A 2001 is difficult to power-up. Depending on your budget I would do a high flow intake and exaust. If it is an LPT you can always put in a bigger turbo with a higher flow. If it is an LPT look for a turbo beginning TD014. The next numbers are the different performances e.g. 18T 19T. After that get a custom tune flashed into your computer. If it is an LPT, a 19T with these mods can increase the power to almost 300hp.
