So I'd like to know what's the different between a t3t4e and t3t4b. Does anyone have measurements on the compressor cover.

besides the letter? mpressor housing and the wheel of course the "E" are normally bigger and sport a 70 A/R housing and a 56 trim wheeel the "B" normally is a 50-60 A/R housing and ranges from 60-70 trim wheel it all depends on which one you get t3/t4 are hybrids but the standard are that as followed they both are capable of flowing about the same but spool charateristics and flow are different , when i say capable i mean given the right applications they can make the same power,
