if all you can find is a na engine you can take your heads lim and blower off the blown engine and bolt em on the na engine, add a set of headers and off you go. a tune would be needed too. but will run ok as is as long as you keep it out of deep boost. if you get kr.

my top swap needed a degree of timing removed to be kr free on a stock pulley. gen 5 blower you may need to pull two degrees.
