there are two blouch turbos that you can use on the MY11s.
th Normal turbo that requires a PW TMIC and Hotside Pipe and the Blouch Legacy GT one... which also fits the WRXs.
IF you are not interested in doing the Headers, TMIC or Intake i would go the 18G as it is very responsive and spools fast. IF you intend to go the headers, intake, exhaust, silicon inlet etc i would go for a 20G as the MY11 Engines can handle a little more power then the MY06-07s due to better knock detection and better piston design.
we are getting around 220kw-240kw@wheels with a 18G and 250-275kw@wheels with the 20G..
We have them all in stock now and our prices are now on par with USA, Plus we port the turbos where USA dont and you get a free Blouch Jumper
