I know the 1.8t has the k03 or the k04, but the k04 is barely any bigger and delivers almost the same PSI. The bigger question is: what other more powerful turbochargers are compatible with the 1.8t without any other mods? Which are the cheapest?
Can anyone show me websites where I can get a new bigger more powerful turbo?
Also, what's the most PSI the stock 1.8t engine can handle?
