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?

    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks  
    • Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..
    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
