I found this by pure chance and it has some usual features .

I'm not sure which comp wheel this one has but will look around , Brett says that one of them uses the 76.2mm 52 trim GT37 compressor - same as the 3037 52T .

Possibilities in altered form , cheers A .

I'm pretty sure that's just a normal off the shelf item from Garrett.

Very overpriced too. They're at least a few hundred cheaper locally.

Who is Brett?

Have to agree, that looks a little old school and at 500hp rating isn't worth it. Still prefer the 3076 in anti surge configuration. The problem with these things is if nobody has tried it then what if you strap it on and it gives up the ghost at 250kws. Or ends up a laggy 3040 type turbo. That price looks a little high as suggested to, do yourself a favour and go to the ATP turbo site in the States. Got all my stuff there and is cheap. Then again, buy Australian and if you get it all from the one place maybe a discount is in order. As I said in my PM Adrian, just go with the .82 exhaust option and if you try this turbo, who knows, it may work out. I am not into external waste gates but then again as we've discussed the 63 housing with a 50mm waste gate should give you the best of both worlds. Still prefer the bigger housing though.

Brett from GCG I believe.

Only relying on memory here...but doesn't the 2876 use a 52 trim 76mm comp wheel/housing - which may be the source of the compressor side of this setup.

Late Edit: Actually no, I just checked and the 2876 uses a 48 trim 76mm comp wheel and .70 comp housing - close but no cigar.

No a GT3071R has a GT30 turbine (normal or cropped) with a 71.1mm 56T compressor wheel .

A GT3037S is a HKS marketed GT3076R having a GT30 turbine and a 76.2mm GT compressor , "S" in HKS's case means with the port shrouded compressor housing . The plain inlet snout ones are just called 3037 or GT3037 .

Doesn't matter anyway because that turbo in the above link is the wrong comp wheel style so no good .

Got the spies looking for either the right turbo or at least the right cartridge which appears to be available .

So much choice. Well, look at the bright side, 10 years ago things were mighty different. To3 or To4, take your pick. Hey Adrian, what mods have you got so far ? Your not planning on cams or going for a rebuild are you ?

Just about to call you , hopefully talk this afternoon .

BTW I followed a link from an SR site to a HKS Japan site and this is what they say about their 3037 52T kit for S15 Silvias inc supposed dyno graph .

Now I know an S15 SR20DET is very different from an R33 RB25 and my guess is that an unopened late SR20 would be in a pretty soft state of tune . Can anyone who reads Japanese tell me whats been done to it please .

Funny you found this, I have been speaking with a reputable garrett turbo wholesaler in South Aus and was talking about the Garrett GT3076R.

They have 2 types that they sell, one is the GT3076R with anti surge compressor housing and .82 ext gate rear housing to suit, Trim is something like - 57 comp wheel, 55 turbine wheel.

The other is pretty much the same turbo with the 4" bell mouth compressor housing like the GT30R, with .82 ext rear housing - trim is 54.97 comp wheel, 53 rear turbine wheel.

Priced fairly differently, would there be an issue going with the GT3076R without the anti surge housing? all supporting mods looking for around 270-280rwkw.

Do a search, but I remember reading somewhere that some [note not all] users were experiencing surge.

I have the 100mm port shroud 'with all the supporting mods' and have not had any issues, but it depends on too many things to say that this will or will not happen.

Defining 'all supporting mods' is a key issue.

      Unpeeling the Orange

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.

      No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).

      I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
