Re: Fuel system info

lets seee.....


your adding more AIR into the engine via the turbo. and what else does an engine need to run effectively and correctly?.... FUEL!!!!
if we add more air, without adding more fuel, the engine will run way too lean (aka hot) and blow up. that's not good. unless thats what you were going for. trust me it's fun, tearing apart motors!

so we need more fuel. hmmmmm..... how do we do that? bigger injectors and fuel pump. so even if your running 8psi on a SMALL turbo, your gonna want 450cc injectors which are good for around 280-310hp, and even tho you'll only be pushing about 260-270hp, it'll be good to have that margin of error.
and in order for the injectors to be pushing more fuel, your gonna need a bigger fuel pump, and the walbro 255 is what almost every single turbo honda owner uses.
