T4 coldside. Great T3 upgrade... full Garrett T3/T4.
 

Great t3 upgrade. Convert your typical Garrett t3 to a full oem t3/t4. Wheel is larger than the 60/63, but same size housing. Push more CFM. I'll work on getting wheel measurements, just need to find a mic to borrow. Should be about 72mm, as thats what it was advertised when I purchased it.

It is used, but barely. Looks almost new, blades are perfect and such.

Asking 125+ shipping.

Located Chicago, IL (western burbs)

that is def a to4B wheel of some sort.

I'll try to even check the part number, I believe its still on the backside of the wheel. I can't ID it much further with a Mic though.
