Jonno,
We do sell a complete turbo kit using the T3/T4 turbo that we sell at
www.koracing.net that includes everything necessary and the turbo for $2190. If you have your own turbo, I can most likely use it in the SB turbo kit, but due to modifications I make to the turbos myself, I would need for you to send me the turbo to incorporate into the kit, and the cost would be $2190 less the cost of the turbo.
