and I've been told the oil and fuel consumption is an enormous. I don't know if these help with that but the muffler has been taken off, it's just straight pipes and has a turbo. It doesn't really matter to me that it's a gas guzzler but I'd like to know if theirs something wrong with it that it has to have an oil change every 3 months almost(based on what the guy I bought it from told me)

Adding a turbo will definitely increase oil consumption. Have you had it to the dyno yet? Did they include paperwork on the turbo install? I'd love to see a pic of the turbo...
