What is your budget and what is your hp goal? I know the Vortex charger has the ability to make a good amount of hp but I dont know what Neuspeed did to it....I believe they use the Vortex charger????

Have you thought about a motor swap? If you go with a 2.0 16v motor swap you look to have about 150hp with mild work. Mild Work= intake cam chip(motronic) and exhaust. Wrecked 2.0l Passats are becoming more common in junk yards.
