differences?

 

You are asking to compare 2 of the same thing? That is like comparing apples to apples. You need to be more specific and list the trims of the turbo to make a comparison.

 

i think he is wondering the difference between the names maybe? lol

 

your asking up to compare a t3/t4 turbo with another t3/t4 turbo
there are millions opf different t3/t4 turbos all with different trims.
a t3 t4 normally means the exhaust is t3 and compressor is t4. a t3t04e is a type of t3/t4 turbo also with many different trims and power ratings. for example at 60-1 is a t3 to4s with makes more power than the to4e's

 

ok now i learn something
