First of all if you would buy a RS2000, buy a MK5
It's true that tuning a N/A engine costs a lot of money, but if it's a daily drive the RS2k is a very reliable and good driveable everyday car, they are VERY underrated cars. If you want more info look on: www.RS2000-16v.com

oh, btw, you can swap do the 2.3 conversion on low budget...
