from the information listed on the web page. victory performance says they dont use, the traditional ported 7cm/8cm mitsu turbine housing. but its still bolt to a mitsu manifold and 02. anyone have more information or actually own this turbo.

here is the info from the site

A break through for DSM turbochargers! This is the first of many turbos from the Garrett Performance Product line to be offered by VPE. Not a hybrid but a turbo designed from the ground up to bolt directly into a DSM.

This turbo is built around a Garrett GT30 Ball Bearing center cartridge. The GT series turbos offer new wheel designs that have better spool characteristics and greater power potential than anything previously offered.

The compressor stage is a 60 trim wheel placed into a T04E compressor housing. Maximum flow is 60 lbs/min. The compressor cover has a 3" inlet and a 2" diameter outlet discharge and has been re-designed for maximum efficiency. The discharge exits downward. VPE can provide, for an additional charge, a 90 degree elbow to be welded on toward the passenger or drivers side to work with your set-up.

The secret to this turbo is the new turbine housing designed to bolt up directly to your Mitsubishi exhaust manifold and to the Garrett Ball Bearing center cartridge. If youre lucky enough to already own a VPE O2 housing youll be happy to know it bolts directly up to the turbo as well. Additionally the new turbine housing has been redesigned for improved efficiency. Whats this all mean? More power of course.

Other companies continue to machine out housings and create new ways to clamp the entire assembly together. The new VPE GT Turbo is completely stock in appearance and much more serviceable. Take a look for yourself!

In addition to all the aforementioned benefits this turbo is internally gated! No external WG needed.

Supports 570 Max horsepower and makes an excellent street/strip turbo.

Included with every turbo is our new oil supply line. The supply line comes with an inline oil filter to protect your investment from potentially harmful debris. The oil filter is serviceable and will last a life time.

Everything about that turbo looks good. Kinda falls right in between the l2r and l3r. I just chose those for the ball-bearing cartridge. What about the price?

That's the new PTE exhaust housing. Several turbo vendors will be offering turbos built off of the same exhaust housing. They custom cast them to mate up to the garrett center section & the scroll is perfectly matched to the Garrett wheels. You should start to see most of the major turbo shops going to something similar.

Exactly what Ken said, check this out

Its essentially the same as the mitsu 7cm housing just a custom cast from the ground up that more vendors will be using now instead of the 7cm housings for the ease of use.

what benifit would this offer, when compared to a ported mitsu turbine housing? secondly would a full garrett turbine housing be better if so why?

 

[KenTSIII]

It all has to do w/ the turbine housing design where it meets the turbine wheel. The Garrett exhaust wheels are wider than the mitsu wheels.. therefor the PTE housing should work much better w/ them. Also the turbo manufacturers can purchase & use these turbine housings for alot less than it costs them to get 7cms & have them machined to fit the garrett wheels & then having to come up w/ some sort of clamp to hold the 2 together. This makes everything cheaper for everyone. Gone are the days of the mutt & muttwalk .

 

[2-0turbo]

So is it a T3 turbine housing? Does it use a T3-HF wheel or is there a NEW GT series of turbine wheels? I think it is a little funny how they advertise them as brand new, yet they are using the 60-trim compressor wheel and the TO4E cover. Is is just the center section that makes it a GT? I thought all the GT turbos had the new whiz-bang 3D modeled, super-efficient compressors. Yes? No?

 

[KenTSIII]

The turbine housing "looks" like a normal 7cm housing, until you get to the scroll area & the housing to center cartridge mating area. They can be made w/ either the GT series or the conventional setups. The GT ballistic is the the new more aerodynamic wheels setups & dual ball bearings. Soon they are supposed to be releasing the non ball bearing options.

We definitely need to get around that. Is there a flow advantage/disadvantage, between a full garret turbine housing of similar size and this new PTE housing?

Ken can chime in here and disagree, but here is my take. Given a similar size turbine wheel and housing, the all-Garrett setup is going to be more efficient since they were designed to function together. That always stuck in the back of my mind when first the Franks, then all the other hybrid turbos came out and had XX wheel in YY housing. Seems to work fine in many applications, but I am sure the all Garrett setup would win out over a hybrid any day of the week (given apples to apples comparison). A 50-trim wheel is going to perform better in a TO4E housing than a modified Mitsubishi housing.

