I got a rb25de neo in my r32 and a couple of people told me my vct might not be working simply based on the fact that plug is not connected. I dont have a wire running to the plug. Does anyone know if there is any sure way to know if the VCT is working on not? The car picks up bad revs after 4000 but i heard vct is always working and not like vtec

thank you.

If there is no plug connected to your VCT then it is NOT working.

If you had the plug connected up to the VCT and it WAS rooted you will hear a Tick Tock as soon as you lift it above idle basically....mine is rooted and does just that when i plug it back in.

Are you getting some bad knock from your engine when you punch it?

How VCT works..

at idle it's off, when throttle is pressed and RPM between 1100 & 4500rpm it's on.. when it goes past 4500rpm it turns off again

so if it's unplugged it's doing jack shit.. it's constantly off :)

      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>
