I have been reading about this part of the engin. Every one seems to say that this part is highly restrictive and making it flow better would make the car go faster. Any one out there ever think of having this part ported and polished? i am considering it but i would like to know if any one had it done with their K03?<p>also what if you are to smoothened out all the rough spots on the K03, as in porting and polishing every thing out inside the turbo.<p>Thanks for all your help.
