FE3 or even better the Kia licensed version from the 1st gen sportage (already longitudinal) would be great for your car!  There was a guy who took an bored out a Sportage FE3 and put in an F2T crank to make it a 2.3L.  He then turbo'd it for about 400hp and dropped it in a Miata.  That would work nicely in a RWD P5!
