is it possible to use cobra injectors on my rb25?

[Iknowthefuture]

I have a set that were going to go on my ls1 t/a before I decided to turbo it. They are made by Bosch for Ford. Theyre Motorcraft. These are the newer EV6 style from Bosch. They are rated at 39lb @ 40psi. They are high impendence.

They are 47 Lb/hr @ 58psi.

Would a picture help?

by this post I mean after I get a greddy style manifold and aftermarket fuel rail.

An easy way to check and see how much HP your good for is use CCs = max hp. Then you want a little head room so you don't exceed 80-85% duty cycle. If you want 800hp, I'd get some 1000CC injectors.

The ones you have now would be good for 390HP or 470HP depending on the pressure, that's with no head room, so really less then that safely.

This is a rule of thumb for 6 cylinders, it doesn't quite work for 4 or 8 cylinder setups.

i guess you miss interpreted my question. would they physically fit and mate up to the fuel rail and manifold properly.

Seeing as this is a rather specific Nissan specific sub-forum, I am inclined to believe most people here are not familiar with the Ford / Bosch / GM injectors that you are referring to.

The quickest and simplest solution: try inserting said injector into said rail. or your stock rail.

Next time please try to be less vague.
"Will this specific injector (style / dimension) and specific rail function together properly?" , not 'Will $random-stud fit into $random-bore?".

I went against my natural instincts and decided to look up this 'EV6' injector. You are going to have to find / discover / bore your own top-feed style rail. And bushings / seals.

GReddy IM's (and their clones) use the stock side-feed injectors.

39 lb/hr is not much larger than the stock 370cc injectors at the same base pressure...some people run elevated rail pressures but it is best to run 'stock' rail pressure.
sure i could make my 720cc injectors into a set of 830's by running a 58psi base but then factor in that i also run 22psi max boost...thats 80psi of fuel pressure.
while it can be done, not the best idea imho...can lead to spray pattern issues and potential tuning weirdness.
you could run them at the 58psi base pressure (which is what alot of domestic cars do) and tune around it but eh...i'd rather just sell them and buy injectors rated at nissan's accepted base pressure.
