im running basically same as you with a GCG highflow, but SAFC neo on the stock ECU, makes great power, only run around 13psi. Not sure of the specs of the GCG as I bought it 2nd hand.

I have a GCG turbo with jaycar electronic boost controller. You can make anywhere from 200AWKW upwards (they are rated at 450hp). The GCG is not cheap (although you can get a discount as an SAU member) but they are ball bearing, slot straight back in with no lines to make up and boost hard from low revs.

If money is tight you can run with stock ecu (keep boost down to 10-12 psi).

I was using SAFC, SITC, speed limit cut defender but since you have a S2 you can replace all that for less money with a Nistune rechip and tune. Then you can raise boost to 16psi and really fly (you should get an electronic boost controller at this point).

chat to Bill at Adelaide Turbo Services

he'll line you up with a Garrett GT3076 ball bearing internal wastegate chra, with ported stock front housing, and larger .73 AVO skyline rear housing, bolt on, with lines

best of the best in terms of highflows, and thats a FACT

240kw at 1.05bar (15ish-psi)

cost ?

cost ?

the Garrett BB-IW Chra costs around $1300, the .73 AVO skyline 6-bolt exhaust housing is $700, ported front cover, lines, balancing etc

= $2500 for the kit, bolt on, rated for 280kw

I paid $2200 and gave ATS some spare parts for credit.

similar to a GCG.... i recon GCG prob use a 3071 CHRA.... they seem too laggy to be a 2871

i know its not an RB, but i had a GCG turbo on my SR20 (XTR-SR-3040) and it hauled ass, and didnt miss a beat, made a nice sound too.... like a police siren :P

My turbo does that too. Kinda cool. :)

Just bumping this. Looking at a GCG hi flowed turbo for my S1 Stagea. Just interested what the lag and power delivery will be like compared to a stock turbo? I want to retain as much low end power as possible, so the rpm it spools at is important, some more lag in building up boost isn't a massive issue, but if it only makes boost above 2500-3000rpms that could be a problem.

Also any comments on the mid range and hi rpm power if I intend to only run around 9psi

You will see earlier in the thread that I had one but that was four years ago - there are better and cheaper options now. Talk to Hypergear and he will sort out something to suit you - either exchange or rebuild yours - so no new lines or dumps needed.

Ill certainly ask Hypergear. Just reading through the sites you linked, it would seem the SS1 and SS1 billet machined turbo are the best match for what I need - maximum low end response. Anyone using those models?

    • Well, I'm tired. I'm tired because about 4PM yesterday, before today's appointment someone immediately bought my bumper. They couldn't get it any other day as they're on the way back to NSW. So I had to do that big GTR conversion I had been planning. Unfortunately, the information on SAU about what you need and how this is done is incomplete. So what should be a simple bolt on affair, yeah, it's not. Did you know if you use all GTR items the bonnet won't close? This little manuever sent me into about 1am the night before trying to dodge a way to get it closed. I will have to revisit this in the next few days  - or maybe not, I may let a body shop figure it out. It all needs to come up and my motivation to pull the bumper off is low. It also seems to hit things in the bay where the GTT bonnet didn't. Yes I used 100% new OEM GTR items. Today, I had the joy of driving to the dyno looking like this: Given I had roughed in the fuel and given sensible but pretty conservative timing, I didn't really bet on having the car drive out any real difference than when it drove in. Sadly due to a miscommunication and laptop fun and games (and almost bricking the dongle, prayers and firmware updates indeed), I ended up using HP Tuner credits to licence the car that was already licenced. So in the end my laptop was used. It turns out my butt dyno is still well calibrated after all this time. The 325kw was on 74% Ethanol, the 313kw line was on 98. The other line is the 'before' line which was 281kw. While the numbers are pretty low, they're pretty in line with what you'd expect. Even if US dynos bump the whole result up about 50KW, gaining 10-15% is similar gains.  The curve of the cam is pretty much spot on with what was discussed as well. All this said, it still feels bad to not see the number you secretly want to see. Even if the car drove great beforehand, and I knew pretty confidently the car would drive out much the same way it drove in due to the nature of a wellish dialled in LS1 not gaining much if anything at all from being tuned from where it was. As expected, the car isn't particularly sensitive to running it at anywhere between 12.0 and 13.0 - And the initial timing at 20deg and 12.0 made 308KW. So 3 degrees of timing, and leaning it out to 12.7 for 5kw, anything above stopped giving any benefit until E85 (which has an additional 2 deg as before). Car itself behaved entirely fine. I found out that 100C = 1.15V! IAT at about 7pm was 19C. I might mess with the bonnet mounting.. but given the REO NEEDS TO BE CHOPPED TO FIT A GTR BAR this is possibly something I may leave gathering (more) dust until it returns to paint jail.
    • It sounds farrrrrrr too cold at your place Duncan... Here I was thinking our 10 degrees overnight is getting cold...
    • oh yeah, reminded this morning....bin lids frozen shut too
    • In my case not, because of total reno. But yeah.
    • Did you use an electronic speedo drive? Does you speedometer read all the way to 180km?
