Yes the Mpi kit is available both in Canada and the US, It has been since Dec 2010.
Mpi has built this 180 hp turbo kit to provide a alternative for the Nytro consumer. What I like about the MPI turbo kit is that includes a under tunnel exhaust with a muffler and no welding required, Hard pipe for charge tubes, A billet intake manifold sealing with o-rings and a huge billet blow off valve, Installation is so easy that it does not even require you to even remove the bottom panels because the oil is taken from and returned to the head, The fit,finish,performance and ease of installation IMO is second to none. Also VERY good instructions with pictures every step of the way. There are alot of pictures and feedback on this kit at:
