Does these measures apply for the 170 PD as well ?
Can it be made into a hybrid with 56mm intake ?

GT1749VC and GTB1756VK exhaust housings are interchangeable. Even tough the turbine wheels are different size the housings and CHRAs fit both way around. But if you chose VK you will need to change it to vacuum actuator.

Audi 204-233hp versions use KKK BV50. GTB2260VK is used in 240hp version.

A real shame there is no compressor map available for most (all?) of them...

GTB2056v for Alfa 2.4 JTDm (210 Hp)

Compressor (6 main blades) inducer/exducer: 39.6mm / 56mm
Turbine (9 blades) exducer/inducer: 43mm / 47mm

Compressor A/R: 0.56
Turbine A/R: 0.7

Looks like quite a small compressor inducer & turbine inducer compared to other GTB2056's.
