Hello I would like to help you.
The only source that I have found here in the USA is here www.car-part.com
the Verona was imported here in the USA from 2004 to 2006 and has the 2.5 I6 engine there are a lot of these motors available here. The prices are listed on that site.
I hope this helps you
Thanks. Would you have a source in Japan?
no sorry but most of those places would Ship.
