I have USDM 2jz 550’s in mine. They are 1.6ohm so low impedance. Cannot be run by stock ecu. Apparently they have used these injectors in upgraded fuel system (rail, lines, pressure, pump) and made 600rwhp on a US dyno. Less on oz dyno but still shitloads.
However, I would probably buy a top feed rail and run some rochesters.
I am going to up the fuel pressure a bit as I have reached 96% duty but I am running pretty rich 10.5:1 up top.
Also SICO1j only uses 440’s with 60psi base fuel pressure to make 540rwhp but I can’t understand how. It is getting pretty lean though, close to 13.7:1 or even 14:1 up top so I wouldn’t recommend it for long term. However 550’s and upped fuel pressure seems like a good idea to me.
