I am wndering if any of you turbo guru's out there might be able to enlighten me on if this seems like a good idea?

Now the GT2860RS discopotateo has had a good rap from what I have heard especialy on an RB20.

Now I am asking this as my brother unfornately became another victim of the ceramic wheel of his vg30 turbo that was on his RB20 (R32).

So we were thinking of doing this for a few resons.

1) The turbo will still look stock

2) The disco potateo seems to be a sweet turbo on smaller displacement motors

3) The vg rear housing will loosen up the power at the top end.

Now will this make it too laggy down low?

All so could anyone out ther be able to tell me what the A/rs are for the rear housings on the 3 different sized nissan turbos. (VG30/R34_Rb25, RB25, RB20).

Now I don't know alot about turbos aprt from there basic pricipals etc so I am sorry if I sound silly. :P

Thanx guys. B)

i should only be as laggy as the vg30 turbo with the highflow as the A/R is the biggest factor of when it will boost.

did your bro find it laggy with just the stock VG30 turbo?

The vg30 turbo was a stock turbo not a high flow.

It came on round 500rpm later than stock turbo but it was only on the car for about 5 mins and it spat the ceramic wheel at 10psi.

Bit of a bugger but thats life.

Send it to GCG for hi-flowing :P

Works wonders for the VG30's as the rear housing is bigger than R33 turbos :mellow:

Thats my thought anyhow.

It'll be a little come on later, i mean going bigger generally speaking does that.

But the use of cams would offset it a little, and he's be into the 200rwkw range easily

send it to turbo australia, they graft a complete garrett ball bearing core into the stock covers. makes easy power with buggerall lag and you get a brand new core rather than one of those rebuilt cores that gcg sells. costs around $1500 but for what you get its worth it.

im talkin about when you put the discopotatos internals in.

should only be as laggy as the stock vg30 turbo, maybe a bit heavier due to heavier/bigger wheels

Ahhhh Ok Kool.

Sorry Misunderstood u there mate.

Sweet.

I would dare say that would be the path we would go down.

A new core would be the way to go I guess.

    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.
