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 .

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!)

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

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
