rs2 injectors

[denniselbows]

could anyone tell me if rs2 injectors fit the 3b or point me to any links

[Jamo]

Yeah they fit but you need to change the fuel pressure regulator to one from a 7A so that it runs at 4bar and not 3 bar which os the standard of the 3B

[denniselbows]

is there much benifit from doing so . do they give greater flow or better spray pattern

[s2_bo]

iirc you need a remap if you run RS2 injectors on a 3B or ABY engine.
Otherwise it will be running very rich.

But yes they do have a much higher flow rate, im sure someone can supply the figures.

You need a remap and the hole spray pattern of the ABY / RS2 injectors is far superior to that of the 3B injectors.

[denniselbows]

had thought a remap would be needed but that is a long way away yet. just trying to acumilate some parts for a future engine build . i saw pisobiker has some on his list of part he has put up . but i expect some one has already beat me to them already.

Yes of course they fit, but you will definately need a remap, and the 7A FPR is not necessarily needed, BTDT. Depends on what sort of power you are after.
