iv just finished my build and want to get the most out of my setup so was wondering if i should get it tuned on e85 fuel

mods are

fully forged rb26

tomei poncams, cam gears, power fc d jetro, fuel pump, 800cc injectors on greedy rail, spitfire coilpacks, hks ignition and HKS GTSS turbo's

whats the most power that gtss turbos can produce? anyone have their 26 with gtss turbo's tuned on e85?

What fuel pump exactly?

More or less listen to the above guys, they know. I'd be using my limited knowledge to say around mid 300's before your injectors maxed.

Be sure the pump you have will suit your flow requirements though.

yup, as has been said or injectors will be the deciding factor.

make sure you remind your tuner to check the duty cycle and stop the tune at around 90% (wherever you guys are both comfortable)

i'm sure most tuners will do this anyway, but it is something that occasionally gets forgotten

yeah man, if you can get E85 easily enough where you are then I say go for it. there is sure to be some gain to be had in conjunction with more boost (25psi or so should be fine).

380rwkw is the highest figure I have heard reported from GT-SS's

I am considering testing their limits on E85 also and have sourced ID injectors to handle the fuel supply

Think of what you'de make on 2530's though :thumbsup:

Dont change to E85 you will probably regret, You will make the car "thirsty" it will drink alot. My idea is to change the turbos to GT-RS.

Its right you will get better performance and better "security" in the engine but as i said it will drink alot.

Clearly GT-SS's were chosen with response in mind - 330rwkw/PULP 380rwkw/E85

Now.. why on EARTH would be pick 450rwkw/PULP of turbo if he is chasing response, and on a 2.6l?

Silly suggestion, no extra 'security', just a whole lotta lag.

      R34 GTR Seats / No longer reclining

      By bilbo117 · Posted

      Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers

      Those above shitboxes, mediocre and above usually have a turbo strapped to them, hence the slightly higher octane is required.

      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.
