The easier swap is the TII engine from the same series of your car. I you are getting an imported j-spec be prepared to rebuild it.

For 350-450HP, the easiest engine would be an S5 TII engine. They have the heavier rear plate like the REW but bolt right in. You're going to want to rebuild and street port it, if for no other reason then the condition of the engine is unknown and the street port will make achieving those power levels easier and lag free.

Of course, remember that you will want to put the whole TII drivetrain behind that engine.
