Doesn't matter they will still put the engine number onto your rego papers by doing what I said

The current rta rule is you can increase the engine capacity by 20% without needing an engineers cert as long as the engine is from the same family as the original

If they put the rb30 engine number, will he then get defected for having an rb25det setup attached to it?

No because he requires the pollution gear from the r33 to be fitted to it, if he removes the pollution gear from the car then he can be defected for not having that but not for the bottom end being changed.

It's the same as fitting an ls3 into a car that had an ls1

and now to add to that, there is also a limit of 20% increase over factory power output too, see point 2 on page 3

however if someone was to have a dyno sheet with a run done at say 50% throttle you could say hey look this is proof that the motor makes less power than the standard rb25det

Pea shooter exhaust, cam gears retarded, 7psi (or a boost leak), tune with no timing

Lots of ways to reduce power for engineering.

I drilled a hole in bung I'd used to block blow off valve to create a boost leak and passed wa pits with a setup that made twice the standard power.

yeah but the block is older than the car



Emissions controls for the Rb are all related to the head.

Mine was engineered with a high mount gt35 and 3.5" exhaust (big mufflers, no cheats to make it quiet), but mine was done years ago and I also had to go get it emissions tested. E85 and a nice big 400 cell cat or two helps make that easier.

      Rv37 400r questions

      By sonicii · Posted

      No idea about the remote start part. If the V37 nav is anything like other Nissan JDM vehicles, you can't get the factory Japanese nav working in australia, a card from a different car almost certainly won't work, those cards are usually matched to the serial number of the DCU.  You could be possibly swap out the components from a AuDM Q50 to get it working, but if this is a new model (2021+) 400R, then you will lose the newer features like ACP/AA.  That said, if you have ACP/AA, just use google maps.. I assume a band expander would be required to get the local radio stations, but don't forget the Japanese FM band is narrower than ours, so you still might not be able to receive all Australian stations. I can't see any reason the tyre pressure sensors won't work here, there is the sensor unit inside the rim and the receiver nearby in the wheel well.  I have never had to change the batteries on my 2015 Q50, so I assume they last quite a while.  A straight battery change shouldn't need them to be re-registered as they are the same unit, that should only be required if you replace a sensor with a new one.   Word of warning, if you ever go into the 'secret' diagnostics mode on the main screen, DO NOT EVER do a 'reset' in this menu, it will erase all of your model specific data in the DCU and you will need a trip to a dealer to re-program it all, which would be particularly painful being an import.  This applies to the AuDM Q50 too.

      There is a known issue with the mix door motor on the Q50 which causes these symptoms, not sure if it is common on the Y51 though.

      Rv37 400r questions

      By elir32 · Posted

      Hey guys. I have a 400R on its way to Australia from Japan currently and have a few questions I’m hoping others may be able to help with.   Wondering if anyone here has had any luck getting the Sat nav unit to work in Australia!? Assuming the Stereo is as simple as a band expanded and tv won’t work?  Seeing as they’re based off a Q50 which is Aus delivered is there any way to link that system to the nav? Nav modules and head unit are different part numbers and appear slightly different at the rear with plug ins etc. can I put my xtrail sd card into the rv37 and will that convert the maps or update to Australian? Has anyone got any advice here?     also has anyone fitted the factory remote start and Security system once it’s landed in Australia? I put an enquirey to Nissan Japan in via a third party, and they suggested it needs a Nissan Japan dealers device to setup and couldn’t guarantee if one here could do it or not. They can supply and I can physically fit it but to setup I would need a dealers device. Any information here would be appreciated also. I’ve seen one here with it fitted already prior to leaving Japan at a dealer/inporter, so clearly passes compliance and works when fitted Japan and doesn’t need changing here.      also, does the tyre inflation sensors work here? Does anything change with them when the vehicle arrives? Where are they actually situated? I’ve read they have batteries and they need to changing at times and seems like resetting involves the nav system?    any help here would be appreciated and any other aust specific information to help would be great. Looking forward to see what the current generation skyline is like and eager to see how many of the gadgets can be utilised here.  Thanks in advance

      Do need to take it with a pinch of salt. One of the adapter failures, they clearly had setup issues with the flywheel.  One of the slipping ones I spoke to and it was pretty clear the throwout was riding, rather than fix, just swapped to a new clutch.    These clutches are being put in anything from 5k offroad 4x4 beaters, GR yaris, 500hp commodores to 1200hp barra monsters. Bound to be some issues in some of them when they are not a simple bolt in affair due to the changes in height.    There is a lot going on in this picture and unless I did the job myself no way to tell what really happened.
