Title says it all. What's the difference between the t4ob and t4oe turbo series? I'm vaguely aware that the t4ob is older, but that's about it...

Dimensions, similarities, flow? pros/cons..

anyone?

The T04e is around 30% bigger for a given trim.

Having said that, I've got a T04b 50 trim cold side here and it's significantly larger than a T3. Will be good for 400hp I reckon.
