Hey im bored and got money so i have decided to sell my 32 n1's turbos for a nre b/b set of either 34 n1's or something else prob is what is something else im looking for something that will bolt on the factory ppostion but if i dont go for the 34 n1's something that will make more power, not to worried about lag so i was considering maybe 2540,s with a set of cams would this be wise...

and question how much are 32 n1's worth these days..

A/r 60 steel wheels

I'm doing something different......mainly due to a few people getting pinged for import duty on Turbos thru Nengun and the like atm.

Anywho I'm getting my standard turbos rebuilt using Steel T28 Wheels, and having the Housing Machined, costs just over $1000ea to perform....should see 600fwHP which is probably 100hp more than i'll ever use :)

Did the same thing to my old 'VLT T3' was good for almost 400rwHP, and is still going strong after 2+years.

I will post results when complete

I got my GTSS through nengun! and a whole stack of parts... no duty or GST!

I wouldn't go running around advertising that fact. Regardless, you have to at least budget for the possibility when buying from Japan (US is a different story post free trade agreement).

I wouldn't choose the GT-SS's if your after more power than the N1s. I would choose at least the 2530s. 2540s = a mismatched turbo, so avoid (do a search for more info).

Is it possible to see a modified version of that graph with rpm instead of speed ?  I'm interested in the response of the 2530's but I'm not sure about the GTR gearing.

Dyno's charts are done in either 3rd or4th gear which is 21.9km/h per 1000rpm & 28.5 km/h per 1000rpm respectively.

The larger 0.6 AR front N1's are good for more top end power. I have the plain bearing group A's and at only 13.8 psi they can make around 400hp at the treads easy with cams (I have detuned my engine for a safe 370rwhp). If you wack the boost up to 20 psi with a better intercooler you could see as much as 500+rwhp. At those levels your engine needs to be made stronger and even before that an oil cooler is nice to have.

I'm running 700cc sard injectors, cams are tomei 260's and standard airflow meters. The Standard airflow meters run out of resolution over 400rwhp and it's easier to tune with something bigger like the Rb20/25's and they are a straight plug in. If you are shooting for more than 500 then Z32's are the shot. If you have the 0.6AR front N1's you should be able to get more out of it with bigger cams.

i'm running the gt2560r garret 320hp (r34n1) they have 0.60ar compressor and 0.64ar turbine housing and with pfc ,z32afm ,700cc sard injectors and poncams i make 529.4rwhp at 20psi .The gt2560r are very similar to 2530hks with the same turbine but has a differnet compressor ( i my opinion an awesome turbo combo for the gtr).

The 2530 hks is also an excellent unit also.

      A locally delivered Infiniti have remote start installed but don't come with the remote start key. You need a new remote start key and they just need it programed. And this is different to making/programing a new key that just starts the car.

      Cheers, and cheers for sharing so much of the build and also sharing the glimpse of what turns out to bring a lot of us poor decision makers together haha.  I do recommend learning more about how to manage it, if not considering getting a  formal diagnosis.  The discussion with the psychiatrist I got my diagnosis through was quite eye opening, things I'd not even considered to be ADHD related and hadn't mentioned were things she asked about out of the blue and were common themes with people with my flavour of ADHD.   It's not a label for people who are hyperactive and ill-attentive, there's more to it than that and some of it can be much more challenging or damaging - though there are of course two sides to the thing, and a lot of the stuff we have to go through and work on to live with it make us effectively "better" at other things as well. Aside from the fact that there is some argument I could have a bit of ASD seasoning in there (came up during the diagnosis, and neurodiverse things seem to not stay as a cookie cut) I suspect you need to learn more about ADHD if you are puzzled about how hyperfocus could possibly apply.  I *do* personally use "superpower" with quotes deliberately, but it's 100% an ADHD thing due to the exact reason that lack of focus is also an ADHD thing... Loosely speaking the inattentive side of ADHD isn't the inability to focus, it's the inability to control where the focus goes.  Not being able to sleep because brain is more interested in thinking about a stupid thing I said to a girl I liked 30 years ago, not being able to focus on work because my brain is more keen on putting together the torque management strategy we're going to try out with a drag car next weekend, not being able to focus on a conversation with someone I WANT to listen to and respect because there is a flickering light in my peripheral vision.    If I could just stop work and build the torque management setup right there and then I'd not hear anything else until it was done.

      Maybe you should do some more reading.  Google positive effects of ADHD and you'll get your answers.  One of my personal downsides of ADHD has been talking before I think.   Maybe you have it too?

      Excuse me for butting in....but which part of ADHD can be considered a superpower? I would have though it far more likely that some ASD comorbidity is more likely to be contributing to an ability to hyperfocus on something. ADHD being aimed somewhat in the other direction. My shed looks like your shed. My whiteboard list of unfinished projects has entries going back 15 years. I know what you're talking about - I just struggle to connect ADHD to the results being discussed.

      Thanks for reaching out!  It's a blessing and a curse at the same time.  I'm undiagnosed but it doesn't take a rocket scientist to see it in me... I have more half started projects laying around my house, shed, garden, etc taking up space and money, destroying aesthetics than if I added up all of my mates projects together. But, ADHD gives me the ability to hyper focus on things that no mere mortal could even  comprehend.  A recent pool build is an example of that....  I dont know anyone else that would be dumb enough and focused enough to take on then complete something of that magnitude. I call ADHD a superpower but it can equally be completely destructive if not controlled and focusedon the right places. Addiction is a major concern to ADHD people and thankfully my addictions have been no worse than projects, XBOX, chocolate and being an arsehole! It's often hereditary and my 13 year old son is currently learning how to drive it at the moment. Keep lurking! If i can finally finish this bloody thing at some point it will be a win for all of us ADHD'ers! 🤪
