Hello, New to the site so hi to everybody. I purchased a 99 a3 1.8t, agu engine. Its all standard apart from the forge 007 i fitted to it. Now i knew it wouldnt be long before i wanted more horses. I can perform the conversion myself i just need to know a few things. Ive been weighing up getting a k03s or a k04 I know the k04 can handle a bit more power than the k03s but im looking for approx 225 hp (stock s3 power) but potential for more if needed. Anyway, What im asking is, If i go out and buy a k04-001 turbo and bolt it onto my a3 what would the power be (approx?) and could i run it / drive it right away?? What else would i then need to get the 225hp, what kind of map? Injectors? Also will it bolt on with the standard exhaust. ? Hope you understand my words. Thanks in advance. Nick.
