does anyone know if i could just throw on these set of jdm 2jz 440s in my 1jz w/out any safc or some sort of piggyback? or will it run too rich to the point where i can't drive it around?

yeah it may run... but there is no point in doing it without a controller or 2jz map sensor to compensate. it will run really rich all the time and will not affect boost cut at all. all you will do is go slower and idle like crap. the 2jz sensor is a very easy way to compensate, the voltage output is different by the same ammount as the difference in the injectors. this will give you the right amount of fuel and raise bost cut.
