Hi guys I am planning to make my Auto S2 Stagea mody to power between 230rwkw to 250rwkw, and I know what parts to get and I already start doing this now but until some of my friends who own WRX and 180sx they said my car will need to change the drive line or gearbox thing otherwise my car won't make pass 165rwkw. They said my 4wd system is same as wxr not strong , is this trust?? If I want to mody my S2 to 230rwkw then I will have to change the all the drive line , like gearbox or diff??

4WD will be fine, it's basically the same as the GTR 4WD system which can handle alot more than 250awkw. The auto box will handle it, I'm running around that power with a stock auto, my only issue is flaring in gearchanges under full load. I'm in the process of getting a shift kit to sort that out.

no, the AWD system is actually based on the GT4 which was NA - the only GTR based systems were in the Autech. Its kinda interesting really, the stagea was the ONLY RB25DET powered AWD system Nissan ever made...

Yes the gearbox will handle it, as will the diffs, transfer case etc, but to make sure I would recommend a thermo controlled trans oil cooler and a shift kit as a sensible precaution

While looking for a shift kit for my re5, I was told the re4 was good for over 1000 hp once built.

+1 A shift kit will help stop the wearing clutch slip that occurs when powering up the engine.

Yes, and the re4 is a much stronger box. M35 uses the electronic throttle to limit the torque so they could lighten the box a bit.

So mine S2 stagea autobox can hold 1000hp? then should be enought to handle 250rwkw as well.

You will definately need a higher rated torque converter at that power. Mine sucked ass with the stock converter...

When mine was stock, my 60ft was 1.9. With the 30R+other mods and stock converter, it was 2.2.

Haven't run it yet with the higher stall, but feels ALOT better with it!

Only once built. I guess any more than around 200kw you would need the shift kit fitted at a minimum.

      Rv37 400r questions

      By elir32 · Posted

      Thanks mate for that reply. Very helpful.    it’s a 2022 400R so would most likely lose those features as you say.     I did a quick compare of a rv37 nav and heading for sale in Japan to q50 model. I’ll pop pics below. Seems  Japan spec head into top, nav unit second below it   below pic Q50 aud delivered     differences seem to be Aus delivered has a different plug top left hand side of head unit- not sure what and where it goes.   and nav unit Japanese tv37 had an extra plug put    Again I’m really not sure what each of these differences mean!       the actual plugs on a v37 and q50 screens look identical on both screens… pics below for comparing. (One screen was is a us delivered one) but should be same gps signals etc as Australia.    If it were as simple as swapping a nav unit from q50 aud delivered im interested -just want to figure out what the missing plug is for before spending big $ on a second hand part for it to not work, and I guess with the head unit, if the band expander does the job (I got a 20mHz so should get the range I’m after) so should narrow my issue down to nav unit only.  I’d love to know what the extra cable on rv37 does and if I elongate that part what it’ll do to the setup,    and also, if I can figure out what that head unit plug difference is, what does that cable do and where does it got can it be altered or re-plugged?! Excuse my ignorance what is ACP/AA, what does that stand for?   Thanks for the info re tyre sensors, helpful and great to know.  I was reading the online manual off Japan website and it seemed to make it sound more confusing than it is  I guess a rim replacement would require the sensors to be moved to a new rim to carry that option over?!     Thanks for the info regarding diagnostic mode. I appreciate your help mate. Trying to brainstorm here to find a solution to get as much gadgets as I can working! I plan to get my local Nissan tech to have a look too who used to be at an Infiniti dealer back in the day to see if any thing they have or idea can find a soliton. But hoping anyone here has gone down the same route to make life easier!!   i guess identifying the cable/plug differences and what they do would be a great way of finding out if the units are transferable    thanks again

      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
