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.

      Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL

      Jacks that fit under GTR lips that can reach the subframe?

      On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.

      Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
