car: 1993 r32gtr.

I am in the process of getting a pair of -7's to replace my stock turbos'

My engine is stock with no modifications apart from exhaust and ecu.

Does anyone know what a safe boost setting is before i start straining out the engine.

My intentions of changing the turbos was so the stock turbos dont suddenly fail and damage my engine

And by replacing the turbos I dont want to boost them that much that i end up blowing the motor.

Any suggestions/experiences greatly appreciated.

cheers

15yr old motor - unknown condition...

16psi which will give you around 280rwkw. Should hold and last nicely.

You can obviously run more, pust more etc but at the end of the day if you cant afford a rebuild then dont dance with the devil

280 is a good figure as you should be able to get away with stock injectors and MAFs. Many guys do the fuel pump as insurance since they're getting long in the tooth. You'll probably need a better clutch depending on what you have now.

Make sure you replace the dumps with something better and the o2 sensors while you're in there doing the turbos. Stock 32 dumps are crap, and in theory the o2 sensors are scheduled for replacement at 40,000kms. The originals may still be working but probably wont for much longer.

Try 280 first and see how you like it. You cant sensibly use that much on the street anyhow.

      I saw you mention this earlier and it raised a red flag, but I couldn't believe it was real. Yes, the vacuum signal should vary. It is the one and only load signal from the engine to the ECU, and it MUST vary. It is either not connected or is badly f**ked up in some way.

      @Haggerty you still haven't answered my question.  Many things you are saying do not make sense for someone who can tune, yet I would not expect someone who cannot tune to be playing with the things in the ECU that you are.  This process would be a lot quicker to figure out if we can remove user error from the equation.

      If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.

      I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.

      AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
