if money weren't an issue, could a head be sent to DPR or JWT and have the port & polish work done, and then put that head on a SR20DET?

uhh, ya why wouldn't you be able to?

when it comes to forced induction, i'm basically a bonehead. that's why i call myself the N/A guru. :D
has anyone done this yet?

nothing, nada...nobody has done a P & P and put a little turbine under the hood?
