Is My Turbo Stock?

Hi all,

I've had my car for a few months now and there are some things which i can easily see were modified. However, I'm still not sure whether my turbo is stock or not.

It already had a manual boost controller installed and it was turned up to max boost, which boosts beyond the reaches of the stock boost gauge. I'm worried that if it's a stock turbo, the turbo can't handle the boost and will blow soon. I don't want to turn down the boost (for obvious power reasons). Are there any tell-tale signs of a stock turbo? I can't see any signs or writing on the turbo without taking it out. It seems to be a bit rusted compared to the rest of the components next to it so I'm wondering if that's normal, or some second hand or aftermarket turbo in there.

I'll put some pics up when i get a chance.

Thanks guys,

Jay-C

Put it on a dyno and find out just how much power its making and how much boost its running.

Dyno opperator will be able to tell you if its safe or not.

If its got well over 200kw and tuner says its safe you can assume that its tuned and has an upgraded turbo, if its making around the 200 mark or less then its a stock turbo and you should turn the boost back to 12 at most.

This is if you fail at identifying what it is for yourself. You really should have asked about the cars full history when you handed over your hard earned coin....

Not sure if this helps you at all, but these are pics from the original owner of my car when the old turbo was done -

Just going on the pictures, you can quite clearly see that the turbine side (exhaust wheel) is much larger and looks to be steel in the after shot. Very confident that if those pictures are of the same turbo and it is on your car, you have high flow job.

Thanks for the responses. Yes, 34GTT i realise that post was for me to get a better idea of what it could look like. I'm not going to be taking the turbo out though so i'm hoping that i can tell just from the housing.

i guess if it says "nissan" on it, it's stock.

No, that isnt totally correct.

You can have the stock turbo high flowed to make more power. So your turbo may LOOK stock, but the internals are far from it.

AS mentioned the easiest way is to see if the compressor inlet has been bored out. :)

Another way to tell is by the cartridge. Often hi flow jobs consist of putting a different cartridge such as a 2860 or 2871. The casting of the cartridge looks different to that of stock, If its a relatively new hi flow, the cartridge will look newer and with less rust.

I sent a stock RB20 turbo off to hypergear to get high flowed, and when I got it back the centre housing of the turbo looked quite different to before, obviously very clean, but also different, so posting a pic of that as well might help?

What sort of power did the RB20 make after you got it back from Hypergear? and was there much difference in the low to mid range response? am considering doing the same.

coz he originally bought it already moded and has NFI?

a couple of the cars i sold were sold on rep, the new owners have NFI whats in them and if they arent in contact with me when they sell then they never will

equally so many people get their cars done at shops and dont ask questions

Am getting it tuned very shortly, hopefully next week, but on whatever tune is running it spools up well, no power after 5000 rpm, but it's got some weird chip in the ECU that will be gone for a Nistune and should make some good power, looking like it will be great value for money, watch the RB20 upgrade thread, will be posting there after the tune, but for the money, so far recommended.

Didn't mean to hijack, carry on.

      R33 headlight relay conversion?

      By GTSBoy · Posted

      Bugger "making it look stock". I put one conventional internally fused Hella relay behind each globe. I just pulled the plugs off the back of the globes and built new loom segments with male and female plug parts to match up to the original loom and the globe, and used the original power wires to each globe coming from the switch through the original loom plug to trigger the relays. Ran a big fat (also separately fused) power wire across the front of the car to feed all the relays. It's as ugly as f**k, but it is wedged down between the headlight and battery on the RHS and the airbox and headlight on the LHS, and no-one ever looks in my engine bay, and on the odd occasion that they do I simply give no f**ks for what they think. Fully reversible - not that you'd ever want to. For f**k's sake. It's a Skyline. They made million of the bloody things. We've been crashing them into roadside furniture for 30 years now. There is a negative side effect to putting relays on the headlights. The coil current is too little to properly clean the contacts in the switches and they get blacked up and you have to open them up every couple of years and clean them manually. I have 25 years of experience on this point.

      R33 headlight relay conversion?

      By joshuaho96 · Posted

      I was poking through the R34 wiring diagrams vs R33 and noticed that the R34 has proper headlight relays while the R33 is like the R32 and sends full headlight power through the headlight switch. I'm not afraid of wiring but I really would like to do this in a way that looks OEM (clipping into open positions on the OEM relay box) and also unlike the factory wiring which interlocks the high beam and low beam on the halogen series 1 GTR headlights I want to make it such that turning on the high beams keeps the low beams on as well. Any advice on how to locate the specific connectors + crimp terminals + relays I need? I was thinking one NO relay for low beams and another for combined high + low running off the factory high beam headlight connector. I don't really want to splice into a crusty old probably discontinued factory harness so fully reversible is my goal here.

      Pretty sure they run the same engine as the Q50 hybrid which specifies 95 RON.  I ran 98 in mine for a while, but it made no difference in performance or economy, so I have been using 95 for the last few years.  I have never hit 6.0L/100km, but have returned mid to high 6 on the highway.  Being a hybrid, fuel economy is a lot more dependant on how you drive it.  At 110km/h, mine never goes into EV mode on the highway, so returns closer to 7.5L/100. urban driving can return low 8s if you are careful or over 10 if you are a bit more enthusiastic on the throttle.

      About a quarter of what you want to do. It's only R7R, not R&dismantle&replaceparts&reassemble&R. ? It is stock. I already told you, you will NOT have broken those. It's f**king 4th gear for Christ's sake. You just chipped the teeth off.
