Matching numbers

[Shake-xrturbo]

Hey guys I was wondering how do I tell if the block and head in my BA XR6 Turbo are the original ones for my car that came from factory e.g numbers matching

Similar Question, just bought a fg xr6t ute, was wondering what turbo it has on it as I bought it from a dealer but has mods/tune already, says m12 garret on it, does the stock fg turbo have that on it? what is the stock fg turbo? a gt3576? 
Cheers Sam

well, your question is completely different, but yes both the front-covers of stock turbochargers for BA-FG have M12 stamped on them (left 61mm turbo, right 53mm FG XR6T turbo):

Further to your identification, the 61mm turbo has a 6+6 blade arrangement and the 53mm turbo has a 7 blade arrangement. Both are "cast" wheels so if it has billet steel machining markings on it, you know it's not a stock setup.

You can tell if the engine block matches your VIN number, but the head isn't matched up with an identifier, as far as I know.

 

 

 

for both of you.

Awesome Thanks mate, what turbo is on the fg f6 310s? gt3582? does that also say m12 on ?

yes, the FG F6 has the same turbo as the BA-BF and it is equivalent to a GT3582R and yes it has M12 stamped on the stock front-housing.
