Hey fellas,

Just thought i would check on here in case someone has had this with their cars,

RB20DET, in these cold mornings. starts up fine, idles at around 1000. drive for couple of minutes, the idle is up around 1500 cause she is still cold. been driving for 5 minutes now and the idle will go from the steady 1500 and drop to maybe 800, then back to 1500 and then drop again. the revs pick back up straight away, and sit back on 1500, just wondering what might be causing it?

My ECU is throwing 34 (knock sensor) could this be a possible cause? any other ideas, please let me know

Kind Regards,

Michael

i found out why its throwing that code, only one knock sensor is connected. the one closest to the fire wall does not have any wires going to it. as far as i can see, no wiring anywhere for it. so i will have to find out where to bring a wire from, or find out if i can just tap over from the other knock sensor

      Unsolicited advice? Keep the engine as close to stock as you can. Nothing wrong with adding some boost and making a little more power, but given where you are, you really don't want to try to make it into a monster. I can't imagine the roads are up to it, and the lack of locla support when it grenades will be a ball ache. FWIW, If there is a dyno around that you can access, then brand new injectors are a good idea, which will lead you to (at least) putting a Nistune in it, which will allow you to put an R35 AFM on it, all of which will make it possible to make it much much nicer to drive and live with.

      List all of your mods. It sounds like an aftermarket ECU hitting rev limiter. Like a valet mode, or a cold rpm limiter?

      "Cheap" bolt on turbo on RB25DET NEO

      By tylink720 · Posted

      @Kapr Haha yeah thats the one. I missed that you had a built up engine, I wouldn't want to run it on there either then. It was good in my situation just to replace the original turbo on a stock engine. @MBS206Yep definitely not a replacement for anything name brand
