But what i am posting a bout is what brand of extractors are used in the extractor install guide on r31 skyline club.

Your help would be appreciated

GTS1/2 are good, plus you can heat heatsheild them, Genie/Pacemaker are good. Really just go for any that are mandrel bent, and a more decent performance based brand. Some of the cheaper ones (aka wilcat) are really just for stock manifold repl;acement (when it cracks) and have pretty bad flow, I've deconstructed them before, they usually just have the pipes stuck in randomly with welds around them, look OK from outside (excluding press bends) but ont he inside, soo much turbulence and uneven cyl restrictions.

That said, its not really going to make too much difference on an unopened engine.

Extractors will change the note, make it a bit more raw and rough/throaghty, and generally give you a bit more mid range (if they are properly designed to scavenge) as well as give you more flow up top when matched by a full 2.5" exhaust with straight through mufflers/'highflow' 2.5" cat/decat.

The more generic extractors probably wont give that much of an improvement to mid range, and yeah like 2-3kW of top end performance loss (on an otherwise unrestrictave exhaust) but will still be better than stock manifold.

A GTS2 cam is a good idea, makes the RB30 a lot happier in higher revs (but can be a little doey down low without remap), I'd get an XF throttlebody and fit it to your intake manifold (remember to port match the plenum) then a Z32 AFM, 3" mandrel intake pipe (with a think a 60 degree bend is ideal) with enclosed pod filter, and finish it off with a Nistune chip (like $90 to get fitted to your ECU on exchange) To suit the Cam, AFM and 98RON fuel, and the old RB30 will be quite lively, usually >110rwkW at like 5500rpm on a healthy motor. Which is good power for a P plater and such a torquey engine, and is about 20-25rwkW more than they get bog stock.

I miss the good old days, with basic easy mods...

You could possibly get one s/h off R31skylineclub forums, otherwise you can get your current cam reground to GTS2 specs at somwhere liek surecams/crowcams etc.

You could also get it ground to different specs, maybe a bit better but i'm not sure if nistune can tune them off the shelf (i.e. not custom tuning on the dyno) if you sent matt @ nistune an email, he could probably tell you the specs of the cams he has already got maps to suit.

      FWIW a lot of the local owners that do a big build tend to have cars that are perpetually broken.

      R34 GTT Battery Relocation To Trunk

      By Watermouse · Posted

      I just got this system but haven’t installed yet I got a Moroso sealed box (defect reasons) which will be set up same as their pic The quality is high grade, the correspondence I had with the owner (former head designer for Rockford Fosgate) was unbelievable, guiding me with what I needed. Even told me not to buy some things as it could be sorted in a different way at his loss. Just a bit of a bite with the exchange rate and don’t purchase gear in 1 hit that goes over $1,000 au, lol I forgot!

      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 eliminate 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? (Apple car play? Android air play)? so If I swapped head units to save using a band expander, I’d likely lose those better features to have an oem Unit operational. Better to use a band expander and retain AirPlay options and newer version of head unit     provably best to band expand it, and focus on the nav unit. th isn’t  a big deal/ would be cool to have it working  from what I can tel we use a PAL Signal and Japan uses a NTSC signal  I don’t know if there’s a co better or if the screen only reads NTSC, or if it’s the tv module that needs replacing… no big deal don’t need it but more of a curiosity thing on that!   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

      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.
