Default New turbo.....GT30R-15

Thought I would start a new thread on my new turbo. I had been using the PE1820 turbo on my Type RA engine. The 1820 served me well and produced its rated power. I sold the turbo to Adam from the PDX club and tuned his car with it when I was in Oregon yesterday.

My original plan was to go to a Standard bolt up Garrett in the form of a custom made kit. After the local fabricator decided not to make my pipes after doing another WRX owners kit, I decided to try something else.

I purchased a blown AVO450 turbo on the net. The oil line broke that feeds the turbo so it was toast.. I got it at a real good price though.. I sent the turbo to Tommy at Turbochargers.com for repair. I was at Turbochargers.com last month tuning WRX's and got a chance to see the shop.. Its HUGE and Clean. Nice people too..

I started my rearch out on which GTR cartridge would fit in this AVO .82 housing. The AVO housing is a copy of the Garrett .82 T3 housing but cast with the subaru bolt pattern. It used the T04 Garrett compressor housing and -10 cartridge. The -10 is the smallest of the GT30R centers flowing 44 lbs. The AVO500 is the same turbo only it uses the -12 exhaust wheel. Both of these turbos are pretty laggy on a 2.0. The 450 produces full boost around 4500 and the 500 version is around 5300 rpm. Tommy noticed that the -10 turbine wheel in the AVO450 is clipped.. Why they clipped the wheel I do not know.. There is plenty of meat on the housing to machine out for the -10 wheel.. I think this clipped wheel is the reason these AVO's are so laggy.

What T.com decided what was best for me would be the -15 cartridge. Its the largest you can fit in this format. The limiting factor is the stock diameter inlet pipe. I was pushing limits with the 1820 as far as size of the pipe and clearance to the manifold was concerned already... Because I chose to keep the stock inlet external diamter I limited my self to the -15 cartridge Here are the specs of the -10 vs the -15:

GT30
700177-0010
48 trim
TO4
2.08/3.00 comp wheel size
400hp
44lbs
2.03/2.22 Turbine wheel size

GT30
700177-0015
56 trim
TO4
2.25/3.00 comp wheel size
510hp
55lbs
2.16/2.36 Turbine wheel size


What T.com chose to use was a Turbonetics To4 comp housing. This housing is a aftermarket improved casting of the garrett part. It allows the machining of the housing and gave us more flow.

Final specs of my turbo:

Turbonetics T04 comp housing
GT30R-15 cartridge
AVO .82 T3 exhaust housing.

What I have is a bolt on 55 lb turbo. The 1820 is rated at 38 and I have produced 38 lbs out of the 1820 on my data logs. Since we are using an unclipped turbine wheel and it is much larger I hope to have better spool up then the AVO450... Time will tell. I do not really care about spool up and only top end power for the most part. I want to drive out, Trap 120-125 off the bottle and drive home. This turbo should deliver...

Here are the pics:

Here is the complete turbo:

Stock turbo against my new turbo:




I will get this guy installed this week but must wait for Nathan to ship my Utec back before I can tune it. Data on spool up and flow to follow.. I will be running this with my STI top mount and stock airbox at first as my FMIC and intake pipe have not showed up...

WOW!

what a wonderful thread.... for 2 reasons.

1. its full of wonderful information... which i think a lot of NASIOCers will enjoy this wonderful monday morning.

2. its exactly what i was looking for! GREAT FIND.

i too will be bugging you for updates... because here's my story.

i currently have a 2.4 motor running an SR 40... which is good... but its undersized for mysetup.... its GREAT mid and not so great high... i need a little less on the mid and a ta'ad more on the high end.

so we are looking for a turbo w/ 55 trim and i think 56 will do

bolt on too? wow!

Yayyyyy!

Good luck with that beast!

On the turbine clipping - the AVO500 is spec'd with the full size 2.16/2.36 turbine wheel, according to AVO's website. My XS500 uses the same wheel dimensions according to my calls to XS. So both of these turbo's use a proper un-modified GT3037-10 cartridge, while the AVO450 does not, correct? I thought the GT3037-12 would be the configuration you have now...I'm confused.

The AVO 450 uses a -10 cartridge... Here is the data from the AVO site:

AVO 000-5000-450 $2,750 0.6 48 2.09/3.00 Inch 450 HP 0.86 84 2.03/2.22 Inch


Its clipped... Remove your cover and look.. The leading edge is machined down so it will fit in the housing. Its a shame.. I show pics of this if you link to all the pictures.

The AVO500 uses the same cartridge and housings but... It uses the -12 turbine wheel:

000-5000-475 $2,855 0.6 48 2.09/3.00 Inch 500 HP 0.86 84 2.16/2.36 Inch

I call this the -12 wheel because it is the first of the GT30's to use this larger 2.16 wheel. The 13 and 14 use it also.. The -10 uses a 2.03 wheel...

