yeah IMO Im with HS-Pokey get the GSR swap, its better for boost, cheaper for the swap and if u slap a turbo then ur good, besides the Type R motor isnt really recommended for boosting cause of the cams, but people do it, but IMO i wouldnt. just get th GSR swap, and run the stock head and cams and build the motor bottom end and u'll be fine. B18c all the way
