I have got my hands on the latest release from garrett.

i need a 25mm spacer between the turbo and the manifold,

and i need to fabricate a dump pipe but apart from that everything i had for the gt30 will plumb straight

in. I picked the .82 a/r so i will be very interesting to see the results.

here's a couple of pics. looks good

sorry

i just checked and my bad.

8mm is the dump flange bolts.

the t3 base bolts are 10mm.

and yes once it is spaced away from the manifold there is heaps of room.

i will start taking some progress pics when i get home from work.

Is this the internally gated T3 housing that Garrett have been promising all year, and part of last?

What is the used unit beside it? It appears to have a Garrett logo on the compressor housing too.

And most importantly, can you post up the CHRA ID tag number too please?

I'm going to be interested in the progress pics.

cheers

Yes very interesting , hope they are available in quantity !

Dale the CHRA number would be the same for any cartridge with the same comp/turbine so its the complete assembly or unit number you want . Something worth noting is the part number stamped on the side of the exhaust housings mounting flange in the second shot . This would almost certainly be the turbine housings part number .

What I want to know is can these housings be grafted onto the GT37R cartridges because they have the potential to be better than the GT3540R cartridge for the larger/est RB - just need a suitable exhaust housing .

Awesome news!!!!

Out of curiosity.... :(

Do they have a .63 internal gate gt3540?

Hi all , I got to look at a couple of these this afternoon - yep .63 and .82AR ratio .

The Garrett part numbers for the housings themselves (according to the packaging) is 771300-5 for the .82 and 771300-6 for the .63 .

The waste gate flat valve looks to be the same size as the IW GT28 housings and there is room for a larger disc as well . Doing a "high flow" on this valve is common practise on souped up XR6T's so no reason why these could not be modified the same way . BUT - always that but - the greater the area of the disc the more area exhaust manifold gasses under pressure have to work on to try and force it open . I kid you not and don't laugh , I've seen people using what looked like old bed springs trying to keep this valve shut .

The rule is if you run high boost pressure do everything you can to have the exhaust manifold pressure down somewhere near inlet manifold pressure . You don't need massive exhaust manifold pressure to drive the turbine just sufficient gas velocity by thermal expansion .

Back to those housings , Brett at GCG has I think five of each AR size ATM so be quick if you need one soon . Had I been better organised I would have had some pics but no doubt they'll turn up .

Cheers Adrian .

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
