Hey ephatch, I'm brand new to the forum and I'm happy to be here I own an 2005 EP3 si, but I'm currently just a broke high school kid so I haven't done much other than an AEM cold air intake and an exhaust that was put on by the previous owner. I'm looking to engine swap my car because the thrust bearings went out and the engine has 240k on it, it lasted a long time but it's hit the end. I've been looking into putting a K24a2 into it, but I was just curious as to what the pros and cons of the other blocks/heads were, I'm looking for a good base to turbo once I'm in college. Thanks!
