Howdy,

Just posting to see if anyone is seriously interested in saving themselvers $$$ and getting heaps more power from their R32 and R33 Skyline GTST's???

I have for sale a brand spanking new GCG high Flow Stage II turbo still wrapped in plastic rated @ 500HP.

"The factory turbocharger is a ball bearing T3 sized unit with a ceramic turbine wheel. In upgrading this unit we replace the ball bearing pack with a new one while replacing the turbine wheel and compressor wheel with hi-flowed models."

Price is only $2000 where brand new they sell for $2450.

Condition is that you have to send me your old turbo or we can work something out personally.

oh and by the way.......I live in DARWIN :P)

Dude..

Please confirm with GCG that this turbo has a BALL BEARING center AND that it is OK on an RB20.

Last time I spoke with GCG in Sydney, the deal was that for just over $2K you give them your turbo and they rebuild it with Standard NON ball bearing center and replace the blades with T3/T4.

AND they have 2 options..

450 hp or the 500hp.

AND the 500hp was not suited for the RB20... something to do with surging due to mismatch or something..

On an rb25 they were both good.

But the main thing is the bearings.. If indeed they rebuilt it with BB center, then that is an awesome price..

However, I didn't think that ANYONE in Sydney had the Balancing tool required to REbuild BB centers.

GCG do have the nessacary tools to balance BB centre turbos, there is no problem using the 500HP turbo on the RB20..the surge they refer to is where the RB20 head runs out of effeciency and instaed of accepting more air from the turbo spits it back, this can be resolved with a port job and bigger cams. With having said that the 450HP turbo is better suited to the RB20 due to its smaller rear exhaust housing the turbo wouldnt be as laggy

watch high performance 4, they go into detail about this turbo upgrade. they use your existing turbo, replace both compressor and turbine wheels with t-04s specs + new bearing pack. and yes, they are ball bearing.

    • Wideband is worth setting up if only for tuning purposes. I would not mess with the ignition system unless there's a misfire. HKS crank trigger is popular out here for the relatively easily sourced Denso crank sensor, not a bad idea to install as well regardless of power level on a standalone. Boost leak test is worth thinking about. Oil pressure sensor tied to a fuel cut isn't a bad idea either. Getting the tune figured out is a good idea. Without putting eyes on it and getting under it there's no way for us to tell you exactly what it needs but most likely you're down to the last 10% that will make a big, big difference in how happy you are with the car.
    • Doing a refresh of my 33 and can see a few websites stating they sell the entire main carpet for our cars, but they all have generic photos which is fine, i understand they are custom made to order.  Just seeing if anyone has got it done or had any experience with this, as i would only want to do it if the fit and finish was as good as oem https://carmatsdirect.com.au/products/moulded-carpet-or-vinyl-for-nissan-skyline-r33-1993-1998-coupe https://knoxautocarpets.com.au/moulded-carpets/nissan/skyline/skyline-r-33-1993-1998/
    • Any plans for E85? If so, add flex fuel sensor.   I'd probably add in the sensors I mentioned above if the Link will support using them for engine protection. With water pressure, you need to be able to effectively set it that "If temp > X, and pressure = atmospheric, shutdown" as at running temp, you should be able to read pressure in the cooling system. If pressure suddenly disappears, it means the water went some where, and this is a quicker reaction than waiting on water temp to go up (Which, can take a little longer than you'd like, considering it now has to wait for hot air to heat it up) Oil pressure, Oil temp, both would be on my list too if you're looking to add sensors. Wideband O2. And at least one EGT sensor. If you're feeling deluxe, put in individual runner EGTs. Single EGT sensor is more so forget about a specific number, get used to "What is normal EGTs", and then keep an eye on it, if it starts going away from "normal" it's a sign something is wrong (Also, things like the tune can still start going out of spec, but EGTs may not show it, for example one injector starts running leaning, so ECU richens everything up, now 5 out of 6 cylinders are rich, and running cool, with one cylinder lean and running hotter, so it's not perfect) Then there is your other things to look at non sensor related, but you may have already done, or have underway, and that would be things like building a sump for more oil, and better oil control under high G-Forces (Cornering, brakes, acceleration). Basically, the above is worth looking/thinking about, if the ECU can do protective stuff with it, and you continue to use it how you are (Drive it to the track, thrash it, drive home, repeat once every 3 to 4 months)
    • Can also confirm these work a treat for most balljoints and bushes. If you have access to a big rattle gun, they make the job so much easier and quicker, compared to using a socket wrench or shifter on the c-clamp 👍
    • Its sort of street but got used for circuit sprints on account of I never drive it on the road because I dont have the time to spare. So it usage was sits around for months at a time then gets driven either 50 or 250 kms to the track followed by 20 laps followed by 50 or 250kms home followed by stuck in the shed until next time. So yeah neither fish nor fowl. Just dont want to break it on the track as a preference. Hence the fairly short sensor/mod list. Probably more worried about it pinging itself to destruction more so than anything oil related.
