Al primary turbos (with the exception of VF33) are interchangable same compressor inducer and exducer size.
All secondary turbos are interchangable (the VF14 will have its own wastegate)
Great upgrade with the VF26 and VF27 turbos.(these turbos run the 8 blade performance turbine wheels)
The VF31 and VF32 both BB turbos with same size comp and turbine wheels.The A/Rs of 11 and 18 respectively.
Power Enterprise swapped the turbine housing on the VF31 to a A/R 16 from a VF13 and generated the PE1016F.
The VF32 = PE1018F
