Hello all,

I have for sale a GCG XTRGTST-S1 turbo for sale. It's a stage 1 high-flow from GCG. As far as I can tell, it has steel wheels front and back, and is ball bearing.

The turbo is "plated" with the following details, and has GCG written all over it:

S/N: 016085

P/N: XTRGTSTS1

The compressor housing is labelled 16V 12 (R32 housing)

I had this turbo recently running on my R32 4 door. The turbo has no visible shaft play. It ran very well, but was laggier than stock. My mechanic and I agree that this turbo would be a good choice for an RB25DET, or an RB20 with alot of top end power.

The old owner of the car claimed that the car was dynoed at 187rwkw @ 15psi with NO aftermarket fuel system whatsoever. The turbo is rated at 450hp. The turbos are claimed to handle in excess of 20psi with no drama's.

Price Drop! Now going fro $1150ono

Contact me preferebly via PM, or e-mail. I'm located on the Gold Coast.

Can get better pics on request.

Hey mate, how much more laggy was this then the stock turbo? Any idea when it made full boost, is this just the same as the GCG stage one hi flow thats $1950?

Also any idea on how many kms the turbo has been used for?

This is the same one that GCG will do for $1950. It would be the exact same as taking your R32 turbo to GCG, except alot cheaper.

This turbo is laggier than stock. I had a badly un-tuned R32 RB20DET, and I would make full boost (15 psi) at approx 4300rpm, with a stock fuel system. This turbo's efficiency point is somewhere like 6800-7000rpm, and can go higher than 20psi, so thats where you'll be seeing your peak power.

I would recommend this turbo to someone wanting more top end power, as the midrange isn't the best around. This particlar turbo woulds perform much better on an RB25.

I can only guess at the amount of kays this has done, but i'd say 12,500 wouldn't be far off. Turbo has zero shaft play.

As above, and you might wanna change the price in your first post and add a 1 in there somewhere :)

Thanks for letting me know mate :)

so what sort of power would u get on an rb25?

~240kw? would the midrange be better on a 25?

265 rwkw with Tomei Poncams on an R34GTST

275 rwkw on an R33GTST with the slightly larger VG30 turbine cover (maybe worth 10 rwkw extra)

:laugh: cheers :O

Thanks for that SD. I think it does actually have the VG30 turbine? (if not it looks like an R34 item)

As you can see this turbo can pull some nice figures at a good price.

    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
    • @GTSBoy yeah sorry i know thery are known for colors bud those DBA are too in colors 🙂 Green will be good enough for me
