What kind of Garrett Turbo is this? (Specs inside)

[ForcedInduction]

I bought this turbo on ebay

( http://cgi.ebay.com/ebaymotors/ws/e...&rd=1&item=7918890811&ssPageName=STRK:MEWA:IT )

It says it's a T3/T04E. I popped the compressor housing off to measure the compressor wheel.

Here are the specs...
Garrett .50 A/R Compressor Housing w/ 7cm Turbine Housing.


Compressor Wheel
Overall Diameter-3.6"/92mm
Exducer-3.6"/92mm
Inducer-2.3"/59-60mm

Compressor Housing Intake
Inside Diameter 2.4"/61mm
Outside Diameter 2.75"/70mm

Compressor Housing Outlet
1.6"/70mm

I tried searching yahoo and what not for almost 2 hours. I also did the math to figure out the trim size. (60/90x100=65 trim) all the measurements I did with my digital caliper....so they are not down to the .0005" or anything. Just enought to get an idea. I decided to post here to see if someone coule help me out. Thanks in advance.

actually, to figure out the trim you need to take the squares of the measurements you took. it's a 45 trim and it's really big.
for comparison, the "50 trim" and also the "green" have measurements of: 3" and 2.123". so that turbo is pretty damn big!

I knew I forgot somthing....and that somthing was to square the sizes for math. Thanks for your help.

After hours and hours of searching online I think I covered everthing. This is what I know.

T04E .50 A/R Compressor Housing
T3 Center Section/Exhaust Wheel
7cm TD05 Turbine Housing
T61 Compressor Wheel

As for the measurements of the Compressor Wheel I am almost positive it is a T61. The only thing that throws me off is that I have 7 blades and other T61 wheels I see are 6 blades. Here is where I found the measurements.

I think this may be it. Or similar from another company.

Are there diffrent versions of the T61 Compressor wheel?
