Fuel System

[Johnny_B]

hey guys,

i searched but couldnt find the answers i was looking for

im just about to order the components for the fuel system in my s13,

im going to run a surge tank,

bosch 044

std intake pump as the lift pump

i will be using screw on ProFlow/SpeedFlow screw on fittings onto the surge tank with braided line hose clamped onto the std steel feed, return etc lines.

now i i am unsure what size fuel line i want to run? -6an or -8an?

im looking at making a reliable 400hp/300kw with an rb25det with rb26itb + other supporting mods

i am also not sure what to do in the way of injectors?

get jap-brand sard, power enterprise etc 800-1000cc injectors in a gtr type rail

or go with an aussie style rochester 1000cc and www.injectorsonline.com rail kit?

any help would be greatly appreciated

cheers John

its in there mate, sorry i probley didnt make it clear enough. An RB25DET with bolt on mods and RB26ITB

Ah shit sorry - missed that

Any injectors will do really, you only need 550-555's or whatever that Nismo offer up

You certainly do not need 1000's for your power aim at all.

no worries mate.

okay. would 2nd hand ones through yahoo japan or even the classifieds on here be my best bet, then get them cleaned flow tested?

any input on what size line to order though? will i be able to clamp -8an onto the standard metal fuel lines?

Just use 5/16" or what ever the factory size is, -6 is a little loose from memory, -5 would be good but hard to get and very exxy!

[Johnny_B]

Is there some kind of fitting I could buy to allow me to adapt -6 or-8 hose onto the standard steel line?

You could have a steel -6/8 male fitting welded onto your stock rail.

If your going to all the effort of running a braided line, it might as well be a -8 (1/2").

Or just run the 044 into the stock steel line.

imho, go 740cc injectors as if you wanna run e85 in the future you will want the headroom

my 555's hit 92% @ 325rwkw on e85
