Reconsider AWD tuning. They seem to be hit or miss.
Reconsider sleeving. There is no need for that at your power goals. Sleeving is also pretty unreliable unless perfectly done.
Closed decks are nice and durable as @batmibile_engage has pointed that out.
9k for what your having done? Hell, you can get a Cosworth short block for about half that, Rallispec and Element tuning for even less. But.... I guess labor is also figured into that??
