Details on what you bought and what you know about the car like , did you check the oil level before purchase ? Did you check the oil level after the problem ? A small amount of oil can look like a lot . Has any work been done to the car , upgrades/ maintenance ? It's a little late now but you should have checked out the car mechanically before you drove it aggressive . Use the search function to find "the 6-p's" by ash . This is a starting point with any new Z purchase . Before you go throwing new turbos on that engine you really need to know how sound the engine is or you're just throwing money away . Give us more info and we"ll try to steer you and don't take your Z to just any mechanic . Don't even take it to a good Chevy/ford mechanic . You need to locate a good Z mechanic near you and build a relationship between him and your car . Start saving money this isn't a civic . Good luck and keep us updated .
