So my MPH is all good but im struggling with wheel spin so my 60ft is lazy.

Im on the left hand of the lane on this slip.

The right hand lane had drag radials on but I dont want to go there.  What is a good street tyre could be a semi slick but I want to be able to run on the street/summer driving.

R32 GTR with Stock 16" wheels and hunting the 10 sec pass.

Thanks.

How many passes have you done?

Don't be surprised if seat time alone does the trick.

It looks not only the 60 is a bit off so is the 1/8.

Which points more to seat time, tyres won't help there.

This, R/T is a bit sluggish as well

On this clutch and gear box 3....on the old setup that was abit shot to pieces 20 odd.

Achilles 123S are a pretty decent street tyre, a GTSt I tune almost hit 11s with "only" 123mph trap speed and very gentle launches because he was having axle tramp issues - doesn't sound that great, but ~12.1 in a RWD Skyline on 18" street tyres isn't too shabby even before you consider it still had some traction in reserve if it weren't for the tramp.

On nankang ns2000 tyres, the really naaaaaaaaasty ones with my hillclimb alignment in the car still i went 1.6 to the 60, 7.4 to the 1/8th and 139.9 to the 1/[email protected]. You have a 10 in that. Get the alignment sorted, drop your tyre pressure to 26 and try again

      Find out what RPM it was idling at with the IACV unplugged. It's very weird that the rpm didn't change at all, and then it stalled. When it stalls is it nearly like a switch off, like you've turned the engine off? Or is it more stutters and sputters and coughs to death over a few seconds? Or does the RPM just slowly keep going down and down? Have you done a test of trying to start it with the AFM unplugged? Does it still die?     If you Follow Josh's advice on using Nistune to check the voltages (which is a perfect method!) if you see anything out of wack voltage wise, THEN get the multimeter out and read the voltage directly at the sensor. If the two vary, then you're now looking for a wiring issue vs a sensor issue. So be aware, what the ECU sees, may not be what the sensor is actually saying too...

      You very likely need to get it on a dyno and tune it. My assumption is, you've got an RB25DET tune in it, which has a different manifold, different injectors, and different cams as a minimum. What O2 sensor are you running?   When you say it runs extremely rich from idle all the way to redline, is this just free revving it you see that?

      I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.
