ok so i e-mailed these people for the Ko3 that can be turned into a ko4 for 500 bucks here is wut they said. Hello....Thank you for your interest. Yes, we can upgrade the k03 turbo
to
K04 spec's. This includes the larger K04 compressor wheel and the heavy
duty K04 bearing system. The compressor wheel that we use in these
upgrades is larger thatn the K04-0015's compressor wheel. Let us know
if
you have any other questions. Thank you, i still dont know about them it sound to good to be true.
