Hi all,

I am a little concerned with the idle as I just got my r34 2 weeks ago and she idles at 1000 rpm [when warmed up]. The compliance sticker says it should be 650rpm and so does the japanese [OEM] sticker in the engine bay. Supposed to be 650 @ 15 degrees BTDC.

Just wondering what other r34 [turbo] owners cars are idling at?

I can adjust it of course but it seems a bit low and sounds a bit low too [@ 650]? :confused:

Thanks!

Mine's not a 34, but my 33 has always idled high (anywhere from 950-1050...

There is an idle control valve behind the intake plenum... There should be a screw which you can tighten or loosen depending on where you want your idle.

Personally I like having a higher idle - easier to get it off the line :(

Thanks guys!

I have lowered it a bit, its around 850 - 900 atm. On a cold start though it goes up to nearly 1800 rpm! Until it warms up a bit...I know idle normally is higher on a cold start but this is pretty high I think, and also loud with a/m exhaust.

1800.. thats high,

My R33 RB25DET does idle at 0650rpm when warm, which is stock, but i will probably raise it as it's easy to stall unless u give it some. When starting cold i think it stays at around the 1k rpm mark.

    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
