SirpriZ, I'm not sure what you're saying. Are you claiming that this turbo kit (La-Z-Link) takes a Garrett GT2560R turbo and swaps the compressor wheel to a GTX2860 compressor wheel? That is incorrect.
This turbo uses billet wheels from Turbos Direct. They're not Garrett GTX2860 compressor wheels mounted on to a GT2560 turbo.
