Fuel Requirements - Rb26

[harks]

Hey guys

I'm soon to get installed the following mods

gtss turbos,

tomei dumps,

Hks front pipe,

kakimoto 3.5" exhaust and

either 3.5" straight pipe or 100cell cat

I have a viper ecu, elec boost controller and handling mods

I'm hoping fir 320-330 awkw on this, fir fuel set up I'm getting sard 700cc and planning on a Walbro 255l pump

Is this all I'll need fuel wise to support my power goal or do I need to get a fuel pressure regulator and fuel rail too??

Any other thoughts on what I'll need to hit my goal?

[r32-25t]

No what you've said is fine

[Hadouken]

You will get the power.

When you run e85 you will find your injectors will be too small.

But 98 is fine

For a few bucks more you may as well get the Walbro 465L pump which is ethanol friendly in case you want more than 500hp and decide to get E85 some time. Directly wire it and you won't need to revisit your fuel pump for a long time.

I was contemplating a 460 unit, I just thought it would be excessive. I'm thinking about e85 next year but thought the 460 would sound like a lawn mower starting up.

For $185 they are hard to beat, and the new turbine design is nearly silent.

[harks]

I guess that settles it.. 460l it'll be.

Can't wait to get my current turbos off now.. 21yr old vspec journal bearing, steel wheel old tech turbos are lazy as fk.

[Hadouken]

Bro. Pretty sure they are doing a he'll of a job while still pumping power through the motor that is just as old but probably will hold 300kw longer than the life expectancy of a ford

[harks]

touche,

they are still going hard.

My XR6 Turbo had 325rwkw and 400,000 kms on the clock...

[methz]

I would have to agree with scotty, im also running the walbro 460lph e85 pump and they are as silent as a stock pump

[Blackkers]

Whatever you do don't install a bosch 040

over priced, short life expectancy on e85 and noisey as fark

[GTR_JOEY]

Yep^

My nismo is louder then both my walbro 400s put together

[Piggaz]

True that. Your feed pumps are practically silent!

[harks]

Well having just lodged my tax return im getting a lazy few thousand back... soooooo im thinking about getting poncams while i get everything else done.. given ive got the turbos fuel and exhaust im thinking it should be worth it..

now i've heard mixed thoughts about whether to go R, A or B, im thinking i might aswell go B cause the GT SS will be responsive as hell, i dont mind an angry lumpy idle and also if im going E85 down the track will help the top end figure?

thoughts?1

[harks]

i should add there will be occasional track work, and if the engine lets go i'll possibly go -5's when rebuilding

[GTR_JOEY]

Type bs won't really make it lumpy, for that kind of power keep the cams you have and spend the money else where

Possibly on a decent oil cooler if you plan on tracking it or a brake upgrade

[Borci88]

Don't bother with cams, you won't make enough power to have any real gains.

[Piggaz]

If you're gonna go cams. Stock, type R or mines shore pro 2. Tomei type b's, too much duration for lift given.

Pm XKALABA. He has done a back to back between the 260 and 250 poncam. Sometimes, bigger isn't better.
