The S1 is by all means a very fast little car. But it can become much faster by borrowing the turbo from its bigger brother, the VW Golf Mk 7R.

Turbo comparison
This is what an IS38 turbo looks like compared to the stock IS20. The size difference is more than enough to provide a 60-80hp gain and it is a bolt-on solution. No modifications necessary when replacing the turbo.
