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.

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 :thumbsup: 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

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 :)

      Actually,  just remembered there should be info in the threads (somewhere) about swapping to a manual steering rack and deleting power steering all together.

      Thinking of getting a Q50 300hp and just tuning it instead of getting the Q50 Red or 400R

      By 180 wanabe · Posted

      Also had a look at the Nissan JP website looks like the 400r has a slightly shorter ratio than than the regular V37 3.133 VS 2.937 which from a guy who has driven both 3.69 vs 4.11 ratios in the S15 is bugger all. Seems that the AUTO Z runs the same ratio as the 400R but can't find any info as to if its an open or LSD? More often than not the auto LSD is open

      R34 power steering

      By joshuaho96 · Posted

      Do not replace the power steering lines with this stuff. If it's anything like the Chase Bays stuff it will leak and be worse than stock. The reason why the reservoir is on the LH/passenger side of the car is because that's just where the reservoir was most convenient to fit. Don't overthink this stuff. The intake/cold side of the engine is pretty busy on these cars. And again, the hardpipe is designed to be a janky power steering cooler. In theory you can replace it with a real power steering cooler but that's really only for track use where boiling the fluid is a distinct possibility. Start with the low pressure lines feeding the pump from the reservoir. Make sure there isn't a bunch of junk in the reservoir filter. Be careful to not get ATF all over the engine bay. I hate dealing with ATF spills, you can clean it up and the slightest crevice will still release more oil that can still drip over time. You also want to inspect for leaks before you make a mess and can't tell what happened. Most likely you have a leak somewhere that is allowing fluid out and air in. Failing that it's allowing air in but not fluid out. Only place I can really see that happening is on the low pressure side because the pump will pull a slight vacuum to draw fluid in. Everything after the pump is high pressure or lower pressure, approaching atmospheric by the time it returns to the reservoir.

      Skid pans in/around Sydney?

      By Kinks · Posted

      I did a skidpan night at SMSP this week, it was much cheaper than $350. But yeah, you need to slap an LSD in that thing.  I put an OS Giken in the 370Z and it's f**king MARVELOUS even compared to Nissan's viscous LSD. So you're saying it's free now that it's a housing estate? 😂

      Nah, the car seems to run exactly as it did prior, in saying this it does "seem" to be better down low, like more eager to rev, but that may be 100% placebo effect from intake noise But, I'm not worried about it at all, in the end it is a fairly low compression NA engine that has a well shrouded intake,  if it is getting hotter IAT I cannot notice anything negative performance wise from the seat of my pants thrashing it about on the street or sitting in traffic, so meh, car now now makes induction noise so I'm happy
