stock fuel pressure for a 93 5sfe?

venom00 · 07-02-2009, 12:22 PM

Does anyone know the stock fuel pressure for a 93 5sfe? Or maybe a good psi to run it?

Most EFI Toyota 4 bangers are 36-42 psi running.

thnx cause i didnt want to put my fuel pressure regulator on and not have it at a good psi and mess it up

why are you changing the stock regulator?

The BGB calls for 38-44 psi

What wheels do you want to trade? Im looking for wheels and have a brand new turbo not used yet.

Have you tested the fuel pressure? 93s run 2+2 batch fire, so they should actually run leaner than the 91-92 counterparts.

The ECU will compensate for the new parts by modifying the fuel injection pulse based on the signals from the O2 sensor. If you have a slow O2 sensor (worse yet, dead), it'll take longer for the ECU to adjust the injector pulse width, if at all.

There's also other things that cause the ECU to enrichen the fuel mixture.
