have access to a lathe, and want to save a lot of coin, go the 20B's. Just had mine cleaned and flowed, and they have an excellent spray pattern.

Here is a pic of a 13B injector (left), 20B (centre), not sure of the injector on the right, but it looks similar to a standard RB25.

The 13B is a standard pintle type injector, the 20B is the same but has an aluminium cone on the tip to atomise the spray better. So i don't believe the spray patterns are any different to other pintle injectors.

    • I now seem to be limited in power due to my rev limit/hydraulic lifters in my built RB25. I'm looking into converting over to Tomei solid lifters. Question for anyone that has done the conversion. I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  I don't know where I got this idea, as so far I see no mention of this in any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must be missing something? 
    • I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday. Now for some reason I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  But I see no mention of this on any of the Tomei documentation.

    • BRUH, one of the biggest mistakes of my life..... and i've had plenty ;[)
    • @Murray_Calavera iam just considering options 🙂 of course it is very expensive so that why i ask here 🙂  @joshuaho96 I looked at that GCG hybrid(i remember looking at it few weeks before) So this is "that" hybrid where i send them my turbo and they upgrade the inside to Garrett stuff and then they send it back. It cost around 1200-1300 USD which is FAR cheaper than the HKS and it is what iam looking for(i just do not have experience like this...to send something off to "upgrade" ) @tylink720 that is like 150 USD turbo no? 😄 I dont think i have the "ease on my mind" with this kind of turbo. I just put over 7000k USD to "LINK" up my engine...dont want to blow it up with cheap turbo 😄     EDIT: https://www.cj-motor.com/gcg-turbo-charger-for-nissan-rb20det-rb25det-high?srsltid=AfmBOooVeOZ6CZ6r1AIv5m-KPaa6BvudIPJTY8LW78khkd-gQlsaCht9 I looked at this and it seems ok? It is that CGC hybrid and it costs around 1250 USD (with back shipping). Do any of you have experience with this hybrid on NEO turbo? I quickly look thru the forum/web and it seems very good.
