hey i got a r31 with a rb26 motor and a rb25 gearbox. After driving today in the heat for more then an hour and only really giving it a hit twice i got home parked the car and came back out and the gearbox was pissing out liquid, is my box gone? Could it be something smaller? Liquid was seeping from the front of the box

The only thing i noticed when driving in hot weather is that when accelerating between gear changes the car sounds like a vacuum cleaner.

i had my clutch replaced when i bought my car and at the same time they replaced the rear main seal aswell.

about 2 months later i was in a hurry and WOT'd the car for a while (on a hot day). when i got back home everything was fine, car ran ok. next day got home from work and noticed oil where my car was sitting. turned out the rear main engine seal was put in backwards and produced a leak under sustained WOT. took the car back, they fixed it and never had a problem since. that was 3 years ago

    • Did and sync timing with light 
    • Have you done the Ignition Sync Wizard in the AEM software?
    • Find out what RPM it was idling at with the IACV unplugged. It's very weird that the rpm didn't change at all, and then it stalled. When it stalls is it nearly like a switch off, like you've turned the engine off? Or is it more stutters and sputters and coughs to death over a few seconds? Or does the RPM just slowly keep going down and down? Have you done a test of trying to start it with the AFM unplugged? Does it still die?     If you Follow Josh's advice on using Nistune to check the voltages (which is a perfect method!) if you see anything out of wack voltage wise, THEN get the multimeter out and read the voltage directly at the sensor. If the two vary, then you're now looking for a wiring issue vs a sensor issue. So be aware, what the ECU sees, may not be what the sensor is actually saying too...
    • You very likely need to get it on a dyno and tune it. My assumption is, you've got an RB25DET tune in it, which has a different manifold, different injectors, and different cams as a minimum. What O2 sensor are you running?   When you say it runs extremely rich from idle all the way to redline, is this just free revving it you see that?
    • I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.
