Jesus. that would make an URRS6 (?)
Out of curiosity, why swap? Other than the turbo lag, it's so much easier and cheaper to get 700+ HP out of an AAN than a BCY. There are some crazy Norwegians on S2forum doing 700+ Hp on stock longblocks with just turbos and fueling. The rods go if you have a fast spooling turbo, but they are throwing Holset 35's on there and making some crazy numbers.
I do sort of miss my Urs6, but it was just too rough, and I spent too much money making it mechanically sound, and knew I would have $30-35k in the car by the time I was happy. And I could probably sell it for $9k. That's why I decided to just buy something I didn't have to mod to make me happy.
