just need some help with this, i have all the supporting mods and want to make around the 260rwkw.

almost at tune stage but need to know whether or not i need to buy bigger injectors or whether i can just put a fuel pressure reg on it and bump up the pressure.

i have an ignition DVD with a hybrid 25/30 in it making 280rwkw on standard injectors, how is this done, i thought they max out at around 220-230???

also if i do have to put injectors in it, will i also need to put a reg on it??

cheers in advance

injectors. when u put in a adj fpr, u are moving curves that aren't usually moved. making the whole tuning process a lot more difficult.

just go injectors and a decent management system.

dont cheap out on it.

hey SL1D1N, I in no way mean to hijack your thread, I am in a similar position (should have similar power by this weekend) then will need a tune and fuel system upgrade, and I was going to ask a similar question as you,thought it might just be able to be answered here instead of opening up a new thread....

So to upgrade the fuel system, you don't need to get a FPR if you get new injectors and pump? and does that mean a fpr just uses your current injectors to spray out more then what they are meant to? wot about your fuel filter when upgrading?

Thanks mate, Adam

BTW good luck with the tune!

Using a FPR to increase the pressure to get more head room out of your maxed out injectors is a short cut. If you are going to chase bigger numbers down the track you are going to eventually need bigger injector anyway so you may as well get them in the first place.

Yep, s15 sr20 480cc side feeds, or any of the 550cc ones are fine for up to 300rwkw(or 350 for the 550's) Upgrade the pump and keep the stock reg. What management are you guys running.

Awsum, thanks for that. I thought my mate was full of cr*p when he said I need fuel pump,injectors AND a fpr...

I have a powerfc and commander :)

      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!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      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.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      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.
