That would explain why a slightly moded jap spec will spank an aussie version with the same mods. however start changin the oz spec engine managment and u have the identical car!

Don't forget guys with the aus version S15 if you go for an aftermarket ecu,

Eg: Apexi Power FC you have to switch wire 30/31 on ecu wiring harness to run the fuel pump & i think the CAS.

:D

jap spec has bigger injectors, and a 6 bolt roller bearing turbo compared to the aussie 5 bolt. the steering wheels are nicer in the jap spec, the exhaust in both is very simiar and from my experience the difference in boost is minimal if at all different. ice performance have told me that the most they are able to speeze out of the aussie spec is about 180rwkw and jap spec more like 215rwkw. I have witnessed first hand two of my freinds going at it. one had a stock japspec the other an aussie spec with catback exhaust, and the japspec raped it everytime

Australia is also hotter and has shitter fuel, so the ADM version has less timing in it. Another reason why you see stock turbo JDM S15 crack ring lands when kids ram in 1 bar of boost with the stock ECU/tune and go to Mexico.

Jdm makes 184kw@fly. Adm makes 147kw@fly.

As noted above Jdm has more timing advance.

Jdm has digital climate control, adm is analogue.

The Jdm's imported where the pre Adm years so i think that was 99 and maybe early 2000.

I wouldn't worry about which one, just buy the best condition example you find. Personally i favour the Adm version as there is less chance of the odometer being wound back and less chance of rust due to climate conditions. They are things to definitely check for on either model.

Aussie versions of cars also end up with factory immobilizors where the Japanese ones won’t 

Then you install a JDM ECU, swap the 2x CAS pins and 1x fuel trigger and off you go - or BYO Haltech/Link/MoTec/ etc.

Poor effort on the NATS lol.

My stock NA 86 makes more @fw than the ADM S15.

I don't want to talk anymore about this though......

 

I like my 86, but I lay awake at night thinking of what could have been.......

Yep, except an s15 can make 200rwkw tuned and around 220rwkw on e85.

Sadly I missed a ultra low km one owner ADM when I was looking.

 

The thing was like new, stored, it had 5000km on it if I recall right, it sold for $28k I believe, which I would have paid.

It was red, a yellow one, exact same condition, owned by the same guy sold about 2 months prior.

I doubt I will ever see one in that condition again.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By Bireley_32 · Posted

      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...

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
