Advice On Fuel System For R33 Gtr

[bonestorm007]

Just planning a fuel system for a R33 GTR.

Aiming for enough flow to support 2860-9s with 700cc injectors, a 98 tune, and another with E85. Ideally a set up that would be good for up to 330rwkw and maybe even 350rwkw in the future. I'd assume a bosche intank 040 wouldn't do the job?

Im leaning towards a surge tank for piece of mind at the track. Would the standard intank and a bosche external 044 with surge tank cut the mustard?

These pumps all ok with E85 fuel?

Cheers,

Luke.

You might want to replace your intank pump as well if it is the original unit just for peace of mind.

[bonestorm007]

Cool. So options for these power levels would be:

1. keep intank, and a Bosch 044 external.

2. Walbro 550hp intank pump, and a Bosch 044 external - recommended.

Cheers.

First option is better.

[bonestorm007]

Really?

Will that set up flow enough fuel with the increased fuel requirements of E85?

My current standard intank fuel pump seems in faultless working order, so if I can get away with leaving it and adding a external 044 that would be good.

Cheers.

if your running a surge tank you dont want a powerful efi pump in the tank, keep the stocker in there

[KiwiRS4T]

My reasoning is that more than a decade old pump can go from appearing to run "faultlessly" to failing overnight so I would prefer a brand new one.

[JonnoHR31]

but if its not the main pump it wont be dangerous, it'll either flow enough to feed the surge or it wont, in which case the car wont run. my intank pump has died twice (bad wiring) and the car simply drives until the surge tank empties and then dies

[bonestorm007]

Thats exactly what I wanted to know. As long as the external 044 with surge tank will

1. will flow enough fuel for my application, and

2. not be at risk of leaning out if the 10 year old intank does run into trouble one day.

Thanks Jonno.

Considered a Nismo intank (no surge tank)?

[R31Nismoid]

You dont need a surge tank, the stock GTR tank is fine.

380rwkw GTR's running semi's - no issues with nothing more than a replacement intank pump.

Go with a replacement intank pump. Simple, easy, less fuss.

[bonestorm007]

Would an intank bosche 040 with new wiring be a reasonable option?

Are the Japanese intank options better or easier to install than an 040?

[pistol-pete]

just get a nismo one, straight swap. simple is easier

Or.............do a search!

This topic has been covered SO many times before, pictures, prices, specs - everything covered.
