Is there a guide to tell me what size and type of turbo I have?

?? How could you possibly know that??

Just a guess mostly. But my 49 has the same casting #'s on it.

With those #'s it's obviously a Garrett, & a 44 or 60 I think has a larger A/R ratio. So, my guess is it's a TA49.

Stock turbo's also have those casting #'s. I just went through this not to long ago.
