7m-gte Fuel upgrade, 1jz Fuel pressure.

[92TealSupra]

I have my '92 Supra which I am almost ready to drop in the 1jz, now my question is I know the 7m's Fuel pressure can I use a fuel pump from a supra with a 7m-gte for this 1jz? Is the Fuel pressure different? Injectors are 380? 440, in the 1jz? Also can I run a 70 Psi fuel pump and use that stock FPR on the 1jz? Thanks.

don't solely go off of what i say but im pretty sure the 1j injectors are 440's as you were stating/questning. Also the stock fuel pump i belive is good depends. What are your goals you might wanna upgrade to a walbro while you have everything out and torn apart. and idk if it is also with the 1j but i belive the fuel injector resitors are slightly different.(dont quote me 100% on that). I know their is a way to get rid of the inejcotr resistor pack if you plant o clean up the bay and go all out build

The 1jz does not use ( Resistors ) the 2jz with 550's does though. If I did a upgrade I was going to get the Aeromotive Tsunami fuel pump, I just need to know if the reg would be okay, or if I need a aftermarket one.

1jz injectors ( yellow ones ) stock are rated at 380. You can use a stock 7mgte fuel pump to run and drive the car, but if you will be doing agressive driving and high boosting, you should upgrade to a walbro for safety. Your stock fuel pressure will work fine as well for stock engine. I did it before and worked fine for a daily driving stock engine but I changed it the first chance I got.
