wheel is a 50 trim m8 so bigger than rst but smaller than 2wd cos.

exducer is the usual 60mm (common t3 size)
inducer is 42.5mm.

ex housing is as per saab etc although never seen a housing so not sure on fitment

cover is again std t3 (same as cos,rst,saab blah blah blah)

shaft is std t3 as is bearing housing,seal plate (blackplate)

saab 900 is a match on specs but again maybe not fitment (model tb0382)

Without really looking into it more cant help much m8, obviously you can find a 50trim map