The AVO500 is the same as the 450 only it has a larger turbine wheel to flow more exhaust. This is the reason it is so laggy. I have no idea what the XS turbo has. I have been told over and over its an AVO turbo rebadged but you where saying it is different...

The AVO500 and XS500 are exactly the same, except for the polished compressor housing. I called XS engineering, and they read me off the specs for it, according to them it has the 2.16/2.36 turbine wheel. I don't see how garrett themselves would be selling a clipped turbine wheel, that doesn't make any sense.

Garrett would not be the one clipping it... AVO or the person that assembled the turbo...

Right, so then what exactly is a Garret -10 cartridge, -11, -12, -13, -14, -15, etc? I think they all use the same turbine wheel, from what I can tell, the unclipped 55mm/60mm.

Cant you see from the data sheets whats different Kevin? www.turbofast.com.au has them listed as well as www.avoturbo.com. All have different trims and flow ratings.

Clark,

Yes, I've been looking at those spec tables, among others and also called a garrett distributer (who was of little help). And lot of head scratching on top of that. The tables are here for those interested:

http://www.turbofast.com.au/GTseries.html

http://210.15.220.239/html/garrett/garrett_garrett.html

I have to fall back on the specs that HKS gives for it's GT3037 and GT3040 - they all use the same 55mm/60mm 84 trim turbine wheel, from the 48 trim GT37 compressor all the way up to the massive GT40 compressor. By searching by the garrett part numbers, I found the following spanish web site:

http://www.turbomaster.com/eng/ball_bearings_eng.asp

The dimensions and part #'s of these spec's match up with the ray hall website, but the naming doesn't. It refers to the 700177-0010 and 700177-0011 as being GT28 based, which makes sense given their smaller turbine wheel spec. Cross checking this with the www.hksusa.com site shows that their GT2835 and GT2835R turbo's use the 2.03/2.22 84 trim (-10) and 2.11/2.22 90 trim (-11) turbine wheels, but with a smaller GT35 series compressors. The wheel dimensions are 56.5 Major / 51.8 Exducer 84 trim and 56.5 Major / 53.6 Exducer 90 trim in metric (mm).

So what does this mean? It would indicate that the AVO450 is not actually a true GT3037, at least by what HKS offers. It is actually a "gt2837", but there is no actual turbo called that. By the dimensions, it is definetely a 700177-0010 cartridge.

The AVO500 by thier specs has a true GT30 turbine wheel in the 2.16/2.36 84 trim size, with the 48 trim, 3" major diameter cartridge. It must use the exact same cartridge as the smallest HKS GT3037, 48 trim compressor, 55/60 84 trim turbine side. On top of that, the XS website says their XS500 is a true "GT3037-48t", indicating it is the exact same thing as the HKS and AVO variants. Evidently this cartridge is not actually any of the 700177-001x part numbers, because it's dimensionsal specs just aren't the same, so it's not a -10 or a -12 or dash anything. It's a 3037 48 trim - period. So the HKS turbos must use their own center sections - the only clue I can find to this is on the spanish web site:

http://www.turbomaster.com/eng/catal...tt&pagina=GT30

I don't doubt that Clark's center section is a 700177-0015, that's a common GT30R part. I just don't understand how this is different than a -12 though, the dimensions seem to be the same.

BTW, for the sake of throughness, the -13 specs a 60 trim GT37 wheel, and the -14 specs a gt40 wheel with a 56 trim.

Here's a couple more links:

http://www.slowboyracing.com/GT%20tu...T_content.html

http://www.extremeboost.com/specials/TurboChart.htm

My brain hurts.

Let's clear a thing or two up.

The AVO450hp turbo for WRX does NOT come with a clipped exhaust wheel. The wheel is as supplied from Garrett.

Why on earth would we clip it?

Laggy? Are you sure you're not confusing 'boost threshold' with 'turbo lag'

Mmm, let me see. 450hp on a 2lt engine... it is what it is. It is not intended for street use, the 450hp and 500hp turbos are intended for track use on 2lt engines, where the bulk of the driving is done above the boost threshold...

And it is what it is, a 450hp turbo. If you want more then buy the 500hp or buy the 600hp+ WRX turbos that we have.

It is designed and intended to do a specific job. The exhaust housing is NOT simply a copy of a Garrett housing with a Subaru flange on it, think about it.

Perhaps you guys should ask your questions of the manufacturer rather than postulating about what is and isn't and what could be.

At the end of the day our turbos deliver, if you want something bigger just ask.

They certainly do, unlike some other turbos (*cough*aps). I can tell you take alot of pride in your turbos, rightfully so.

Given the advent of the 2.5 L sti, do you think you will eventually offer a 52 or 56 trim version of these garrett bolt-ons?

Thanks,

Kevin

Hi Kevin,

The 500hp is a 56 trim, a 52 trim would be a -11 which are very hard to get.

