ahh, so all N1s are R34GTR turbos, but not all 34 turbos are N1s :D

makes sense now :)

>_<

All N1s are N1s - not ceramic

All R34 turbos are R34 turbos - all ceramic

Each N1 had a different variant. R32/R33 N1s are laggy POS turbos,

R34 N1s are the same as Garrett -7

Ive run 300.5kw at the wheels for 7 years in an R32GTR with stock R33 GTR Turbos on 98 and 18psi.

This car is tuned much closer to the bone than i would tune a customers car tho and i now plan to set it up on E85. Ive never found a better power curve than this car at this power level with any aftermarket Turbos so I will not change them. R32 Turbos do fail very quickly tho.

Yea....There are different grades of Inconel so some might be attracted to magnets and others are not.

A better test might be using a multimeter and check for continuity ......Xkalaba you got a meter to check it out?

yeah i've got a multimeter, i can check the set i pulled out, do you know what to look for to tell the difference ?

R34 N1s and -7s are similar but not the same, they have different comp wheel and housing.

gtr turbos

all turbos are listed with specs here

Dont know if your meter has a continuity function but touch the two probes together and turn the selector till you hear a constant beep, then just hold the probes on two different points on the turbine wheel....If it beeps that means that the wheel is a conductor and therefore metallic

If your meter does not have the above function, touch the two probes together and turn the dial to measure resistance(ohms) till you see the display zero off, again place the probes on two points of the turbine wheel and if you see it zero off or you get a small reading it is conductive.

Similarly with either method above, you can touch it on a known metal like the comp housing and you will hear it beep or get a reading of almost zero ohms

Ceramic is not a conductor and will not give any beep or reading

Hope you understand

snap on, so it better have it

thats what i was thinking, but good to confirm, cheers

the N1s turbos have a .64 rear housing and the wheel is bigger to but you need a set of verniers to tell, some have.60 front housing

  • 4 years later...

Pretty sure he knows that part. Can u visually tell if the turbo is different from an N1 or the wheel is different?

Bringing it back,

Ceramics have a 12 sided looking nut on the end of the turbine which is one big piece of ceramic.

Inconel 'steel' wheel rear turbine wheel I have seen them with a 3 sided rounded nut on the end of the casting...

You can see it when looking at the skyline gtr turbo comparison photo on the world wide web...

    • KW only offers a set for the R32 GTR. Popular options are D2 racing, Ksport or Öhlins. I have a D2 Racing coilover set, though I don't know for sure which one.
    • Well, the good news is you have more than one very good option for new coilovers in and around your country. Worth the drive over to KW to talk about GTR stuff.
    • Fair enough, I am in no way a tire expert so I'm not familiar with all the terms and conditions. I'll definitely note down the AD09 to potentially try in the future. Rain is not too big of a concern for now as I will probably only drive in the rain when I have to. And considering I still lack experience driving the GTR I'd more than likely take it easy too. I have coilovers in the car but as I barely got to drive so far I never bothered to even check if they are adjustable haha. The suspension is almost entirely old and worn as well so I suppose when I eventually fix that in the future that would make a huge difference.
    • There's not a great deal to report here .... except ...... FOR .... LSD!!!  I bought a Quaife LSD from the UK and shipped it here .... Wish I'd just bought locally cause the shipping and duty was $700! But there were so many diffs used in the E90s I just wanted to be absolutely certain I was getting the right one so I spoke with a supplier in the UK who builds race cars and they have heaps of experience with the E90s.  I pulled the diff out which was seriously awesome - I've never done anything like that before, I must have watched 1000 videos on YT about it as well as consulting the Bentley manual. It was super easy in the end. The diff was delivered to the awesome folks at Hornsby Diffs and will be back in a few weeks. I also replaced the diff bushings with some Nolathane ones.  Really looking forward to getting it back and getting back to the track or even the skidpan.
    • yeah... the 13kg/mm springs weren't always in there, I had 10kg/mm but doing a few SMSP commanded heavier front springs. It's so good now going into T1 and T2, just need more seat time and real tyres.
