  1. No damage.

    4door_Sleeper do you have a fuel pressure gauge, if you did i'm sure the needle would bounce around a little bit without you noticing.

    lwboosted What sort of fuel pump to you have, mine is a 500hp pump and it never made the noise until a few weeks of having the malpassi in then only makes it once in a blue moon since I installed the standard reg as well. I' almost certain is the arrangment of the rubber diaphram that causes some noise sometimes.

  2. i am planning on putting a rb25 in my 32 so if it blows that will give me an excuse to do it.. haha

    i will put the standard reg on as well and see how it goes.. but i thought that if i were to do that the pressure from the malpassi wold only hold it to the standard reg. and the standard reg would in a way block what the malpassi is doing because it becomes before the malpassi and the fuel rail.. if that makes sense...

    I know what you mean about blocking it but it will only restrict fuel flow back to the tank. Skyline fuel regs are after the fuel rail arn't they??, on the return to the tank, hence pressurising the rail.

  3. Mine used to make that noise too. They aren't designed to cop the intial wack from the fuel pump. The diaphrams inside flutter or vibrate with the pulsing of the pump. The fuel pressure gauge I installed at the same time used to bounce around crazy when it made that noise.

    The way to fix this is install your old fuel regulator after the fuel rail and then the malpassi then return to tank. (I assume they are the same as RB30ET's). Hook up the vaccum lines to both. The old reg takes the punch from the pump and they both regulate pressure up to a certain psi then the malpassi takes over increasing the fuel pressure at higher boost. Everything smoothed out so much after that and also allowed me to keep a lower base fuel pressure but still run higher than standard boosting pressure to maximise fuel ecconomy.

  4. I want to upgrade to a Skyline but that will require selling my VL turbo first. Just trying to kill two birds with one stone (don't like my chances).
