Nope Racespec your wrong , go and have a look at the old Garrett Cataloge PDF . Cartridge or CHRA no is 700177-23 . Its also shown in the new cataloge (turbobygarrett) BUT only in the comparison sheet . Its the third of the three GT3071R types listed as 420 , 425 and 450 Hp . This is a generic cartridge that you option housing kits for if it comes from Garrett . ATP will sell a complete unit with optional housings .

No one has offered it yet but there's nothing to stop you using the comp cover off the GT2871R 56 T which is .60 ARR T04B .

700177-13 is GT30 turbine + 76mm 60Trim T04S compressor .

700177-14 is GT30 turbine + 82mm 56 Trim GT40 compressor .

Cheers A .

I've got a GT30R To go on a RB20 and I am abit worred it is going to be to big and laggy???.

Specs are .7 front cover 58mm wheel and rear housing 0.63 56mm wheel.

Dont know why i was sold such a big front cover? and it is internerly gated,

Any one got any idear when it would come on boost and what have other people got on there RB20's, what kind of power will it make-230 or so on 1 bar?

It would be great if any one could help me out, Thanks

hi tarek

that pdf i sent you a few weeks ago has the GT3071R version that disco is referring.

No problems. With the gate fully open, the most boost it will make is 4psi, max.

dude,

that's no good. if you're making boost with the gate completely open, then there is a restriction on your exhaust side, maybe the VG30 exhaust housing doesn't flow all that well when matched with the GT30 turbine.

what should I look at to correct this? Maybe drop the cat for an initial test?

Maybe the wastegate hole isn't big enough?

Mafia,

having a look at the exhaust system first off would be a good option as this area has been found to restrict engine power and turbo gas flow.

if this doesn't help, then maybe look at the wastegate exit area on the turbine housing.

Hiya all,

Got a Stagea RB25DET with Attessa 4wd system.

Currently got 141kw at the 4 wheels, currently upgrading intercooler, entire fuel system, and afm at the moment. Im after around 200kw at the 4wheels.

Opinions on GT30 turbos for the RB25... which would be best, for a heavy wagon which is used for the family car, as such. Either a full rebuild of my standard R33 series 2 turbo, with full GT30 internals, from ATS for $2100 in liue of the GCG rebuild, or the GT3071R as per spec below......

Opinions? Thanks heaps ppl's, Brendan

(ps - this turbos are on ebay for $1700aus)

GT3071R (84T) with internal wastegate 430-450 hp

Turbine:

-56.5mm w/ 84 trim

Housing:

-0.64 or 0.86 a/r (GT28 inlet and outlet flange)

-Internally Wastegated (No Actuator)

-T3 5 bolt discharge 0.63 and 0.82 A/r available shortly Email us for ETA

Compressor:

-Wheel: 71mm w/ 56 trim (GT30)

Housing:

-.50 a/r TO4E

-Inlet: 2.75"

Do us a favour and email them for the ETA on the internal gate .82 a/r???? ;)

The seller is on ebay, known as "Roguepi" located in Sydney....

I thought it was an intresting price at $1699 plus delivery, brand new, and there are 4 different spec options at that price.

But wondering if I'd be better off rebuilding my 'spare' series 2 R33 turbo upto GT30 spec for an extra $400. (Spare as in I got jipped by a forum member stating that it was a R34 Neo turbo - bugga, big bugga!)

  • 1 month later...

i am waiting hear some thoughts about the "ultimate wastegates" from a turbo dealer that has ordered one.

cubes, are you sure a GT3071R would only get going at 4500rpm?? i would have banked on them being a pretty neat match with ok response.

Doesnt get going until 4500rpm on a rb25det.

Looks interesting, I wonder how it really flows :S

http://www.atpturbo.com/root/releases/release103105.htm

Hmm interesting indeed. But lit looks as if the tapering may introduced some turbulence in the wastegate gases?

Edited by Busky2k

there will be turbulence for sure, perhaps not dissimilar to a combined dump. however for simplicity if there is no substantial drop in performance (granted there is some loss) this might be a neat and easy solution.

does anyone know exactly the cost to performance of combined vs split dumps?

Hello All

JUST SOME UPDATED NEWS for you all

1.

I have ordered the ULTIMATE WASTEGATE, to have a look at it, they have been behind in production, its been sent, should have by the end of the week

This actually only suits the ATP housings that they have cast up

2.

T3 Internally Gated Turbine Housings SHOULD be available in MAY

3.

I have a BRAND NEW VG30 Turbine Housing being cast up here in SA, ready for production late JANUARY

Thanks

Tarek

    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
    • OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
