So I've done a lot to my 05 1.8T and I'm excited to do even more, and take the next step by upgrading my turbo. I just bought this one: BILLET KO4-015xl K04-015XLB XS-POWER Upgraded K03 Turbo VW Passat Audi A4 1.8T, Volkswagen Turbos, XS Power Inc.
My car's engine is stock so I can't go too crazy with it, but I am beyond excited to upgrade from the baby k03. I've heard so many good things about this turbo, and my car is ready: front mount intercooler, Bosch 550cc injectors, stage 2 clutch + single mass lightweight flywheel, diverter valve, among a few other things. I'll be going from barely keeping up with newer econoboxes to full-on sleeper. I chose this turbo because I don't want lag until 5k rpm where I can't even have fun on the street. The size, and the fact that it bolts straight up convinced me. It's a huge upgrade from an eBay special without breaking the bank on a BT that I can't even use. I can't wait to get it buttoned up and update my thoughts on this little guy.
