Need new Engine - RX8 - 2004

Hello, I was told by two mechanics I need a New Engine. Ready to Buy a Used one, Just lost...been looking on Ebay - but no luck...



Please help. Any Links / Leads are appreciated.



I have a 2004 RX8 ( manual transmission ) Looking for a low milage Used Engine.



I live in Miami. Hopefully a local one would be best.



Also, what am i supposed to do with my current engine ? Do I bring it somewhere ? can i sell parts ? Do I let the mechanic keep it ?



Thank you !
