1st) you pay for what you get as i said before... i dont know what kind of power your talking about? what bt kit did you have anyway? you can make power for cheaper but its going to break, go up in flames, throw codes, ect. anyway you look at it if you plan on up grading a VW/audi or any german car your paying out your ass.
2nd) k04 is a good upgrade if you wanna do dig runs but falls flat on its face on the highway. best turbo for a 1.8t right now is the gt2871 good spool great top end good price.
3rd) sell your vw and get a subie or something w/ some real power. for what i paid for my fmic on my gti i built a full turbo kit and now pull 5+ cars on my old gti on the highway and 15+ from a dig. for a little over 1,500. and it is a much better daily driver
