Fuel rail questions

[eggcatcher]

Hi, I'm after some more parts for my Hyundai Coupe, so after more info on the Evo4/5/6 engine.
On a stock engine, what is the injector size, and what is the fuel pressure regulator setting?

 

[EVOIV MJC]

Standard e4 engine has 510 and the rest 5/6 have 560 injectors,, Not sure about the other question sorry pal

The car parts are fitted, got a custom intake manifold with 2 TBs on it, however as its now running to lean I just need to uprate the fuel system to allow more fuel, and as my engines a sibling to the Evo 4/5/6 engine, thought about putting an evo fuel system in, as its capable of running an evo with the correct AFR it should be ok for me. Once those parts are fitted I can get a piggyback and get it mapped, and hopefully from there it'll be done. In the meantime until its mapped I've just unhooked the link cable between the TBs so it can runsafely on 1TB.

I presume that you have uprated the Fuel Pump?

I'm assuming the Evo pump is more powerful than mine, if not I know the Eclipse pump definately is.
