so i have a garrett turbo... seems no one knows what it is. Talked to Garrett and they tell me all their turbos have a hand scribed number on the cold inlet side... can't find anything... any suggestions how i can figure out what i actually have?

heres what i know:

4 bolt exhaust flange
an oil fitting

says a/r .60 M24 L B (sideways) Garrett "G-80?" on the cold side

not sure what i would need to measure to determine size

not sure what to look for to determine if its good or bad (looks new)

any help appreciated thanks

 

Post a couple pics, and measure the end of the wheels that you can see, or pull both housings, and measure both the big, and small diameters of both wheels.

 

best as i can tell, measured at the solid circular base surface of the impeller
cold side= 74.88mm wide
hot side= 63.47mm wide

attached some pics

It looks to be a t3/to4e hybrid. With the measurements given it could be a few different models/trims. The small end diameters will narrow it down.

 

thanks, measuring as far away from the center plate between the hot and cold side at the edges of the impellers on 2 opposite vanes:

hot side: 55.81mm
cold side: 56.35mm

 

The numbers don't match exactly, but sometimes it's tough to get an accurate measurement. I'm going to say its a t3/t04e, 57 trim compressor, and stage 3 turbine.... pretty common turbo.

 

thanks, garrett fumbled the support on an ID for this, appreciate your help.

so if i wanted to turbo a 4.6 mod motor, auto trans, any suggestions?

not sure single or twin setup?

wondered if i could use 2 of these? and have a set of turbos

 

2 on a 4.6 would be a decent fit. They're older tech, but still a good turbo.... most of the Ebay t3t4's are copied from them yet.
