2003 MS 3.0 to 3.5

[deroach]

Hey guys, I'm new to this whole forum thing and I cant seem to find the answers I'm looking for. Long story short, I have a 2003 Montero sport with a 3.0 and I'm wanting to swap it out with a 3.5 of the same year if that's possible. Am I gonna need any extra parts or should it just fit right in?

There are a few issues that ES ran into, and has been working out over the years, like throttle body, and running lean etc.
