wow, do it yourself, if the extent of subaru know how for this guy is a turbo upgrade he is at the same level as me. Dont give this guy a dime a turbo upgrade is nothing like turbo charging a RS. Take it to a real shop, your going to end up paying for it in the end when this guy dosent tighten your up-pipe bolts right and you have a up-pipe leak, or installs the injectors wrong and you have a unnoticed fuel leak and your engine leans out. dont let this guy f-up your car, do it right you will be much happier in the end.
