Rb20 Fuel Rail On Rb25

[humz]

would the standard rb20 fuel rail fit directly on the rb25 and then directly take top feed injectors without any dramas??

any help would be appreciated

[CEF11E]

it won't fit in a million years

I have tried it. the rail is nearly twice as high than the side feed rail with the injectors fitted and it will not fit under the plenum. also none of the bolt holes line up.

i even looked at modifying it but there is just no way.

Yeah won't fit.

MR Turbo Australia sell the Billet Turbochargers top feed fuel rail kits for RB25's.

There number is: 07 5596 1079

[humz]

will it make any differance if im using a front entry plenum from sub zero, theres plenty of room in there fro clearance when compared to the stock one

how much for the billet kit?

[humz]

can anyone answer my 2nd question

[robots]

Want to know it also. Can use gtr 444cc on rb20 rail with greedy intake mani on rb25 ?

[humz]

i guess the impedance would be differant so resistor pack needed there.

not sure about the rest

RB20 fuel rail WILL fit onto RB25DET. All that needs doing is to machine up 6x adaptor rings for the injector base seals, and to weld new mounts onto the fuel rail.

And it WILL fit under a standard side-facing plenum chamber quite nicely.

Then GTR injectors etc can be used on RB25DET. A resistor pack from a GTR will be needed, or just wire in individual resistors. (Cost me $1.40 for each resistor).

Nigel., you are the man ! Thanks!
