my ct9 died so i just did a hybrid conversion few months ago. just want to share some reference pics of ct9 and ct12.
compressor housing
ct12 has a bigger and deeper canals compared to ct9
Exhaust housing
ct9 has a bigger wastegate port compared to ct12.
ct9-square flange
ct12-triangular flange
compressor wheel
as you can see the ct12 has a bigger compressor wheel. but the design of the wheels are almost the same.
exhaust wheel
again ct12 is bigger than the ct9
actuator
the ct9 actuator has 2 ports for hi and lo
the ct12 has only 1 port but its actuator is stiffer than ct9s
assembled and installed
