Nice looking turbo and will spool well, but the turbine wheel is a horrible piece for a performance turbo. 12 blade design is going to cause some serious back pressure problems. Plus the turbine is only about mid 60% efficiency.
We have some customers that have used that unit on 300-400ci builds and have not been happy with the logs on backpressure. Keep in mind the GT42 turbine wheel flows about the same and does this at 74% efficiency.

Why not just put it in the middle and run the downpipe like PSJ has on his setup? That minimizes the hacking necesitated to fit the turbo / downpipe and would still allow you to maintain your AC.
