G'day guys. Just wondering if anyone can tell me what sized injectors i've got on my 95' R33. I've had the car for a few months and am still finding new things under the bonnet.

The injectors are Denso, part number 1995500-2240 and have a pink head on them. Any idea how many cc's are these??

I've also got a mate that wants to know what colour stock R33 injectors are (his are purple) and even a part number if possible?

Any help's appreciated.

Thanks

Thanks for the reply boli, i ended up finding that site just after i posted this.

I'm guessing the ND stands for Nippon Denso and they must be the same make as the sard ones.

The only thing is, i've got an RB25DET and they're stated for the SR20DET. I'm assuming my fuel rail takes the same injectors as the SR20DET?

Has anyone else heard of these Denso 550cc injectors or can confirm that they are 550cc? I've got my motor going in for a rebuild and was hoping i wouldn't have to upgrade when i put a bigger turbo on (GT2835 or GT3040).

Nismoid and Ben, i've still got the factory ECU but it's been reburnt so the fuel settings shouldn't be too bad. Can't usually run bigger injectors without some sort of remapping. Current is reduced so they don't pulse so hard. My car does run a little rich but not to the extent that oversized injectors on a stock ECU would be. The car was from Japan with a heap of mods. The motor's just s**t itself because there must have been a huge turbo on it before they sold it (was a smaller than stock turbo when i got it, R31 i think). Going in for the rebuild at the moment.

When upgrading my injectors I did a little research into the JDM/OZ spec S15 injector issue. Unley Nissan here in Adelaide (known to be 'import friendly' dealers) couldn't give me an answer as to whether the JDM & OZ S15 injectors were the same (I'm sure someone on SAU knows) APS in Melbourne would know as they highflow the stock OZ S15 injectors as part of their JR (?) kits. 6 new S15 injectors from Nissan Aust are more than 1k!

Boli,

As Steve said, excellent link mate!

Steg33,

If you look at the site Boli posted you can see in the 3rd & 4th columns in from the right it gives you cc rating at higher fuel pressures, i.e take the top injector (stock RB25DET/SR20DET) at 3.55kgcm2 of fuel pressure the 370cc injector will flow 440cc. This is how stock RB25DET injectors can support quite large gains in hp. Pushing injectors beyond their rated capacity (via a reg) is not wise unless the fuel pump is able to cope with the increase load placed on it.

EDIT: It's also interesting they list what appears to be the minimum duty cycle (milliseconds 0.69 etc...) achieveable depending on the fuel pressure used.

    • Hi all,   long time listener, first time caller   i was wondering if anyone can help me identify a transistor on the climate control unit board that decided to fry itself   I've circled it in the attached photo   any help would be appreciated
    • I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!
    • I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
    • The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.
    • No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
