60k is coming up and i have some connections at a local suby dealership. I'm thinking in the future i want to go bigger turbo. When the guy is doing my plugs for the 60k i was thinking about having him throw in bigger "pink" injectors and a fuel pump.

basically im hoping that my accessecu will continue to power the upgraded injectors and pump like if they were stock untill i get the bigger turbo and different map.

is this possible? i'm assuming the fuel flow comes from what the ecu tells them to flow untill they run to max psi. i'm hoping for the ecu to flow the upgraded injectors and fuel the same way, even though the headroom will greatly increase with their larger size and flow capabilies.

bump for you insomniacs out there

You'd need to get street tuner or get protuned to make this work. The problem is the way the injectors work. They have a certain sized orifice that lets out a certain amount of fuel in a given amount of time at a given pressure. So say you have 420cc injectors, that means that in a minute they will flow 420cc's of fuel. If you have 550's in a minute of being open at the same psi they flow 550cc's of fuel. What the ecu does is tell the injector how long to stay open for a given combustion event. This is a set time. SO if the computer tells the injector to stay open for 10ms it will flow as much fuel as it can in the 10ms window. 420's will lfow less in that amount of time than 550's will. THis will make the car richer than it needs to be. So you need some programming to tell the injector to stay open a shorter amount of time due to the flow rate of the injectors. Given that you might be able to get away with 550's if you switched to an adjustable fuel pressure regulator and lowered the base pressure of the injectors. But that's not the best way to go about it and can be pretty tricky to accomplish.

thx drac9...i guess no injectors till turbo.
