hello everyone, I am new to the site and new to the car. just purchased it earlier this week with a blown motor. its a 3s 2.3 n/a engine.

So my first question is will a 2006 3s engine fit this 2005. I found one for not so cheap, so I don't want to make a mistake by buying it and it not working for my swap. the guy from the salvage that is selling it to me says that it won't fit, but so far what I have searched there is really nothing different.
