Is there any way to look at a turbo and tell if it is a t3/t4? What are the visual differences between a t3 and a t3/t4?

 

ummmm, anything else?

 

air inlet is usually 3" or bigger with a t3/4 as compared to 2" with the straight t3s

 

Is that always true or generally true?

 

generally true, never seen a T4 compresor housing with a 2 inch inlet haha

 

Cool. Nice question. I have a garett 60/48 at home and the dude told me it was a t3/t4, which I doubted anyway.

Gonna measure the cold side. Thanks.

 

I just bought a "t3 60-1" Turns out I've got a 57 trim t3/t4 with a .60/.63 a/r.

 

Actually mine could possibly be a t3/t4 I guess. The compressor inlet from the top to bottome measures 3". If I measure from the top of the inside to the bottom of inside of the inlet it measures almost 2.5"

So I guess it is indeed then a t3/t4
