check out http://www.total-boost.com/?id=15563. they have good prices on jdm engines and are really knowledgeable. ur best thing to do is swap in a h22. the v6 from earlier than 2003 puts out 200hp stock so does the h22. the h22 can be modied so much easier than the v6 plus it has a 5speed manual unlike the auto of the v6. it would cost to much money to swap in a 03 v6 if it is even possible.
