440cc Injectors
440cc Injectors
question? i am going with the ATI supercharger standard system for the g35 coupe 6speed. i want to know if the factory injectors can handle the basic boost system it come with. this is my setup i am planing. i am using the inline pump and the digital fmu the system come with. plus a ecu flash from alteredatmosphere. i am not trying to go for big numbers because i heard the VQ engine cant handle big boost so i am just going to with the 7psi. any suggestion on this plus is it reliable for a everyday driving?
at 7psi, the stock injectors will be just fine. but, if you are planning to increase boost later, then you might as well upgrade to the larger injectors and get the labor part over with.
and one you go turbo, 7psi will be fun for a week, after that, you're going to be hungry and start buying more parts to increase the boost.
also, the FMU is okay at 7psi. but a better fuel management system would be a lot better because you can tune it to the exact spec you want. I believe you can use the Greddy management system or even the AEM EMS.
Too bad we don't have the "Hondata, or the free stuff such as uberdata and nepTune"...

Your definitely going to want more boost later, might as well get the labor done while you are installing the kit. 440's will also help lower you injector duty cycle which puts less strain on the fuel pump and overall fuel system. If you are interested, I have a brand new set of injectors for sale.
No point in getting bigger injectors unless you plan on building your engine, because you are not going to want to up the boost unless you do build your internals. Just stay stock injectors and stay at 7lbs. You will be relatively safe.
