K04 conversion

Hi guys, wants to get my TT a little more horsepower, but I’m not sure how to do it.Could you just install a chip, but that’s kind of too dangerous for me, because so many people say that he does motor(indirect)caputt!What do you think of the turbo conversion?Have a 180 front, and think that there’s a 03 in it and wanted to ask if someone here knows someone who has also built a K04, what it costs etc.? Have you seen one for 570€-good? he search used and only found that there is and also which have made a conversion, but no details. So don’t freak out ;-)! Help me dear ma*g*!! Thank you
