You aren't from Vic - So unfortunately what you can do in your state has no bearing on this topic at all.

So as i said earlier, I'm very confident you'll never get a ~300kw LS1 registered into a R31 (factory of what, 140kw) in Vic which was the conversation being had.

Sorry forgot this was a Vis topic. WOW i though SA was the toughest with engineering! But they are actually about 245fwkw, S2 VY n VZ SS, not being a smart arse, and put out the same torque as my 25 got approved with.

How do you guys go about engineering? Do you have to under go seperate tests at a certain price per test? Chassis strength tests, lane changing tests, braking tests?

Oh it's an older one, not the 286kw one or whatever? (not 100% upto date with LS1 outputs in whatever forms)

You basically get scrutinised for everything from Emission controls, brake/drivetrain upgrades, engine mounting, frames, exhaust noise etc etc. IIRC as soon as its non-factory, non-family option - you go through the ringer.

I think more than a 20% or 25% power increase it gets tough and the other issue is the torque figures will be what will really hurt you.

EG. You can't engineer a LS1 into a torana or anything these days here. The VASS Engineer who did my car (26 into a HR) was telling me it happens often as people do the conversion BEFORE checking with a VASS signatory. They haven't signed off once since some changes were made a few years ago. Not sure what they were though, i didn't go into more detail on that topic at the time.

Cost/Effort wise it's a certainty you'll get a RB in, and cheaply simple due to the fact it's Nissan and it's bolt-in effectively with just a brake upgrade to the same or similar spec the motor came from.

Fken Victoria is seriously 15 years behind. The EPA laws are from 1992 :(

Ah ok. Yeah we are the same when it comes to all the tests. You have to have papers and reports on EVERYTHING when you go for your inspection. I have a whole folder in my car that i have to carry around with me at all times for the police haha.

Yeh my mate said it wouldnt be easy but its do-able.... But like you said $$$$$. In total over here, it will be about 4k for papers, compared to 2k for the RB, not to mention RB's being a hell of alot cheaper. The set up i have will be fine apparently, the only thing is the clutch bleeder location.....a hole in the passenger side tunnel with an extension to bleed LOL

      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!

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      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.

      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.
