Getting The Most Out Of A Built 26 And Gtss Turbos

[brembogtr]

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?

[SimonR32]

Yes it is worth it...

Expect a extra 30-40rwkw

[NYTSKY]

You will see mid to high 300kw range with those turbos on E85, about the limit of your injectors.

E85+2bar=

[R31Nismoid]

You'd say around 380rwkw if you had to put a number to it... What -5's would produce in PULP

[N1GTR]

You will max out duty cycle on e85 very quickly

[Trozzle]

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.

[joeyjoejoejuniorshabadoo]

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

[Beer Baron]

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).

[brembogtr]

380rwk would be the maxium out of these turbo's?

[GT33R]

One guy on here got 320rwkw with 555cc injectors on E85 so 360-380rwkw should be fine with 800cc injectors.

Or am I wrong because there is so many different opinions.

[R31Nismoid]

380rwk would be the maxium out of these turbo's?

On E85, educated guess... That is probably the figure give/take

[Blitz]

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

[GT33R]

I have HKS 690cc injectors, nismo pump and r32 N1 turbos. Would that support 310-320awkw on E85?

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

[Blitz]

Think of what i'd make with an HKS T62R?

Hardly relevant to this thread though is it

No one Um's and Ah's over the choice between GT-SS'S and a T62R LOL.

[Lithium]

Might be a slight difference in response of course

[SKYGTRONE]

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.

[Trozzle]

Coz going through a bit more fuel is a deciding factor after you've just spent thousands building an engine, right?

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.