I so wish that I would have made the complete switch over to Garrett instead of buying a hybrid. You can get the Garretts all day for $600-800 depending on options. Add a manifold and you are right where the hybrids are costing. The only other hitch is adapting your O2 to the Garrett bolt pattern--or buying one so equipped.

Good point, my question is if the PTE housing is designed from the ground up to work with Garrett turbine wheels. Would that not give the same effect. also I believe 2 A/R sizes will be offered, This seem to be the solution to the garrrett/mitsu bolt up issue. If cost is kept down I see this a being a pretty good solution.

So when are all the other companies going to stop the hybrids and witch to this setup? I was about to bu ya hybrid, but I will wait if there is a better alternative in the near future.

from what i was told from a reliable source in the industry i would wait for the PTE hybrids

 

[KenTSIII]

Yeah.. the PTE was designed off of a garrett housing... it just happens to bolt up to a DSM manifold & O2 housing. If someone was going to go through all of the trouble to custom cast an exhaust housing.. why would they do it 1/2 assed. These hybrids will be in the $1000-1500 range depending on BB or conventional setup. The housing are still being made by PTE & the only ones that have shipped were for testing purposes. I think you should start seeing these actually available for sale in the next month or two.

 

[Slowboy]

Yes, the PTE unit is very nice. However, did anyone notice that picture is not a GT30 CHRA??? It is a standard bearing Garrett... I figured someone else noticed to...

Also, Harry at PTE was not the only one dreaming of a casting 6-8 months ago.... Dare I say that it is not going to be the only casting available?

Ken, have you even seen one of these housings up close yet and compared it to either a 7cm or an 8cm? It wasn't designed off of a Garrett housing at all, except the area where the cartridge bolts to the turbine housing. The rest of it is almost a dead ringer for a Mitsu 7cm. Notice I said "almost". I've had one of these housings in my hands along with a 7cm, both came from AGP. From what I can *see*, it doesn't appear that using this housing will make much of a difference in the ability of the turbo to make power, it may respond slightly differently, but not to say better or worse. I would bet that the 8cm Mitsu turbine housing would flow better than this housing, and hopefully within a week or two I can back up my educated guess with dyno numbers.

So what did the above paragraph end up saying, in short? The PTE housing is NOT "designed" off of a Garrett housing, it was solely to make it easier to bolt the Garrett cartridges to an exhaust housing that us cheap DSM people can bolt onto our cars. If it was designed "off of a Garrett housing" then it would probably look more like a Garrett housing than a Mitsu.

Why would someone cast this housing this way? Simple. There is a market for it. Money can be made. Shops other than PTE will use this housing because it makes it easier on them to put a turbo together, not because it's a better mousetrap.

 

[KenTSIII]

By my best guess.. I would assume that you are Nate Pharr from PA. You really know your #### & I won't question what you say as I've never seen the 2 side by side. I did see the large housing at the PRI show & it looks quite a bit different around the throat & scroll area than my 7cm housing. Haven't compared to an 8cm housing yet though.

Mike,

If you are referring to the pics above, that IS a GT CHRA. If you look closer the rotation is backwords in that pic. Look just under the water jacket, you'll see the tag. It is the same turbo combination that PTE has been taking with them to all the shows, 700177-13. It was on display this past weekend at the Garrett meeting we attended.

Ben,

Thank you for pointing that out!

I did not look that close.......

Does anyone know what they are casting the turbine housing out of?? I wonder of the longevity of the housing from cracking. I liked the looks of the custom one that Robert had.. The stainless was Way cool!! And lighter than a ductile iron.

I know that PTE did the same thing for the Buick GNs and I have heard of some fitment issuses. Hopefully that is not the case on the DSM ones.

 

[JET]

Has anyone heard any more about this?

 

[hostile]

I think buschur is already selling these turbos from precision turbo. They arent the ball bering version but read the br50 at their site.

It seems like it is one from precision turbo.

 

[DrZiplok]

Can anyone comment on the relative merits of buying one of the prebuilt units from PTE, and perhaps how they fit into the "scheme of things"?

To be presented with the option of a BB turbo for under $1k is to be faced with some serious temptation...

 

[Slowboy]

Not so sure they are BB turbos for under 1k........

[doug]

There's a bunch o' turbos listed on the PTE web site for $995 that say they "have been updated with the latest Garrett GT aerodynamic technology". Does that mean they're BB?
