Ive got a near new GT30 for sale. Turbo has done about 3000kms since new. 0.7A/R front, 0.86 A/R rear. Looks brand new. $1500 firm. Its externally wastegated too.

Its a T3 flange. It will fit on the standard RB20/25 manifold, however, you need to weld a spacer to the manifold so that the comp cover clears the block. Not a huge job, i got GCG in Sydney to do mine. It would be perfect for an R33 engine id say. Yes, i have receipts; not sure about warranty, i didnt ask at time of purchase. It is quite new though.

Nismoid, Im not sure what you mean by the OLDER style TO4 wheel?? As this turbo is only about 8 months old, and is an off the shelf Garrett item i would have thought its pretty new stuff. I was of the opinion that TO4's were old tech truck stuff, but im not an expert, so best to speak to GCG for that sort of stuff. I thought the 0.82 was 550hp and the 1.06 was 600hp.

Shaun.

Nismoid, you have a PM. Please reply.

nice turbo indeed.  

Is this a 500 or a 550hp version dude?

As it has the older t04 wheel i think it then makes it in the 500 range if i recall correctly.

I had exactly the same turbo on my rb20, made 200kw atw easily without pushing all that hard. The big front cover keeps the heat down and makes that awesome hollow choof sound. The front wheel is capable of pushing 550hp worth of air, but its the core design that sets these apart from the old t04's, mine would be still spinning 25 -30 sec's after switching car off! A very responsive (for its size) and durable turbo and at $1500 sounds like an awesome investment for r32 or r33, of r34 for that matter. Wish I could get em that price when I bought mine. Oh Yeah and I have a modified vg30 (to suit gt30) housing with integral w/ gate available for those who may want to put on stock manifold, also a split dump pipe stainless. see my thread.

Yeah, it does take a while to spin down due to the ball bearing core!

Please take note that these Garrett GT30 Ball Bearing Turbos do not have the "older style" TO4 wheels in them. They do, however, have a TO4s (the addition of the "S") trim compressor wheel in them which is the current model GT Spec super duper compressor wheel.

Please dont be fooled by the TO4 thing and its old technology connotations, as this is not the case at all.

And the above bloke is right; it is an excellent price considering the lack of use this thing has had.

Shaun.

Hi Shaun,

Is it the Exhaust A/R or the Inlet A/R that dictates HP rating? I'm very interested but not sure if it will do the job on my new rb30det. I am aiming for a little over 300rwkw. Is this turbo big enough for this target?

cheers

Steve

QQQQ, you have PM. Im sure this turbo will suit your needs and provide excellent response.

All the specs of the GT30 series turbos are provided on the GCG website under technical info and specifications of the GT25 - GT35 range.

Youll also find that these things are $2650 new.

Assuming you mean low mount on the standard manifold, you need the following:

• A spacer welded on the manifold flange so that the comp cover clears the block.

• A screemer pipe welded into the manifold so that an external wastegate can be used.

• New water and oil lines.

• New dump pipe

• New induction piping to suit the 4inch bell mouth

• Modified intercooler piping to the turbo.

It worked well on my RB20, but if i had my time over again, id just go high mount. just my opinion. The turbo is sold anyway........finally!

  • 3 weeks later...

Hi Shaun

Im considering getting a GT30R or a Garrett T3/T4 for my RB20 and just wondering what rev range the GT30 would start getting boost at when you had it on your car?

Ive heard some people say it will not get positive boost until at least 5000rpm?

Is this true?

    • Fark what are the changes of that snapping like that, clean. Nek minnit, custom radiator goes in, with built in oil cooler like those discontinued PWR ones from yesterdeacades ago
    • I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....
    • So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.
    • our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)
    • What are we supposed to be seeing in the photo of the steering angle sensor? The outer housing doesn't turn, right? All the action is on the inside. The real test here is whether or not your car has had the steering put back together by a butcher. When the steering is centred (and we're not caring about the wheel too much here, we're talking about the front wheels, parallel, facing front) then you should have an absolutely even number of turns from centre to left lock and centre to right lock. If there is any difference at all then perhaps the thing has been put back together wrongly, either the steering wheel put on one spline (or more!) off, and the alignment bodged to straighteb the wheel, or the opposite where something silly was done underneath and the wheel put back on crooked to compensate. Nut there isn't actually much evidence that you have such a problem anyway. It is something you can easily measure and test for to find out though. My money is still on the HICAS CU not driving the PS solenoid with the proper PWM signal required to lighten the load at lower speed. If it were me, I would be putting either a multimeter or oscilloscope onto the solenoid terminals and taking it for a drive, looking for the voltage to change. The PWM signal is 0v, 12V, 0V, 12v with ...obviously...modulated pulse width. You should see that as an average voltage somewhere between 0V and 12V, and it should vary with speed. An handheld oscilloscope would be the better tool for this, because they are definitely good enough but there's no telling if any cheap shit multimeter that people have lying around are good enough. You can also directly interfere with the solenoid. If you wire up a little voltage divider with variable resistor on it, and hook the PS solenoid direct to 12V through that, you can manually adjust the voltage to the solenoid and you should be able to make it go ligheter and heavier. If you cannot, then the problem is either the solenoid itself dead, or your description of the steering being "tight" (which I have just been assuming you mean "heavy") could be that you have a mechanical problem in the steering and there is heaps of resistance to movement.
