What Turbo

[p055um5]

Ok it's time to bit the bullit and upgrade the turbo on the old girl (wish it was this simple with the wife).

Does anyone know of a direct bolt on in the Garrett range of turbos (full model number please and or website) Will except another brand name turbo as well.

Garret dont make a Mitsi flange bolt on. Some other companies do make custom exhaust housings that fit to Mitsi flanges and take a Garret core.

PTE (Precision Turbos) and Bullseye come to mind. If you do a quick google there is tons of info on those brands.

FYI, I am running a PTE SCM 6152E (Basically a GT35) on my other car, its just a sleave Garret core, but there is a BB version.

Any point sticking with the 16g and high flowing it? Has anyone done this and had reasonable results?

I understand this is out of the question if you're chasing big power, but just putting it out there. (I'm guessing with your bottom end though possum, a high flow would just be a waste ;-))

Motor Build

Yes motor is biult for 500hp plus and gearbox diffs and anything in between has been rebuilt. Just need a Good turbo, I also have water/meth injection so big number can chased, but down low below 3000rpm i want economy at present 26mpg with afr 13.5 and tring to get 30mpg up around 14.7 to 1.

Only want 350 to 400hp at motor.

 

[to4garret]

economy below 3000rpm means no boost

might as well go for something largish, i went from a 16g, to the pte i mentioned above and went from 330kms per tank (45l) too 480kms, mainly because too "hit boost" i need 4000rpms+ and a few hundred metres of clear road atleast.

My 16G has been high-flowed and converted to Ball Bearing. Achieved 226kw running 18psi.

Hey dude, cheers for joining up to the forum, who did the work on your turbo? i would really like to get a highflowed 16g with a ball bearing conversion myself!

It must spool to 18psi at like 2200rpm, i know steve murch made atleast one ball bearing TD05 for a mitsi from hybridising a subi turbo, is this what was done with yours?

What is "high flowed" the term gets thrown around alot but doesnt really decribe anything, does it have a larger compressor wheel or did they port the exhaust side? What was done?

im not sure, that is why i was asking.

Full boost is made about 4400RPM but I do have cams and a different intake. All I know is it was done at a place called MTQ. The mechanic organized it all. The Compressor Wheel has been changed but not sure if the exhaust housing has been ported.

 

[milkandoj]

And what converted to ball bearing lol? why would you bother converting a 16g to bb, they hit like hammers anyway.
Was say a new BB cartridge with larger compressor wheels but a stock sized hot wheel was slotted into the stock rear housing?

 

[p055um5]

Maybe this one

What does the forum think of this one and do you think it will bolt on ok ???

Yeah i was also keen to not only know know if anyone had done it, but what combo they used.... I should have put that in initial q.

It seems hyperrvr has had some good success with his that's for sure! Look forward to hearing more about his set-up as that's around the power figure i'd eventually like, plus it keep things looking 'fairly' standard under the bonnet i'd imagine...

Are you sure its BB? 4400rpm is a bit late dude.

i have a sleave bearing large turbo (PTE SCM 6152E) that makes full boost at 4200rpm, this is also with different cams and intake. Your turbo may have started off as a 16g, but i highly doubt it resembles anything like a 16g, you must have an exceptionally large compressor or turbine to have a ball bearing turbo that comes on that late.

the only hybrid TD05 i know that makes full boost that late is a 25g, but thats not BB.

infact, hyperrvr, if you paid for a BB turbo and it works like the brief description you have stated i would be asking your mechanic for clarification.

do you have a invoice with what was actually done, because that would be really helpful.

 

[something_wild]

Hell yeah, i'd expect even in the most extreme 16g high flow application that full boost would be achieved by the LATEST 3500rpm with a BB core.

I've seen a BB gt30 on a 4g63 at full boost by 3200, fairly standard support mods.
I'm guessing that your high flow is no larger than this, unless as to4 mentioned, they put a huge comp wheel or the rear housing is massive.

How is it on the street, when does it start making boost? Is it laggy/massive difference off boost from stock??

 

[to4garret]

whats high flowing?

Still waiting for an explanation.

 

[something_wild]

Are you referring to me dude??
Okay...... Although i'm more than certain that you actually do know what high flowing of a turbo charger is and are choosing to act ignorant to see how intelligent my reply is, I'm happy to play along and give you the benefit of the doubt and assume you that have no idea. So, I'll give it my absolute best shot to explain the process in a simple way to the best of my ability!!

How's that work for ya champ? Good/bad/indifferent? Awesome! :thumbsup:

Hey who knows, if anything, this might even help a few other forum members out with the basics of high flowing since i probably won't be telling you anything you don't already know....so that's a bonus!

A basic form of high-flowing a turbocharger is the process of taking a standard/factory turbocharger and machining out the compressor housings to accept larger turbine wheels to increase the flow capacity of the turbo, therefore having the ability to make more power on a given motor, provided the supporting mods of exhaust, intercooler, fuel, and managment are all sorted.
In some instances, a whole new front cover is put on to further increase the flow capacity.
As a side note, most of the time a rebuild kit is put through the turbo charger while it's apart which includes all new bearings, seals and gaskets.

There you have it, what a reply huh....?! Gee I've been hanging out so long to write a description of what a high flow turbo is, so thanks for giving me the opportunity bud!

 

[to4garret]

so instead of saying "high flowed" the correct description could be,

extrude honed compressor cover with the inducer milled out for a TD06 25g, 360 thrustbearing conversion on a OEM td05h core and a 15 deg back cut on the turbine and a ported exhaust housing.

The above could also be referred to as a mofidied turbo.

i get all antsy about "high flowed" because it means fuck all. you can not compare "high flowed" turbos because they are all different as there is no description of what has been performed to produce "this high flowing". look at any website worth anything that is selling turbo's and you will see detailed descriptions or specifications or what was done/modified.


if some newbie reads a thread on a forum and see's someone making 260kw atw with 2600rpm full boost and the description was "high flowed" then this person goes to the nearest turbo rebuilder asking for their turbo to be "high flowed" do you think they would get the same result?


I believe the only reason to use "high flow" terminalogy is either you dont know whats been done to a turbo or are hiding the specs for some other reason.


so in summary, "high flow" is a term used to encapsulate a broad spectrum of modifications to make things easier for dim witted bogans to understand, but has no place in technical discussions where we like to share useful information.

Kinda harsh though, seriously.
You could say the same thing about cams.
Some noob comes on see's a power figure and it says 'cams, 272 spec'
We all know there are different 272 specs, yet there's no accurate description.
It's merely a shortening than giving a whole in depth description.
You can always question exactly what specs have been done, but there's nothing against saying the turbo has been hi-flowed...
