New Garrett 3071R experiences..

[discopotato03]

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.

<{POST_SNAPBACK}>

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"

[Cubes]

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!)

Actually there is a Garrett Ford style integral gate .82ARR T3 exhaust housing . ATP offer one as well thats supposed to be like a GT30 on the inside .

[BookyVL]

So, has anyone actually put one of the new Ford turbo's onto an RB25DET?

Interested to find out how it went because i just found one I could buy...

Thanks

[Cubes]

Doesnt get going until 4500rpm on a rb25det.

Looks interesting, I wonder how it really flows :S

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.

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

Edited December 19, 2005 by Busky2k

[wolverine]

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?
