Ive posted on this forum before about VW vs. Audi but I think the deciding factor between an A4 and a GTI comes down the the K04. I understand the audi takes a K04-15 and the GTI takes the K04-05. First off what is the difference? Im assuming size. Ive seen most a GTIs with a K04-05 and the other typical mods (exhaust, chip, intake, dv, FMIC) dyno about 216 Hp. What is the typical dyno for an A4 with the same mods? does the k05-15 do more for an audi then a k04-05 does for a VW? please let me know. You all are helping me out so much.

The K04-15 has a 1 cm larger compressor wheel. just like the K04-25has a 1cm bigger compressor wheel that the K04-15

 

Thanks I was unclear on that. Sorry for asking 25 questions in one post too

 

Then whats the difference between the KO4-15 and the KO4-K16 hybrid

 

its not really a "K04" the K16 wheel is to big to fit in anything under a K14. thats the housing i use. you can port ou the K04 housing but it gets to thin and will detiriorate when heated. Serioulsy it will burn hole in it self

you "cant" cram a 1-series turbine into a 0-series housing
