i dont have a jeta yet and i dont have any experience in VW. i was wondering wich engines in the 04-06 jettas is going to be the cheapest and easiest to build up and have the most parts. ive noticed the 1.8t and the 2.0t do but the onl engine if seen in the 06 jettas is the 2.5 5 cylinder and i havent really been able to find many parts out there for it.
