ive seen standard autos take 250kw with no problems.

ive also seen built ones take 300kw+ with a shift kit and a clutch rebuild.

someone on here has run 315odd kw on the auto, look up either 4doorsleeper or dangerman4.

both have high powered auto's and lots of info in their threads.

Yeah Keas in Melbourne is the right place but I would recommend you get a valve body upgrade from MV Automatics in Adelaide then get any old auto transmission place to put it in for you. Mike is head and shoulders above anyone else in Aus when it comes to Jatco trans.

Also I strongly recommend you get a trans fluid temp gauge in your car. It's well worth knowing what temp it's running at and would have saved me a full rebuild if I had one before I killed mine.

Yeah it's dangerman4, his last dyno run was ~300rwkw which, also is believed to be the limit of the stock trans w/ upgraded valve body. Also, a complete rebuilt one from MV Automatics has seen around 500rwhp.

so what have u done exactly to your auto tranny to get it to take 300kw?

With Just the MV Valve body it can hold up to 270rwkw, its a really good idea to get a Trans Cooler also to keep it from heating up too much. But shifts really nice well worth the money.

yeah i have a pwr trans cooler already put on. i like the sound of the mv shift kits but id rather get someone here in melbourne to do it in the shop. so the mv valve body is basically a stage 2 shift kit? is a mild or heavy when the gears change?

    • 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...
    • 310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
    • The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.
