I'm looking forward to seeing this! Only 2 weeks now =P Still a bit intrigued that your NEO had the blanking bolt as opposed to a blank spot where a oil feed would go. I thought it was the non-NEO DE's that had the blanking bolt.

yeh it suprised me as well lol

mod list:

turbonetics stage 2 t3 turbo (450hp)

turbosmart ultragate 38mm

emu

gtt injectors

33 gtr pump

adj sard reg

adj exh cam gear

3" turboback

fmic

hoping for 200+

nice list, i have always liked their gt-k series with the black front housing.

but 1 thing im wondering... why choose a turbo that needs an external gate for now? if your aiming for 200-300rwkw, you could do that easily without an external gate...

how much psi u hoping to put in?

12psi atm.

i picked up this turbo for same price as a stock rb turbo and its a heap better turbo so i figure why not get it, has plenty of power left for future buildup if i choose to go down that path as well.

oh and ext gate sounds awesome!

well if it was that cheap then why not!

but wot about the manifold tho? with manifold, turbo and gate id imagine you could get a internally gated aftermarket turbo for the same price? or was this setup alot cheaper?

im only para because of the popo in melb... might not be as bad for u....

and yes.. external gates sound pretty bloody nice.

The biggest issue is if you use the stock ECU and a piggy-back, counter-tuning the stock timing is a little time consuming.

If you keep the compression high, the best thing to do is get a larger than stock sized turbo if you want to run pressure over 9psi, flowing the exhaust gasses out as quick as possible is better to stave of detonation. I've seen T04E's on these engines spool like stock from the higher energy combustion that you get from high-comp.

The fitment is pretty easy, can be done at home over a weekend with no real dramas.

When you say spool like stock..? I've never had the joy of driving a factory turbo..

So you wouldn't recommend running more than 7PSI for a factory R33 GTSt Turbo? I'm still running 7 PSI of the actuator, eventually planning to get a EBC, possibly a Gizzmo as they seem to be very reliable and excellent value for money. So perhaps it's best to have a larger turbo before running more than 7 to keep some sort of reliability?

haha yeah I just mean come on boost earlier, some turbos get a good 1000rpm earlier boost than if they were on a 9:1 engine, nice :laugh:

You can run more than 7psi, just you may need to lose some timing in order to do it...and it may be one of those things were the gain of boost ends up not netting much extra in power. A turbo with a bigger rear housing will make more use of the extra gas flow and as a result you can run more boost as the heat is getting out of the combustion chambers quicker.

the 33 GTST stock turbos are reliable at 10-12PSI afais. mainly on RB20s as there isnt as much stress on them as they dont spool up as quick as on the 25s. its when you go to 14 that you start having reliability issues.

Dan, are you saying having a larger dump/front pipe reduces detonation? (makes sense really when i think about it)

From the way I understand it, you want to get the gas out of the engine quickly. Too small a turbo and it will become a restriction to flow. Just like say an old factory cat converter in a high powered car, except that after the manifold, the turbo is the first place hot air ends up after it leaves the engine.

I would imagine that the front/dump pipe should be a size that allows the air to flow and scavenge optimally. Too big and you reduce the efficiency of the exhaust system. Would I be right in my thinking by saying that changing to a larger front/dump pipe but not touching the turbo would be like fitting a larger catback system, but not changing a restrictive cat? If a front and dump is able to flow enough for the given amount of power (lets say 3" for the average N/A+t), but the turbo isn't able to pass through the exhaust gasses quickly, then the restriction isn't the front/dump and changing to a larger front/dump isn't going to make much of a difference.

The goal would be to get the exhaust gasses out of the engine and out of the turbo quickly, therefore making power and more of it, efficiently, and lowering the time that hot air stays in the engine and turbo, therefore reducing chances of detonation.

Please correct me if I'm wrong

      How much roughly to convert stock r32gtr to single high mount turbo + ecu and tune

      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.
