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).

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 ?

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?

      While doing my tailgate struts I found some rust. Also replaced my bonnet struts. Such a cool satisfaction with that job.

      Should I use rust converter on this?

      By PranK · Posted

      So I removed as much as I could from both sides. The shop vac did a great job of clearing 99% of it. I got it all as clean as I could and then absolutely drenched the whole lot in the rust converter. Tonight or tomorrow I'll hammer it again. The cavity must be close to 400mm in length and surprisingly I was able to get it right to the back.  I'll quickly reassemble and then pretend I never saw it. I'll post pics (for me to ignore later) soon.

      Help Understand GTT Boost Setup

      By GTSBoy · Posted

      I have always resisted the urge to go silly. 8" wide wheels and street friendly spring rates? Check. (Let's not talk about the steadily increasing spread of spherical joints across my suspension!!) Stock turbo, run at 12 psi? Check. Lasted for~?10 years before it died. Highflow put on rather than seizing the opportunity to go G45. You don't need 300 rwkW, let alone the more massive numbers that seem to be essential these days, to have a car that is already way too powerful and fast for a streeter. ~250rwkW is fine. I've never exceeded 200, although I will sneak up above it if and when I manage to get my finger out and do what needs to be done to use the highflow's capacity. You don't need $10k worth of CF bits glued onto the outside. You don't need razor sharp ankle cutting front splitters. You don't need the car to be 2" off the ground. You don't need flawless paint, mirror finished wheels, brand new indicator lenses, etc etc. All these things just make the car impractical and will cause you pain when they get damaged, which is inevitable for a street car. A few nice additions are good. Good seats are good. A nice stereo is good. A/C is good! (46° on the road yesterday and my A/C is degassed again. Was moderately traumatic driving home!) The main reason I stick with a mildly modified old Skyline is that I have had it for >25 years, the mods are the rolling result of 25 years of things dying and being upgraded opportunistically, coupled with a few "just 'coz" ones. And I hate almost all modern cars. If I was a young buck starting out now.... I wouldn't bother. Cars have a few years left where there is any possibility of interest or fun. Thereafter there will be no such thing allowed or possible. Any time, money and effort spent now on a project would just be a waste.
