Hey all

a mate has a r32 gtst and the old rb20 has given up the ghost.

its a registered turbo rb20.

I have a spare rb25 in the shed.

my question is, how do you go legally registering a 25 in a 32?

To get it on the papers would u have to go through regency?

Or is it an acceptable engine swap?

Cheers

Variety of answers. For mine it was regency and make sure have adequate brakes on the front that suit the weight addition - i.e. R33 front calipers etc., or 4-pot type-M R32 gtst brakes. That was from my experience. Though, you wouldn't want to keep the RB20 gearbox with an RB25DET under the hood...went through 2 gearboxes with the RB20, so chucked the 25-box in with the RB25.

I looked into this when I had my 32. The best advice I got was to buy a front cut from an R34. Chuck in the brakes, motor, gearbox and wiring and go from there. Costs a bit but those motors are brilliant and if you put that motor in on the original gearbox you will blow them as mentioned

Coil overs are fine as long as the ride height is legal. That mod is fairly easy to make legal as long as the brakes are done. Making the wiring work is a different story however haha

Are you sure about that?

It's my understanding in sa they have to be engineered and have a mechanical way of limiting how low they can be set.

It'll be different in every state. Australia is fun like that. But yes it has to be engineered but apparently there isn't much of a drama in doing so at a legal height. This is according to an engineer I spoke to around 2 years ago. Things may have changed since then and be different in different states

Basically submit the form, you'll get a list of requirements needed.

Fulfil those requirements, do the tests, pay money and get a form saying its all legal...

Wont necessarily mean you wont get defected for it, just means you can roll through regency without issue (whilst paying them to inspect you're paperwork saying it's legal).

      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

      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.
