Did you end up going with the GTIII SS? What were the results and how are you liking it?

Life has an interesting way of distracting me from projects. I basically threw them on and I've been running wastegate boost on the stock tune. Response appears to be roughly the same as stock R32 GTR ceramic turbos. If you want a ball bearing CHRA and more power capability I think the Nismo R3 turbos were probably the way to go but they're discontinued now after being sold for like a year at best.

Yeah with the exchange rate these GTIII-SS are tempting, about the same price as the -9s...

When I look up -9s these days some suppliers claim they're discontinued by Garrett. I don't know what the truth there really is.

They're such old tech that every Taiwanese/Chinese knock off turbo manufacturer has their version for sale anyway.

The interesting thing about the -9s though was the ceramic ball bearing, at least the 836026-5002S.

And id still take the -9 over the new hks turbos

-9s aren't a bad idea if the goal is to make more power, they just have a much narrower compressor map than the -7s and probably whatever TD04HL thing the GTIII-SS is.

Um, OK. But....my Hypergear highflow also has ceramic BB core. That's just come from some Taiwanese/Chinese factory. It's not like Tao builds the cores himself in his own foundry-factory. It's not rocket surgery any more.

I hate to interrupt, there are enough internet rumors. I do build every single CORE in house that leaves my workshop including the one that you are using, as well as engineering work done on your turbo housings.  Reason been is I got shafted badly by a turbo joint 18 years ago when the business first started. I since trusted no one when comes to selling anything under my name, or I just don't touch them at all.

Oops. Sorry mate.

It is both excellent to hear and also surprising though. The amount of work required to (effectively manually, not on a production line) build a core vs your low retail price point is why I presumed that you were buying cores.

But let's also be clear about what is meant by "build". At your price point I can't see you making cores from billet on a mill, even if CNC, or doing all the machine work on a rough casting. Surely the lumps of metal are sourced more or less ready to go from an Asian supplier, right? Maybe the same with shafts. I mean, you could turn shafts up yourself, but it's pretty slow going for items that are all essentially bulk order producable.

I was always perfectly willing to believe that you assemble your wheels to shafts, fit up bearings and do all the balancing. I actually expected that you would have been doing all that even if the core did arrive from a supplier with most of that pre-assembled.

Nevertheless, please accept my apology.

Well, I do turn bearing housings, shafts and wheels on special orders, so you can order any wheel sizing preferred. Parts came from every where obviously, came from reconditioning turbos and been shafted, I know exactly where certain manufactures would stuff up. It sounds like I'm just assembling cores, but importance is I get to check if all parts are made to specs, if castings are right, all clearances and runout are right, balanced ok, bearing pack sounds before passing onto clients.   Building test cars, doing dyno testing and sponsoring drift cars is all parts of QC, so I get to know how a particular package performs before selling. 

Yep, its slow and ineffective way of production, but I prefer less headaches.

    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
    • Well they got my money but they are not getting my gearbox ! 
    • It's needed for rolling idle up, and I think it is a decider on VCT also.
    • I mean, not really. Link ECU's can absolutely still have errors from the ECU thinking it's getting a sensor it's not expecting. I would imagine the speed at the ECU level in Nistune does absolutely nothing anyway? I assume the ECU does not do any fancy TC stuff with regards to front+rear wheel speed or anything of that like anyway. Someone who uses Nistune may be more fluent in it. 
    • Not yet quite as bad as what we've seen a Jim Berry clutch do in an R32 GTR though when it decided to cut a chassis rail in half... Still very very gnarly and a great reason to avoid.
