usually the 'wrx sound' comes from a cylinder not firing.

you can just test each cylinder by shutting them down one by one (i pulled spark plug leads on my old car). when you get to the misfiring cylinder there will be no difference in the engines behaviour, then you will have to try other avenues on this cylinder, -test for fuel / spark

however if yours is doing it whilst at certain rpm points, then you may need to have someone hold the car at the right rev's whilst you are doing this

      My apologies. I forgot we were talking about weird beard M series stuff. Had been talking elsewhere with someone about an R33 with similar subject and got confused.

      Nope, I don't like the look of ND RF, or any ND really, I don't like their faces or arses, why, because of their "modern" lines, the NC, whilst "modernish" has a more rounded shape that I like Well, that's how my overly judgemental eyes see it anyway

      Should be more than fine, especially the overall fuel pressure would never exceed 3.5bar (assuming that thing never gets more than 0.5bar of boost in stock form). According to the chart, it's 11amps.

      I definitely know the first rule here, look first, ask second. I've seen many people get roasted 😂 I found a few diagrams for the RB, but I'm yet to come across one for the VQ. From what I have read, the pump gets the +12v along with the FPCM, and it's the negative wire that gets passed through the resistor to regulate the voltage. So I assume I can just ground the negative wire at the pump to eliminate the FPCM control. But I really wanted to see the VQ circuit diagram first to make sure I understood it correctly. Once the new pump is in I'll do some testing to see how it behaves, and in the meantime, I'll keep looking for a wiring diagram. Thanks for your help mate, your time is greatly appreciated.

      Jacks that fit under GTR lips that can reach the subframe?

      Maybe? I have the Supercheap ToolPro low thingo. It has a somewhat smaller diameter lifting "bowl" than you would expect on a workshop grade trolley jack, and a split rubber pad to suit that diameter. It clears the "N1" style skirts I have. Probably wouldn't if the jack's bowl and a suitably larger rubber block were in use. Having said that though.....you only need the rubber block to exist on the inner side of the pinchweld, so could carve away any rubber that fouled the skirt, leaving some there for "insurance" </simples>
