got the option of either Nismo 600cc or Sard 660cc for the right price

RB26DETT

N1 turbos power fc axhaust cooler etc etc

has made 274kw on 17psi maxing the injectors.

so putting 044 intank and either of the above injectors and retune next week.

car is street cruiser / circuit car.

are these injectors similar or does the nismo have better spray pattern twin pintle etc.

mainly concerned about fuel economy.

cheers

was in RWD.

on that note but you shouldnt believe that rwd KW is higher than AWD KW

my old GTR made 410KW in RWD and then straight after made 419KW in AWD, this was on a dyno dynamics dyno.

going back on the dyno next wednsday after putting in 044 intank and the tomei 600cc injectors,

was maxing the old injectors out with stock fuel pressure reg

yeah I'm pretty sure the nismo RB26 top feed 600s are single hole. nothing wrong with them though, or the sard 600s. I've used both and also the sard 700s and never had any problem with either of those 3 types. in fact I'm now using the sard 1000s and they are good too.

Nismo are 4 hole

Sard 700's are 2 hole

Sard 800 are 1 hole

That's if my memory is correct

are you sure you're not thinking of RB25 side feed injectors? this is like all the people who keep saying sard 700s don't fit RB256 fuel rails etc... they do.

Hrm i might well be. I keep getting bloody confused as I've had too many sets over the years.

Although i did sell Nismo 660's recently and fairly certain there was 4

I'll try see if i took pics of heads when i get home tonight. I took some pics, just can't remember what of exactly.

    • You very likely need to get it on a dyno and tune it. My assumption is, you've got an RB25DET tune in it, which has a different manifold, different injectors, and different cams as a minimum. What O2 sensor are you running?   When you say it runs extremely rich from idle all the way to redline, is this just free revving it you see that?
    • I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.  
    • I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.
    • Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.
    • Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...
