Stock HP VS Twin Turbo HP : result
 

Always look good with turbo kit :eek:

I called them a long time ago about the kit. It is really not a kit, it is a custom job that they made look like a kit for the magizine. They said they can do a twin turbo kit but the car would have to be in the shop for about month or so and it would cost mucho gusto. Hell, anyone can build a kit for enough money.

It doesn't look that hard to fabricate, ofcorse it would be totally custom, but anybody with the time and money and patience to build a twin or single conversion would have the ****, SC400! You could also do a large singe and just route the exhaust into one and then to the turbine housing.
