Hi there,
I have bought over $4000 worthed of goodies in the e-bay for my upgrade in the last month. Actualy that is how I found and join SAU via a power seller from e-bay. You have to choose careful the item and the person you are dealing with. There are good deals..and bad deals and always will be a better deal.
As for a turbo, after blowing 3 standard I did not settle for anything less than a GARRETT T04E. I saw a guy in the ebay listed a T28 as a T04E (internal wastegate). My turbo is a second hand one..but imported by the guy who fitted so if something goes wrong..he will hear from me.
Good luck to you all.
