Sard Or Nismo Injectors

[DaveO74]

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

[DaveO74]

Ahhh, So would I right to assume that in theory the dual spray "may" produce a better A/F ratio but as you have stated you probably wouldnt notice it in a real world application?

its supposed to give a better mix of fuel and air before ignition. i spent the extra and went the nismo route as its a direct drop in and plugs into the factory loom.

[R31Nismoid]

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.

[DaveO74]

R31Nismoid-Mate can you tell me where you have seen the Nismos for around 1k? I cant seem to find any under $1200 but maybe im not looking in the right areas I shouldve grabbed some last year when they were were $870

Bloody economic meltdowns!!!!

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

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...

[DaveO74]

You just wanted to get my hopes up

[JonnoHR31]

put nismos in myne, easy to install and car ran perfectly on the same tune once i changed the settings in pfc. never had any experience with sard but as said, for the little extra go nismos if you can

[DaveO74]

Thanks guys you helped me make up my mind. Ill go with the Nismos

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

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

[DaveO74]

Ahh yes yes thats right my bad

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
