The closest thing I can think of is the Works turbo kit which uses the stock manifold and a smaller/responsive turbo - if you take a look at those dynos (the intercooled version) it's pretty close to being in-line with the current supercharger offerings. Even then, it's apples to oranges - they're too different. My advice to anyone shopping across both, is to try to get a little seat time in each. Positive displacement superchargers, centrifugal superchargers, and various turbo kits will all feel different, often it's more of a matter of preference instead of overall efficiency when deciding on aftermarket FI kits for our cars.

The problem is that there is not much of a choice for us unfortunate to live in a RHD country when it comes to turbo
