Well, the original 2.3 in your car won't hold up to a turbo without several modifications to the engine internally (which would include a full rebuild with forged pistons) but 2.3 Turbo engines aren't too terribly hard to find in junkyards, there's at least one in three different junkyards near me and I could have all the parts to swap any of them into another car for about $500...
There is a thread in the 2.3 Tech form that details all of the necessary modifications to get a non-turbo 2.3 "turbo-ready" if that's really what you want to do though.
