The Bullseye compressor wheel is 90 MM inducer 100 MM exducer.
Where as the Turbonetics compressor is 88 MM inducer 90 MM exducer according to Douglas. Need to double check that.
I need to ask about the turbine trim & size.
I am pretty sure the turbine wheels are different from eachother.
The Bullseye turbo is a T6 size turbo, it pretty big in size.
