I want to go with 6466 but I daily this car, so I am leaning more towards 6262 or maybe even 5858. Just trying to stomp all the 5.0's here in town, and currently I am neck and neck with them haha. JMS racing is a very reputable shop here in town, btw. ready...GO!

 

6466 for the win, my buddy was running a 5858 and went up to the 6466 and said there was minimal difference in spool time, so running the bigger turbo didnt hurt at all. and looking at your build sheet it should handle the boost.

 

I would do an MHI 18k, or an FP red. Both will put you over 500hp and be a lot more fun to drive than a big laggy T3 setup..
