Hi, how to read compressor maps?
The T04B 62-1 is better then T04E 50 trim?
All T04E serie is better then T04B?

"Better" is a subjective term.
The 62-1 is bigger than the T04E-50.


In general, yes.

Ok i simplify my question.
I have 2 choice: first choice put only 62-1 trim compressor wheel from T04B serie in my T04e 50 trim .70a/r compressor housing (rebore ).

Or:Second choice change compressor housing and wheel ( with same a/r )
All have the same performance?

 

-The 62-1 compressor wheel is much bigger than any T04E wheel.

-The '60' trim T04E is not even as big as the 60-1 wheel.

 

So a T04B 60-1 will make more power then any T04E?

What about T04S 60-1 vs. T04B 60-1?

 

Is a T04B 60-1 also called the "60-1 HiFi"? Whereas the T04S 60-1 is the "normal" 60-1?

 

Yes, the T04B 60-1 will make more power than the largest T04E, the "60" trim.
T04E's are a newer more efficient design, but the T04B 60-1 flows more. T04B housing inlet is larger and the compressor wheel is bigger.

T04S is not a Garrett designation.

AFAIK the (HKS) T04S is just a T04B 60-1 with a specific housing A/R no?

No. The HIFI housing has a smaller inlet and outlet, that is all.
