I'm totally new! I'm from Italy and I'm desperate.
I'm searching for information about a turbocharger ihi vf38 (or vf44 or vf45).
I can't understand what's the difference between vf38 and vf44 and vf45.
Compressor wheel ind/exd are different? Turbine wheel ind/exd?
Journal bearing? Or ball bearing? Someone say that they're ball bearing, but on ebay and others I see that they're journal bearing..
Thank you very much!
Some ebay link to understand:
In the second link they say that vf 44 replace VF38 VF45 and VF47. So vf47 is very similar to vf38, vf44 and vf45 too?
Sorry for my bad English, but I'm really going mad about all this VF twin scroll turbochargers.
