Fuel compensation with a turbo

How much boost can you run without having to upgrade your fuel system, or do you have to upgrade your fuel system period when turbocharging. I've seen many people run an upgrade such as a Walbro 255lt/hr fuel pump with an SR fuelrail/injector.
BTW this is for a Ka24DE(T) engine

An upgraded fuel pump is a necessity. Why risk blowing an engine for a $100 pump. 370cc injectors or bigger should be installed as well. 370's are maxxed at about 230-240hp.

4psi or so, dont go much higher than that 5 is def the limit, but its better to have a tunable fuel system, and at least put in walbro pump.

Bottom line...don't run boost without some kind of fuel upgrade. You will blow your engine if you ever hit over about 5 psi. Bare minimum is an FMU and a fuel pump, but that's just the bare minimum.
