View that shows posts specific to the node In my website, under every project we do, there is a project info post which summarises what the project is about as well as all the recent updates(posts) about that project. 

this is what it looks like http://i.imgur.com/yuJEnYA.jpg

I am trying to find a way i can view a 'project-info' node and add a 'view' that shows all the related 'project-posts' related to the particular project that the 'project-info' node is about.

I'm not sure where to begin.

You should begin around Views of course. Just make a taxonomy term per project, and use Views to create a page with all nodes of type "update(post)". Then in tpl.php for a texonomy field of "project info post", build a link based on taxonomy term. That's pretty much all.

Entity reference module is worth to look at, too. Using it you could relate all "update" nodes to "project info" node. Similar effect to taxonomy, has it's pros and cons of course. Read about both, and choose your poison - referencing node directly is cleaner way, but taxonomy seems to be supported better, and is in core so less contrib modules for you.

Last but not least - you could simply make the update posts a comments on project info post.
