ats turbine housing sizes ?

[Black dawg]

does anybody know the size of the turbine housing on the factory turbo vs. the upgrade housing? Also need to know the wheel trim. Looking to upgrade a factory turbo setup, and thinking about going to a bigger housing than comes with the upgrade. thanks

There is no difference on the compressor side. the exhaust outlet side is the difference. The aftermarket one is 3" with a slip-fit downpipe that some love to hate and the factory has the V-band clamp that the housing necks down to 2.5".
