Need Help To ID A Turbo? ASAP

I have a Turbonetics turbo with part # T-36644 stamped on the back of the housing. Can anyone tell me what size Turbo this is and if its a Dual Ball Bearing or not? i tried to call Turbonetics directly but, they are closed for a few days.

Thanks

If it only has 2 passages in the center (for just oil) its just a journal bearing. If I has 4 passages (for oil and water) it is dual ball bearing.
I was told the dull ball bearings do not have water passages anymore and its optional?????

I have not seen any DBB turbo with out waterlines, not even small T3 turbos. It is possible that turbonetics offers a DBB center without water lines. You best bet is to call turbonetics.
I tried to call them but, somehow their offices are closed from June 8th to 12th.

That part number may not even be relevant as it is not difficult to change the bearing cartridge. If it doesn't have water passages I would be good money that it is journal bearing setup. They get just as hot as a bigger turbo.

At First i was told it was a dual ball bearing which i found out it was BS and now they are saying its single bearing but, most likely its a journal bearing and was jacked an extra $700.00 but, i'm gonna a call it in on Monday and see what kinda turbo they sold me.

here is the picture i have for now.
