I am planning on running a Borg Warner gm3 off a 93 chevy turbo diesel truck. Now I have asked this question and picked up many different answers. I have googled around trying to find some sort of solid answer.

(I don't care about how much work it takes to make it work yada yada.) I have already fabbed it to fit on my car.

My only concern and I am hoping one of you guys or girls could give me a straight answer.

1. What is this turbos CFM rating
2. What is the inducer size
3. What is the extducer size
4. Compared to a 16g 18g and 20g Which is it closest compared to?

I have been told this turbo is a .58 trim turbo and told it was a .54 trim turbo. I have also been told it was a .60 trim turbo. The tag number on the turbo has been painted over by previous owner of the turbo so getting the numbers is going to be difficult. It has also been filed down to make it smooth looking =/

heres a pic of the turbo for an idea.
