What all performance upgrades could I do to my ghibli?There are no bolt on upgrades. The turbos are built into the exhaust manifold which complicates things a bit. There are companies that can "upgrade" the stock turbos for higher performance. If you're seriously considering it, you may want to buy a used set from a parts car and send those out to be upgraded since it will likely take weeks or longer to do and your car won't be out of commission during that time. Then you can resell your stock ones to recoup that expense.
Thank you for the insight. I found the carbon fiber intake boxes and fabspeed has a pretty nice decat full exhaust with valves for about 7500.00. Do you have any suggestions on a chip tune?
