As has been mentioned there are supposed to be a few new offerings on the way from Garrett .

The GTX2971R sounds interesting but the few details available only say the turbine is smaller than GT30 and larger than GT28 . Someone mentioned this turbine being smaller but slightly higher flowing than the GT30 so if its true then it must have less hub and more blade area .

Also there is vague info about a couple of GTW , W for wide I think turbos is plain and ball bearing but there numbers must be using a different system to the usual turbine size plus compressor OD ie GT30 76mm R .

The pics show 9 bladed billet compressors in either T04E or what looks like port shrouded T04S compressor housings .

The turbine housings look like being V Band outlet and inlet in some cases and in a few closer spaced AR ratios .

If people find our more can they post here for all to see .

Cheers A .

Hi Disco potato03,

Sorry to thread jump but i was hoping you could help me out a bit with T04B compressor housing A/Rs.

According to the Garrett site compressor housing A/R has not much affect, not like the hot end of course.

i have some gtx2860r chra's with -5 (0.64A/R) hot ends but need the T04B cold end.

was thinking of using some old GTss housings and re-profiling them to suit the 45.7mm/60mm gtx compressor as the GTss inducer is only 44.46mm and there should be enough meat left to profile it. just wondering on the 0.42 A/R and the outcome on boost rate and ceiling.

Also i have some old gt2510 T04B covers which would have to be sleeved, tig'd either end and profiled as the inducer is 47.7mm / Ex 60.1mm but the housing is 0.60 A/R.

The gtss option is simple but gt2510 a bit more work but can easily be done.

I always read your threads and posts as you really seem to know what you are talking about.

Appreciate your time and thoughts on this.

Many thanks and back to your topic

With a bit of stuffing around a good turbo workshop should be able to make a pair of effectively 2530s (current terminology GT2860R 63T) using the "2510s" comp wheels , from memory "2510s" were just 2530s with smaller turbines .

Gotta run cheers A .

Sorry Discopotato03 you must have misunderstood me.

Put simply 2 identical turbos, the only difference the compressor housings (T04B type) one 0.6AR the other 0.42AR .

Just wondering about pressure rise rate, heat and capacity.

Cheers

Found a lot of good unbiased info on the Turbo Forums, good site. the following one about my particular question.

http://www.theturboforums.com/threads/287017-Compressor-Housing-Size-Effects-on-Surge-Spool-Up

Think i will stick with 0.6 AR and if there is surge (doubtful) then i will re-machine the profiles on my lathe with some 0.42 SS hsgs.

Sorry for the thread hijack.

A few details are now creeping out .

The GTX2971R looks like having the larger or 90 trim version of the cropped GT30 turbine which we know is a flop in GT28 turbine housings . Garrett has been said to have cast new turbine housings that better suit this and the normal 60mm 84T GT30 turbine and I think they are the new V band and twin scroll T3 flanged ones .

Also there is info on the new GTW BB and bush bearing GTW units at ATP Turbos site .

Cheers A .

The $64 question is will they still do T3 flanged IW turbine housings because that's what suits most modest roadies . I couldn't give a rats about V band mounts etc , if it ain't got a workable IW option shove it where the sun doesn't shine .

BW doesn't limit their units to external gates .

The smallest GTW unit could be interesting particularly if it gets the usual GT30 turbine somewhere down the track . From memory it has a 9 bladed 76mm compressor in a modest trim size .

I found a GTX parts list and these details were included .

GTX2967R with 56.6mm 84T turbine

GTX2971R with 56.6mm 84T turbine

GTX2971R with 56.6mm 90T turbine

GTX2976R with 56.6mm 90T turbine .

If you had a HKS GT2835 Pro turbine housing the first two could probably bolt to an RB exhaust manifold .

Maybe, but you'll have stuff all chance of finding a Pro S housing these days I would have thought, and then the issue with the unique dump flange.

Kando sells a housing for the cropped turbine. Might be a better option with external gate off housing.

Seems to be very limited options for internal gate these days (except Hypergear options).

^^ This then poses the question of why not have Stao supply a complete turbocharger spec that has been trialled and proven?

I have no preference/suggestion one way or the other, but reckon for a Garrett devotee an external gate setup on Mark's unit would have been a half decent option even if it no longer resembles a stocker.

Looking closer all that's of any interest in the GTW turbos is the smallest one with the 76mm 58T 9 bladed compressor in the T04E compressor housing . If it found its way onto a GT30 turbine in the GT25 sized BB cartridge (GT2554R-GT3582R family) it may have its uses .

I think the GT29xxR series is a case of why bother without an IW turbine housing .

Agreed. On the add on ATP site it says: "The GTX29R series adds more high flowing internally gated configurations"

Might be interesting to see.

I think Garrett turbos are dead this is their attempt to shut PTE out of the market with cheaper turbos. Only gotta look at their sizing to realize who they are having a crack at!

Kinda sad that a company like Garrett are now literally giving up and attempting to undercut PTE & BW becoming "the poor mans turbo" so to speak :(

Lift ya game garrett and do some f**king homework instead of delivering these "budget turbos"

Thing is with these housing options it still requires other bits to bolt on which still doesn't make them a "cheap" alternative really ;)

Yep, I learnt that lesson the hard way with the GTX3067. After having the dump remade to fit the different turbine housing didn't achieve results any better (arguably worse) than bolt on offerings from Hypergear.

I tell myself I have something a little different at least :)

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
