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.

    • Didnt realise RB's had more then 1 head.
    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
