The Stage 1 Turbo Kit for the Impreza RS 2.5 and Impreza 2.2L comes with a Garrett TO4E Turbo. This is a 5 PSI system with about a 60-80 HP gain and 2 seconds faster in the quarter mile. There isn't any lifting of the engine and it will install in a weekend. This turbo charger is capable of supporting 500 hp. Price on the kit is $2995.
NOTE: This kit is the same as the Stage 2 kit, except it does not include a Intercooler. You can, however, upgrade to a Intercooler.
*All of our kits contain everything to Turbo Charge your vehicle. The only thing that the customer would have to supply is a minimum of a 2 1/2 inch exhaust system from the catalytic converter and back as the factory exhaust is much too small for Turbo applications.
