if i'm just gonna be running 5psi with my 5s-fe, is it necessary to install the 360cc toyota injectors? i don't want to run rich(or lean). one of my frineds friends flooded his spark plugs with oversized injectors. i don't want that to happen to me.

I would say yes. The 5sfe injectors max out at about 160hp if you plan for more you will need them....5psi ahould be about that.

Where did this 160 hp max out the injectors come from??????? I still got the stock injectors in my car and I have had no problems. I am currently running 7 psi max and with my 12:1 fmu i still run rich at max boost. The injectors are probably close to maxing out but I know i am running over 160 hp. I am planning to get bigger injectors very soon. But as everyone else said I would step up the injectors a size.... just to be safe at least!!!! That 160 hp idea must be off or i have some crazy stuff happening with my engine?????
Maybe someone can explain the 160 hp idea to me???? --------------------  |

The 5sfe injectors are 210cc/min and the 7mge ones are 330cc/min. Can someone do the math for the HP max I dont know how it works. From almost everything I have ever read you max out the 5s ones at 160hp. That is why most people with heavly modded 5sfe's sometimes complain that it feels like the engine has topped out. They maxed out the injectors. Im not sure if the 160 is crank or not but thats just what I have been told. -Bryan- -------------------- Member of Team 5sfTe
