Need help! New to the forum

I recently got a 2007 TL. 6 weeks into getting it it rained pretty bad here in Houston and it flooded. I drove thru what I thought was a regular puddle, but ended up being pretty deep and my engine sucked up water. So now I have low compression on some of my pistons and completely lost all compression on piston #1. What year engines will fit? It's a base model 3.2


TIA!
