For sure you can keep the intake and exhaust. I don't have headers on my car because I knew I was eventually putting a turbo on and didn't want to spend a lot of money on something I knew wouldn't be converted over. Since both engines are a 2.2 the headers might work. I don't know too much about the fitment but I wouldn't see why they wouldn't. I have AEM pulleys and my guy said I think they would just need difft belts. Hope that helps.
