my friend upgraded his rsx turbo, he was boostin 9 psi. when he tries to boost 13 psi he cant the hondata ecu says it needs more fuel, injectors maxed out.
he has 650 RC injectors. no fuel rail no fuel regulator and no fuel pump.
he wants to get bigger injectors like 1000cc.
i said to him his injectors are good for 13 psi he just needs more pressure, i suggested a fuel pump only. the other 2 should be ok for 13 psi.
are 650cc good for 13psi? will he still be having the same problem with 1000cc?
need some answers

 

The reason he's running out of fuel is because he's running a stock fuel pump. You can throw 1000cc injectors in there, but you're going to have the same problem. If there isn't enough fuel getting to the injector, it still can't put enough into the engine. Get a Walbro 255lph HP and see if that makes a difference...it should. Those 650cc injectors are good for ~430whp

 

Not on the returnless RSX fuel system.

They run out of steam at around 340whp.

What turbo is being used for 9 & 13psi?

 

he is runnig a turbonetics t3/t4 full 3 inch exhaust, big intercooler.

i say he needs a fuel pump, but im not an RSX K20 expert..

 

He needs a fuel pump at a minimum.. If he wants to continue making power, he should look into a returnless fuel system..

 

Fixed for ya'.
