Re: integra turbo question (boostinteg777)
just use an intank pump and fmu only works with stock injectors anyways, and its safe up to 10psi, but i've seen 14psi, but it puts alot of strain on the fuel system.

Aftermarket fuel pumps generally flow more fuel, but don't necessarily generate any higher pressure, and sometimes they won't make as much pressure as a stock fuel pump. When using an FMU, it's all about pressure, as the FMU will typically raise the pressure by 8-12 PSI per PSI of boost. So starting with around 40 PSI base fuel pressure, if you make 10 PSI of boost, then your pump will have to make as much as 160 PSI of fuel pressure, which many fuel pumps will not do. My fuel pump gave up before I got to 10 PSI, and I broke all my pistons as a result. I've heard of people running 8 PSI successfully, but that's pushing it. If you want to run more than 5-6 PSI, then get some real fuel management.
