S54 Swap
 

Has anyone attempted or looked into an S54 swap for the twins? I loved the S54 in my old E46 M3 and I love my BRZ. This would be the best of both worlds. Would it even fit?

Where there's a will there's a way.

Know any engine builders named Will?

2JZs and B58s fit so I don't see why it wouldn't. Likely $20k+ all said and done.

You totally could, and its a great engine... but gosh they're getting hard to find replacements of, have a bunch of maintenance needs, and expensive. Similar power to one can be obtained a lot of less-expensive ways unless you just want to be different. It's a cool idea and probably can be done, just not sure how practical it actually is?
