why is this and most of you guys recomend the ats compressor housing? is one better than the other?

 

Do they move up to a ball-bearing turbo?

They spool quicker to reduce lag, that would be one reason to replace the whole turbo. Another would be because they want a bigger turbo. A bigger turbo making the same boost as a smaller turbo will be more efficient and create less heat which is safer for not only the turbo, but for the engine as well. Could be several reasons...

 

no turbo al they have a turbo housing they sell similar to the ats ported housing but its not for the say wicked wheel side of the turbo it goes on the other side???

 

Yes,
thats the exhaust side. Its probably just bigger/ported housing just like ATS. This is essentially making half the turbo bigger and more efficient. Probably brings EGTs down a bit and helps it spool quicker. It is not cheap to replace the whole thing, and they probably came to the conclusion that the whole thing doesn't need to be replaced, so if it aint broke, don't fix it!

 

sorry turbo al i was just curious why banks chooses to replace the exhaust side and ats ported housing is on the intake side that most guys recomend

 

I would think it helps keep EGTs down more than just porting the intake side...

Anyone else have any more ideas?

 

must do the same thing on eliminating the turbo surge and stall??
