Seem to recall a mate who got his r34 gtt turbo highflowed from gcg turbos for 1700bux but they are in sydney so you could perhaps ship it down?, dont know if the prices have come down.

Any thought on buying a garrett item or hks? tad more expensive but you can always sell your old one to make up the difference.

Depends how much you want to spend really... And if you want a ball bearing or journal bearing turbo. If you supply the turbo the highflowing/rebuilding cost is usually around 1000-1500 if you want to keep it journal bearing. Depending how cheap you find a second hand highflow or even a blown highflow would determine which path to travel. Rebuilding journal bearing turbo's is relatively cheap compared to a ball bearing.. as in 500-600 for a rebuild compared to 1000ish for a ball bearing rebuild.

If you get yours highflowed however you can be guaranteed that your banjo's and oil/water lines will line up... you also build a relationship with your workshop and get a warranty.

I don't know brisbane so can't help you out any further:)

Cheers.

His turbo is already ball bearing.

Yes you can send yours to GCG in Sydney to high flow. I have one. Yes it's cheaper if you can find a blown turbo to send them then sell yours in good condition. I just blew mine so the choice was obvious.

How does a GCG BB highflow compare to a similar sized HKS or Garret item?

Is the difference huge in performance and response?

Does Garret even make a direct bolt on incl. standard dump pattern for RB25?

Last time i looked, GCG was charging $1950 exchange.

i thought of going through the gcg high flow route but iv decided to go for HKS GTRS which is muich more reliable than the gcg high flow and is also a direct bolt on kit for R33

from nengun its 2600 delivered minus the cost of selling your good conditioned turbo

gcg charge 2000 to high flow your standard turbo. so for the extra 300 odd definetely go HKS

Mmm decisions decisions.

What sort of boost can a highflow handle?

GTRS's can easily do 20 psi i hear. Since they are fairly small they would spool to 20 psi pretty quick too!

Now I'm leaning towards the GTRS again...

Go onto youtube and type in hks gt-rs; there is a bloke who posted like 9 videos of his gtst with the gt-rs and it is amazingly responsive, frys the tyres very easily.

it will change your mind on the highflow.

Why rebuild or repair a turbo when its nearly the price of buying one new?. The HKS GTRS will love 2 bar.

:P ummmm for about 3 seconds before it pushes that much hot air it'll melt all 6 pistons.....way out of the GT-RS's efficiency rating.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.

      The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.

      Just like in being 14mm too small (296mm) makes it not fit, being 14mm too big (324mm) it also won't fit. You want to find the correct rotor.

      @GTSBoy Ok so that was the shops problem...they showed R33 rotors on R34 page and i did not know 296 do not fit(and are for R33) Yes i bought "kit" with rotors and pads. Pads are ok(i have GTT calipers front and rear). They have some 324mm but no 310mm. So i dont know if they would fit. I have 17inch LMGT4s So another question. Can i fit those in the rear or they are just "too" big for that?
