I am looking for some inexpensive performance upgrades for the 2.0 non turbo. Any ideas would be appreciated. There don't seem to be very many upgrades for the 2.0 that i've seen.
try neuspeed.com. If your jetta is 93-99, I know they have an ECU upgrade chip that will give you a 10 or 11 hp increase, among other things. I had one in my 2.0L and I could really tell the difference.
A header makes a big dif. on the 2.0's. I bought one for my jetta on ebay for around $125. Make it breathe better with whatever you can. Get a k&n and do exhaust.