As I mentioned above we also have a 600hp+ WRX turbo but due to the larger comp cover it isn't quite a bolt on.

Anyway, let's see a few people maxing out the 500hp on the 2.5lt STi's before we get too concerned with bigger turbos.

A 2.5Lt STi with a 500hp turbo and supporting modifications to maximize flow would be one helluva street car.

Cheers.
Steve.

For Kevin...

I have done the same research... Funny.

-12 vs -15 is a tough one. I have asked 4 people and I have recieved 4 answers. I was told by someone that the -15 is the current offering and is the "newer" cartridge. It came out later yet is rated the same on most sites. My cartridge is an off the shelf Garrett -15. It is stamped this on the center section on the tag. T.com has a TON of these sitting on the shelf on the GT rack..

Neet stuff. I like learning and I continue to learn more about these turbos each day. This turbo is just a fun project. Its not meant to try to out do anyone. Those days are over and I was actually happy with my 117 traps. I just had the chance to buy a Blown AVO cheap and had the chance to rebuild it bigger cheap. If it works it works and I will keep it. If not maybe I will move on to something else or have a custom Garrett kit made.

Clark

Steve,

You website shows the part 000-5000-475, which we all regard as the AVO500, as having a 48 trim wheel. See the table in the link below below:

http://210.15.220.239/html/garrett/garrett_avo.html

Are you *SURE* the AVO500's now come with the 56 trim wheel? My XS500 which AVO makes defintely has a 48 trim wheel - I took off the compressor cover and measured it. I'm 99% sure as I posted above, that I have a bolt on GT3037 48 trim.

Please double check and clarify this!

Thanks,

Kevin

Steve. The reason why I thought it used the same compressor was on the AVOturbo site it lists the 500 as the 48 trim and gives the compressor wheel size as the same as the -10.

AVO 000-5000-475 $2,855 0.6 48 2.09/3.00 Inch 500 HP 0.86 84 2.16/2.36 Inch

This turbo's part number is 475 but the rating is 500hp. No larger bolt on turbos are listed. Is the AVO500 that is being sold to the US the same turbo as listed above? You mention it is a 56 trim which would mean its the -15 cartridge that I have now. I have held them both side by side and they are different. Can you confirm?

Also, On the clipping. Here is my AVO450's exhaust wheel. It clear shows it was machined down to fit into the exhaust housing. This housing had a smaller bore. I wondered why you would clip the wheel as well. If its not maybe mine was altered in its previous life. I know the previous owner purchased it from SPO(I think thats the right name). Here is the pic:






You can see that the wheel that was in this turbo was clipped and machined down. The wheel that is now in the turbo which is the -15 is significantly larger. Notice how much machine work was needed.

I know there where two versions of the exhaust housing per Jeff S's Cracked 500 replacement. Could this explain why my turbo had what it had?

Sorry for all the questions and thanks for jumping in... I guess we would have come to the manufacturer but you are not on the boards and I only recently found out your contact info from jeff.

Can you give us more details on the AVO600 and what modifications are needed to fit this turbo? ALot of us would be interested!

yes. This is the same conclusion that I made and when I held the 500 in my hands against the 450 they had the identical 48 trim wheel. Only the turbine wheel was larger. It does say 475. I have a feeling some of us have the 475 model and think we have the 500.. I had no idea larger AVO's where available since they are not talked about or listed.

I just PM'ed XT6Wagon, he has a AVO500 from the latest shipment - I asked him to measure it if it's not in the car yet.

Good idea.. I understand it is not on the car so we should know. Also, Jeff Sponaugle has an AVO500. Here are his pics:

Okay...

Firstly.. the turbos listed at http://210.15.220.239/html/garrett/garrett_avo.html

are NOT the WRX bolt on turbos, they are vanilla Garrett bolt on turbos.

If you look in the Subaru section of the website you will notice the WRX turbos all have part numbers beginning WRX- not AVO- .

Okay. The 500hp turbo should have a comp wheel of 2.24inch/3inch... (2.24*2.24)/(3*3) = 0.557 or a trim of 56. The 500hp is a -12.

As I mentioned previously the wheels are as supplied by Garrett, they are not machined or clipped by us at all.

WE machine the HOUSINGS to fit the wheels, NOT the other way around.

In fact if we were to alter the wheels at all the turbos would have to go back to Japan for balancing as there is really only one place in the world that can balance the Garrett BB turbos.

As we already struggle to get these turbos to market at a reasonable price how do you think freight for a return trip to Japan would affect the retail price? It is not an option.

The larger (600hp) Garrett turbo for the WRX requires a LARGE inlet tract to supply enough air, this means that for fitting you either must raise the manifold to fit a large enough hose or '****' or 'twist' the turbo to the side. Obviously this is not full bolt-on and as it is already an expensive turbo before the customization work it's not something we've been actively pushing.

I think that was all the questions. Please let me know if I missed any.

Cheers,
Steve.
