what size rear is that with mate?
I just bought myself this a few weeks ago.

Some people i have been speaking to in the SA section say that this turbo is too big for a RB25, and that it is going to be real laggy. But i wont really know for a few weeks till i have it installed. That is the 0.82 rear housing i think, it has it stamped inside somewhere.

With that ^^

Old mate its not a full turbo its just the housing

I believe its the .73 AVO recast nissan housing

I swapped it for the .82 external Grant

so its still the 3076r but now external gate

Is this the twin scroll version that you guys have been using?

I previously had the 3037R which looks identical to the first pictured so called T04S at the start of the thread. It lasted 6 years running 17 or 22 psi and making 250-270atw before having any probs. It dropped a bearing. You guys were saying its crap at the start of this thread but i disagree. I had very good results although it does lag a bit which would be my only complaint. It hit full boost around 4-5k on an rb20 w/ext gate...which are renowned for the lag so it would prob come on alot sooner on a 25.

Anyways, i'm considering getting the 3076R instead of another 3037R due to the twin scroll factor but i'm still unsure. Would this turbo reliably handle 17psi daily and 22psi of boost on and off? Anyone have any experience with this turbo on an rb20? The results look good for rb25's.

Sorry to ask in an rb25 thread...just dont wanna start a new one.

Cheers.

Well for a start the first one isn't a 3037R or 3037 anything . To be a "3037" you need to have a GT30 turbine and a GT37 compressor wheel .

The 7/14 bladed wheel is not a GT anything , from memory its either a T04S or a 76mm TB41 wheel .

The second one is what you could call a 3037"S" , I believe S is the designation HKS gave their spec Garrett turbos in the GT30 family with port shrouded comp housings and 76.2mm GT37 compressors .

My front housing looks identical to the turbo in the 1st pic and mine is a 3037R. Was just saying. Mine is a 6 year old turbo and looks different to the current 3037's. The turbine wheels are front 7 blade and rear 10 blade. I cant measure them as they are munched :)

Have any of you guys had any experiences with 3076R on a 20?

No that one two post above isn't it either , that thing is called a "GT2876R" because it uses a GT28 NS111 turbine and a 76mm 48 trim 7/14 bladed compressor .

The first one in the first post said 60mm by 55mm turbine so it wont be a 53.8mm GT28 turbine , those are the approximate dimensions of an 84 trim GT30 turbine .

According to my lists there are 24 Garrett and HKS spec units in the "GT30BB" family . For these there are only 9 cartridges so to make up those 24 the variations are in the housings .

A couple of years back I typed out most of the GT30 BB range and posted them on this board .

Cartridge wise there are only 3 "real" GT3076R's or you could call them GT3037's because in the real versions terms it means the same thing .

The most common is the largest compressor trim version or GT37 wheel family in 56T , less common is the GT37 52T version , and quite rare is the GT37 48T version . So all the same 76.2mm dia GT37 or BCI-18C wheels with 56/52/48 trim variations .

They all use the same ~ 60mm GT30 UHP 84 trim turbine in these "REAL" 3037/GT3076R turbos .

56T cartridge 700177-5007 , 52T cartridge 700177-5006 , pretty sure the 48T cartridge is 700177-5005 .

Complete units (minus turbine housings)

56T 700382-5012 - with Port shrouded compressor housing . 700382-5011 for with std comp housing inlet .

52T 700382-5010 - with PS housing . 700382-5009 without .

To be confirmed but 48T unit is said to be 700382-5008 and non PS comp housing only .

Not using the force , the 56T ones are easy to find and the 52T I own .

A .

discopotato03...I'll post up my serial number off the garrett plate on my dead 3037R to compare to your list. I'm curious now to see if it matches anything. Maybe a certain workshop who did the work did a dodgy on the old owner telling him it was a 3037 cause thats how i've been led to believe it. I also have the receipt from this workshop.

Also i recently emailed garrett to price up a 3037R with my serial number and he said it was superceded to a new number. Will post up the new number also. Now the just gotta find the email. Thanks for the very indepth reply disco :P

      Another little story of weird shit happening

      By MBS206 · Posted

      Ha ha, yeah, I've had one following me around in my parts boxes since about 2007 I believe. Just a little iddy bit hole drilled in the one I have to let it vent out once pressure was removed from the engine side. Still no idea what I'd put it on, ha ha.

      Anybody affected by the M1 minefield this morning?

      By MBS206 · Posted

      Just read this... Just a little bit of a wild one! Do you think the driver was testing out a new feature/device for how to lose the cops in a high speed chase?   I also suspect, if the box has a road sweeper that does magnetic metal pick up, he does a LOT of work in the machining industry. Which is what most of that looked like, machining chips from a mill or lathe. And I bet they're RAZOR sharp! And from an environmental perspective they really do need to actually collect all of those little pieces too. I wonder how many people still cop flat tires over the coming months on that road?   As for insurance company, yeah, it'd be interesting to hear what they say to the owner. But realistically, he's right, that "It's his fault". In the way that, it was his truck that spilled it, so they need to clean it up. However, neither he, nor his insurance company may bear the end cost if they do an investigation and find out it was caused by someone elses negligence (And they know who)...

      Yeah, no matter what bad things people can say about Julian from Autospeed, he at least was capable of thinking and his inclusion of a check/relief valve in the plumbing for the Audi boost controller, that I made a copy of and used for years**, completely eradicated that problem. **It's still lying on my workbench where I put it about, um, 18 years ago and have never found a home for it!

      New fix for low tyre pressure from bmw

      By MBS206 · Posted

      I didn't actually know this! I've seen photos of the H1, mainly outside shots, and they just look "different". I guess there'd be a few little changes like nicer rims, and probably the fact they have nicer looking paint with some depth and shine, which will make any vehicles body look different to the very flat colours of the defence force.   I've watched the guys on GHPC convert their Humvee to LS1, and they've done some really nice front shock upgrade. I'm waiting for the next video on it with the rear end done. I can't remember if they've already done it, or I dreamed it, but I believe they're also supercharging theres. They will be in the future doing proper long travel suspension too.   If you ditch out your big V8, as rubbish as it must be, send it to my place. I'll let the unreliable V8 motor and box be here. I just like V8s... So I'll find something to do with it... Even if that something is just taking up valuable space in the yard. I might have something Skyline I can send back in payment... Or even Ford Barra motors  (From memory you're in Canada yeah?) So you can then play with the legendary Aussie 4L version of an RB...  Except they don't have that distinctive random miss at idle like the RB25 does.

      Or you mean the age old problem of early 2000's manual boost tees, where they never let the pressure out of the line between the boost tee, and the waste gate, so after your first trip on boost, the damn wastegate liked to stay open and be laggy on gear change?
