What size injector and fuel pump?

irelandbubaru · 11-12-2006, 06:52 PM

I am looking at pushing approx. 400 to the wheels in the near future using a fpgreen turbo, what size injectors and fuel pump would be a good idea to run to support that kind of power and at the same time have room to go more on the hp if I want to? Also would it be wise to get a fuel rail?

My car is a 2002 wrx.

The ej205 will be right at the edge at 400whp, and it will be a short life

So are you saying that the stock fuel system could handle it? MY02 has about 33500 right know and I figured that at about 60000 miles the engine would bite the dust? What size injectors and size fuel pump would you recommend on running for this setup? Keep in mind that I am going to fun switchable boost maps so that I don't have to run the high boost require for 400 whp? thanx for the imput.

Your going to have a hard time hitting the 400whp mark with a Green unless your using C16 and a friendly dyno. A 255lpm walbro and modded stockers should be sufficent for that setup. Good luck.
