Well, I'd love to see some real world results from these turbos (ie, not from the manufacturer), there is a lot of doubt in these parts...

Aren't the UP Garage results "real world"? The trouble is I've yet to see anyone else reproduce their numbers at the low-end. With their Spectrum Motorsports DR500 turbos they're claiming 18 psi by 3000 RPM while making 350 kW to the wheels: https://www.facebook.com/upgarage/videos/697436427734626

I still have a hard time explaining away this post, maybe some day I'll be able to get my car on a dyno with a proper tune to figure out if this is remotely achievable:

Was the run with HKS done on the same engine as Garrett?

Not sure it was the exact same engine but UP Garage doesn't really do bespoke builds, they claimed it was all their VCAM Step 1 package and about the same weather. I believe the M7655 and GTIII-SS was back to back though. If you check their site this is what they mention, they probably used the 850cc SARD injectors for those runs but they've transitioned to the Bosch 980cc injectors since then as Denso discontinued it:

So how do you like them? 😄

Apologies for the late reply. No problems with them so far. Of course, singles are a better option these days for outright performance, but I didn't want to lose the original form factor of the engine bay. I also wanted to continue bringing my car to a Nismo Performance Center without many complications.

I have yet to put the car on a dyno, but when I do I'll post the chart for everyone's enjoyment 😉

    • The final part arrived today to un-clampify and simplify the intake Who would have though a 1/2" hose stainless bulkhead fitting designed for below waterline bilge pumps would be what I needed Test fit on a 3" offcut I had laying around to see if it would work, and it worked a treat All going well the intake will be on its "final version" tomorrow 
    • Good luck on the weekend mate
    • Must have been an absolute nightmare to drive when the power steer was out, the rack ratio/wheel size/caster is all set up for power assistance
    • Welcome to SAU, what are you looking at buying?
    • I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
