GARRETT TO4B turbocharger

[Billr57]

Would this work on my 250..Rethinking about mounting the M90 I have right now (does not look like I will have enough room under the hood ) so I thought I would go this way.

GARRETT TO4B turbocharger

Compressor- .60 A/R and T5/T6 trim....1.75 ID outlet and 3" inlet

Turbine- 1.52 A/R and P-trim... 3" cross section ID inlet and 2.75" outlet

Thanks
Bill

the comp trim may be alright. youd have to match up you pressure ratio and flow to see where on the t5/t6 map it intersects. but im guessing for a good flowing 250 it may be alright.

The 1.52 A/R in mu opinion is waayyy too big. that thing wont sool up for the lifeof itself unles you are running some serious flow and RPM.

Especially on a 250.

Bill,
I agreee with Emerald...1.52 A/R is way to big! You'll never spool that thing!

Shoot for either .58 or .69 A/R for the turbine side.

FWIW Kelly's Falcon is currently running a .58 turbine housing.

But it's nice to see that you've found religon! TURBO!

Later,
Will

I Thought that this would be easy, but after reading until I can't see anymore. Do any one have a complete list of what it would take for this conversion?

Thanks
Bill

hope I don't become a pain on this subject.....LOL

Don't Garretts say "Garrett" on them?

I have to wonder if it's in fact another brand.

Well you went from one extreme to the other!
Without looking at the map, I would say that you'd run out of turbo by 4000rpm. A 4.1L can pump at lot more air than a turbo that's designed for a 2.3L.
If you can find this same turbo with a .63 turbine housing then you'd be better off.

Bill, exactly what Will said. I have yet run the t3 "super 60" w/ .48 turbine but will hopefully after this weekend, should be almost complete. The .63 or maybe even .82 turbine is way better for the 250. You need to check the compressor maps, it is a must and find out what your engine cfm's under boost will run. No intentions of sounding rude, but seriously this is not something you just throw together, we don't want you to spend more money than you have too (ex. holes in pistons, blown head gasket, etc...)
Do a search on how to read compressor maps, it is a good starting tool. Good luck.

yeah stay away from anything other than a intercooler sold by SSAUTOCHROME their turbos are known to fail within minutes, headers crack same day they get ran, and BOV fall apart.

you can always swap turbine housings too...that first turbo you listed if it is for a good price you could always get a different turbine housing to put on it.

Hi Billr57,

I'm running a T04 on my 250. It has a 1.0 exhaust housing and produces boost starting just before 2000rpm.
I would highly recomend the 1.0 size for good street and strip performance. I have run a 11.4@116mph down the 1/4 using this combination and there is plenty more in it.

A picture of the turbo can be seen here...http://home.iprimus.com.au/chalikouras/

Excuse the comedy!

am I getting closer :

 

[Billr57]

George, you say you are runing something like this?

Thanks Bill

Well, it's definitely a Garrett!

George says his is a water cooled unit; the one on Evilbay is oil-cooled.

Billr57-
contact me, as I have a Turbonetics T04B 60-1 P-trim, with a .69 on-center housing that I'm going to sell.

Hi Bill57

Yes My turbo has very simillar specs to that unit on ebay. I would have no problem putting that turbo on my 250 engine - it will love it.

Like I said, I would stick to a 1.0 or 1.06 exhaust housing!

Good luck

George

You really should do more research before you plunk your cash down.....

People throw around A/R like it is a size or something.......it is NOT.
You need to look at "trim" sizes.

Unless you know what trim turbo you are working with, stay away from it until the seller can provide the info.

Stay away from ssautochrome turbos like someone was chasing you with a stick with doo-doo on it!!

The correct term for the T5/6 trim is T5/6 ... there is no such thing as T5/T6. The T5/6 is good to about 350 HP on a 250.

Think of an A/R rating as a gear ratio.....

You can have a 4.10 gear ratio in say a dana 44 differential on the rear of your half ton pickup, BUT you can also get a 4.10 gear ratio in a Spicer locking differential that is used to pull tandom trailers down the intersate behind 600 HP.

They are both the same RATIO, but they are not the same SIZE...just like the A/R of a turbine housing.

A ratio is a division problem...hence the "/" sign resembling the "A" divided by the "R" with "A" being Area of the turbine inlet at any given point on the spiral and "R" being Radius from the center of the spiral outward to any given point at the center of the turbine inlet cross section.

At any given point on the tubine spiral, there is an area of the inlet and a distance from the center (A and R). These measurments give you a quotient called the A/R.

I felt the feeling to ramble....soemone will read it and maybe have fun reading it...
