First off Hello and welcome. Next. With the idea that your car is running good stock. Great upgrades that require no major mods are as follows: Exhaust system - Some say go 3in some say 2.5 inch. I say 2.5 when doing slight modification and running smaller turbo's. 3in is for higher set-up requiring more flow and running bigger turbo's. IC piping - A good 2.25in or 2.5in piping here would be great. BOV - You need one if you like having your turbo working in the long run. These cars if you do not know do not come with one stock. So all that boost comes back threw the turbo when you let off the gas. It stalls the turbo, creates lag and unneeded wear which will shorten its life. Air Filter - You can drill holes or cut a hole into your box. Just remember that the system in place pulls air from outside. By cutting or drill holes you allow the extreme heat these motors and turbos produce to be used in your intake system. We all know cooler air proves better results MBC - Getting a good manual boost controller would be good to slightly turn up the boost as well. I would exceed 12psi on the stock turbo if you would like to see a long life out of it. IC - Upgrade the intercooler. A little bit more work involved: Stress relieve your stock exhaust manifold. Then get it resurfaced as it will probably tweak a little from the webbing being cut. Also you can port this. From here it can go hundreds of ways. You can delete things such as AC, EGR system, Oil separator an such. It all depends on the end result your looking for and if you don't care to have certain things. You can always drop weight by taking out your back seats, passenger seat and spare tire. Or start applying heavy mods like going MPI with a bigger turbo. It is really up to you and how deep your pocket is. Hope this helps -Garret
