Default Turbo Size Question
I put a Garrett turbo on my car awhile back and when I bought It the guy told me It was an 88.All I know about It Is It has a .96 A/R compressor houseing and a 1.08 A/R exhaust houseing.Exhaust outlet Is 5",the compressor inlet Is 5" and the compressor outlet Is 3 1/2 inch.How can I figure out the size of this.

Thanks
Brad

Are you sure the compressor isn't a .69 A/R?

If so, it's probably a GT47.

Use an inside mic to measure the ID of the compressor wheel inlet at the wheel. This is the inducer size and will be 88mm if it's an 88.
