In the past 5 years I have learned a lot from various forums and use that information to modify my car with the intention to have a better road car with good sport performance and occasional 1/4 mile race. Here is a graphic story of my Cars evolution from stock K03 to whatever it evolved into, English is not my language so I will not put much detail in the descriptions but if someone have a question fell free to ask and I will try to share whatever experience I gained.

Could you post the details about this setup? I will go for the AWD conversion very soon and I was thinking of using the USP Auxiliary pump I have with the OEM one but I think your setup is much better.
