whatever...
Only thing I can`t figure out, is how to choose right IHI turbocharger - I do not see any additional indexes, for RHF4 or RHF3. Does it mean that RHF4 will always the same RHF4 for any vehicle? For example, Garrett GT25 series turbos has the same turbine, but different size of air compressor (GT2540, GT2554, GT2560).
