i'm not sure what you mean with the diameter data you posted above, the major/minor diameters should just be 2 numbers, the minor side should just be measured from any two opposite fins, or even just housing inducer inside diameter.

i was looking for the minor or small side diameter of the impeller and the major diameter, with the compressor housing off you can measure the diameter of the wheel at its base (the biggest slice) and to get the minor diameter you can just measure the inducer at its base, where the impeller is.

same with the exhaust turbine if you could measure them, with these measurements i can identify the turbo.

the compressor wheels that i have a rcord of are listed below, the basic diameter measurements on the compressor wheel should fit one of these wheels, there's a list for turbine wheels as well, but if you can post those measurements i'll find the turbine wheel measurements as well:

1. TRIMS: 3262MAA/MGB/MNA, major: 80.7mm, minor: 49.1mm, hub heights: 40.7mm or 44mm
2. TRIM: 2970N, major: 72.4mm, minor: 50.6mm
3. TRIM: 2966NV, major: 72.3mm, minor: 48.1mm
4. TRIM: 3070G, major: 75.8mm, minor: 52.5mm
5. TRIM: 3064G, major: 75.9mm, minor: 48.3mm
6. TRIM: 2963U, major: 72.3mm, minor: 43.6mm
7. TRIM: 2960U, major: 72.3mm, minor: 45.6mm
8. TRIM: 3060G, major: 75.9mm, minor: 45.6mm
