right.... well itr (b18c5) is a great motor buts its not the top of line. there are better and more power motors out there. dont get me wrong a itr is awesome. it really depends on what you want as far as mods go. if you want n/a that would be a great motor. if you want boost go with a lower comp. motor like ls or b20. its all about your plans and finances. which money is a big deal with alot of people.
