possibly a non stock turbo??

[87ttypeV8]

i have alwasy thought my turbo on my GN has been stock...

today i took it off since my head gasket blew and the turbo says....
Garett
A/R .60
M10

and on the inside of the silver side it says .60

is this stock or not?

just wondering
thanks!

and btw... i have 009 injectors on my car right now and just wondering if they are correct for whatever type of turbo this is!!

thanks in advance

STOCKER INLET BELL HAS A BUNG FOR THE VALVE COVER BREATHER. ALSO THE STOCK COMPRESSOR WHEEL HAS 7 EQUAL LENGTH BLADES.

mine has the 7 equal length blades inside... i thought that another turbo had the same center section and a different housing??

maybe not?

if you got the 7 blades its stock. check out gnttype.org turbo guide here:

you'll see what im talking about with the blades. any other upgraded turbo will have differnt wheels. most all the turbos up to like the 66 use the small shaft center housing, maybe thats what ur referring to.
