school me on my turbo..

[NB592]

so on my 2g '97 eclipse GST when i bought it from the guy, he didnt know much about the car, or cars in general whatsoever, which doesnt help because I really dont either..

but anyways, i was told the car has the aftermarket Garrett M24 turbo, which looks right from what I can see, 4 bolt aftermarket for sure atleast
only problem is I dont know what A/R?
any way to tell with it on the car? i imagine id have to pull it off ofcourse, also can anyone give me the specs for the M24's and A/R's?
im looking to see what kind of PSI i can put to that turbo depending on the A/R size

any info is appreciated!

Around .60 A/R.. I dunno to much about those turbo's i know someone that had one back in the days, It was .60

If the M24 is cast into the compressor housing it seems to be an indication of type of metal used to cast it.
DDG- Stock Turbochargers
if you scroll down there there is info about the M__ cast into turbine housings. M24 is cast into many different garrett compressor housings, and range from tiny to huge.

It is probably a T25, which is stock, or a T28, which is upgraded. Take a picture, someone can ID it.

ok thanks for the help guys, ill post a pic asap then
the guy i got the car from said they had it put in and is supposed to be a bigger upgrade from stock, whether or not he was being honest i have not a clue, but if someone here can ID it, ill certainly get it up
