Garrett Gt3071r Discussion & Results

[BHDave]

yeah, 1 day turn around on my 3071 from GCG. Should be picking it up this arvo.

[-33-]

Yep oblivion, i checked before buying that everything is in stock. So the turbo should be here probably monday i'm guessing (maybe tomorrow if im lucky).

I asked HPIAB and to my suprise they have a "real" GT3071R on the shelf ready to go... and yes it is "a 700177-23 core which allows an off the shelf .63 4 bolt" - to quote morrie. This matches up to the garret specs on http://www.turbobygarrett.com/turbobygarre...T30/GT3071R.htm so FINALLY i've bought it (and at a decent price).

Unfortunately, there's no place i know of in melbourne that does these at a decent price - not that i've looked all that hard as i've stuck mostly to online buying. An mate who actually works for Honeywell didn't give me a better price either. Getting them from America is cheap (especially with the current exchange rate) - but they take an absolute hammering during shipping (don't beleive anyone who says otherwise) so stick local!

what price are we talking about (PM me if u like)?

I got a pleasant surprise when i unwrapped my turbo. It is a genuine -23 cart

And unfortunately even with the garrett turbine housing and .5 A/R cover it still needs a spacer.

But the turbine housing is bollocksing massive! And it's only a .63. All i've dealt with for the last 2 years is my non gated .63 turbine housing and t28 sized ones. This thing is a monster!

The viewers at home would probably like some snaps of the ID tag and that 0.63 A/R GT30 IW turbine housing so they know one when they see one .

Cheers and thanks , A .

Apologies in advance for the quality of the pics. Low light and phone camera aren't a good combo. At least one of the 3 photos of the tag is partially legible....

Out of interest, does anyone know why garrett make the inlet smaller than a regular t3 size? As i have a spacer i'll be die grinding that to smooth the inlet into the turbo, but it just doesn't make sense to me.

oh yeah. manifold to turbo studs are 1.5 pitch where they screw into the manifold but 1.25 on the other end. just discovered that after buying new long 1.25 studs

im not sure either BHDave, but i tired diegrinding the spacer and i was there for ages getting no where, i paid 20 bucks for a machinist shop to mill it out for me after i traced an outline of the real flange size onto it.

goddamnit! This was supposed to be easy!

[Simon-S14]

in theory it is... but bloody hell the spacer, the gaskets, and the rear housing are ALL different sizes when comparted to the exhaust manifold and each other.... thats gay!

[-33-]

what price are we talking about (PM me if u like)?

nah no problem putting it out there:

HPIAB: $1950 ($1750 for external gate)

CRD: $1920 ($1770 for the external wastegate)

APT: US$1449 + US$95 shipping + import duty + GST etc etc

FULL-RACE: US$1149 + all above (didn't reply to any emails).

Looked at ALOT of other places; most didn't have the "real" one, or didn't reply to my questions.

Like i said before, vary wary of overseas shipping of delicate items like a turbo - not only that, you have next to no protection if your stuff isn't right/ get ripped off etc etc.

BHDave I think the reason why the Nissan RB20/25 manifold flange is wider than GT30/35 turbine housings is because they are a split pulse design so probably more like a "Euro T4 twin scroll" housing flange pattern than single scroll T3 .

Brett Lloyd once told me that there is lots minor variation like this and another one is the larger T4 and T4 "International" which some call T45 .

Geoff Raicer (FullRace Geoff) had issues with some housings because they are large T4 twin scroll flange and stud holes but with T4 Euro twin inlets .

The problem seems to come from the fact that Garrett is not one company and different parts of it in different parts of the worlds made different things to suit themselves .

Once we start to mix n match different bits things like this are common .

Cheers A .

That actually makes sense when you look at the area of the outlet/inlet. If you allow for the center divider of the stock manifold it's be pretty close in effective area to the single scroll inlet of the new turbo.

An hour and a half, 1 grinding wheel and 4 beers later i managed to get the spacer flared out to match the gasket. It looks pretty good atm, i'll reassess when i'm sober Also did a trial fit, I need to reroute some wiring or i may have some issues when i hit the track and the housing gets warm. It's a pretty tight fit in an r32.

[Busky2k]

Look forward to seeing the results. There hasn't been much info of these internal gate 3071s on smaller motors!

[-33-]

Picked it up today from the depot...

Its an authentic 3071R, code and compressor housing matches BHPDAVE's above (-5023)... but what's the exhaust housing??? Doesn't look the same!!! Its for ext. gate =(

[Busky2k]

Without a doubt an external gate housing. Take it back or swap with the right one!

haha nice work! yeah i moved my wiriong further up, then insulated with wrap. other then that tho it fits in there nicely!

[BHDave]

definately. There's still more room around the turbo than i had with the old kit. It was also a novelty to be able to access 11 of the 12 manifold nuts with a socket from the top. It used to take me 2 hours of swearing and crawling under the car with an open ended spanner to get the old turbo and manifold on. this time it took me about half an hour. I still spent 2 hours reinstalling the bastard water hose that runs across the back of the head....

Intake pipe and hot pipe are just about sorted. just need to find a spot to fit the bov (stupid type R is too big to fit easily if you want it plumbed back). The front half of the front pipe is tacked up. Will be having a go with the wastegate pipe tonight before doing much more with it.

WELL, i just found out that AVO makes a 0.63 internally gated exhaust housing to suit the 3071, with an RB25 dump pattern... AND at the same price as a garret exhaust housing. I'm looking to put either the garret one (requires new dump) or the AVO one on my "real" 3071 (since i don't want the external gate).

Anyone had any experience, info on these??

[Simon-S14]

it may or may not be similar to what i have, exceopt i doubt the AVO wont will cater for the full 60 mm wheel. I have a cropped 3071R with a GCG cast rear housing (OP6 copy) which meets up to rb25 dump and manifold. it is a 0.71 AR. i just dynoed it the other day with cams in it no and made 290 rwkw on 1.2 bar.

personally i think 0.63 is too small for a 25
