Recently,I have been trying to find a good turbo kit for my 2011 xB. The eBay ones look way to good to be true. The only one that I have come across that looks "ok" is the FastScion kit but not sure if that is the only option.
Godspeed manifolds aren't bad, if you want to piece together a kit. You can probably save some money here and there doing it that way.
OR if you want actually quality stuff, that's designed for our cars, go with Dezod/World Industries. With most of their kits you'll get everything you need, including a baseline tune and bigger injectors.
