Im about to upgrade my Injectors and am probably going to get Nismo 555cc items but have noticed that the Sard ones are a little cheaper even with the collars.

Would appreciate some honest opinions on which injectors you guys believe is "better" and your reasoning for that decision. Ive been told by slide that the Sards are only a single spray as opposed to the Nismo quad spray but im having trouble making up my mind on what to go for.

Thanks

Blue 700's (sard) are single spray, and the larger ones are dual spray... for RB26's at least

It's supposed to help with fuel atomisation or something, but i've been told that its really nothing to get excited about.

IMO for your general streeter, whatever fits your budget. Nismo's are easier to fit, Sard aren't... price is reflective of that IMO.

I know RB26's (twins sprays) you need new injector plugs too, or at least a mod... check the RB25 ones dont need that also

Maybe AFR's, but it wouldnt be huge (so little you would be hard pressed to pick it up i reckon)...

Maybe slightly better economy too, but i've really never seen some hard evidence here to back one or the other more favourably.

Everyone seems to be happy with the ones they have

I would go Nismo... ease of fitment. Thats just me.

Ive used them twice now... although i am taking the plunge soon and putting in Sards, well, im not putting them in myself this time i dont think actually.

The Nismo's i could easily do myself, i doubt the Sard's would be much more difficult however.

I think the price difference is less than $60 last time i looked so its nothing major out of $900-1k

My personal preference is Nismo. I've just seen what the shop I hang out at does, and most of the cars I've seen with Nismo injectors have had been able to run at a leaner idle, have had more consistant plug readings (color) across the set, and the used set we sent off to get flow tested were all with in 1cc of each other. I haven't seen any real bad things with the sards, it's just the few I have seen had to be run a little richer at idle than they normaly tune for, and the plugs looked a little different. Again, it's not that I've seen bad things with Sard, it's just I've been nothing but impressed with the Nismo's. I even paid for a set of new ones which are like $800 or so up here---which is saying something since I'm a cheap SOB that always tries to run ebay/second hand parts/knock off brand stuff when able.

Maybe I should send you some $$ and get you to ship some down here to Sydney...hehehe

i have a theory that the larger holes in the sard's make for poorer atomisation down low.... i.e. the fuel from the quad squirters is in smaller particles and can ignite easier.... hence the sards being worse on idle... and the tune having to be richer

e.g. bombtrack's car uses a LOT more fuel than mine (same mods) around town and idle, but on the GOR cruise return where we were on WOT all day we returned the same eonomy

hrm, they are back up around $1100... well, they were $1000 when i looked last :(

But prices change fairly often at the moment, not too stable... so $1200 delivered it is... fark...

Sorry, forgot to mention that was $800 USD. I'm a yank living in japan remember :(

My sards are fine, no rich idle issues and were supplied with plugs to suit - easy as. Only drama was they needed a couple of copper washers to space them off the rail as they seemed to be a few mm too short which resulted in them popping out of the manifold when it came on boost.

You could always bump the fuel rail pressure slightly... would help that :)

      Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
