Hey guys so I recently went from sr to rb25 but I have a frew questions before I finish my install.

The factory rb tb has a coolant hose going through it and its making fitment issues. Can I just cap both ends off at the tb and loop it under the manifold? Or can I just use my stock sr tb and tps? Thanks in advance. Also if anyone has a website that lists compatability for the rb25 like plugs, belts, oil filters etc that I can pick up from a local parts store that would be great. Thanks in advance and here is a little picture of it so far.

I've never seen a rb25 tb with coolant lines. I believe the one you have is a q45 tb. Yes, just cap off the coolant lines. There is a thread that has all of the other stuff listed. I think its called rb replacement parts or something like that.

You can just leave the coolant lines on the throttle body off, its a straight shot so it wont hurt anything. On my KA i even pulled the steel sleeves the hose goes on, since they are just pressed into the throttle body. Then just run a new line that follows the same path just longer so it excludes the throttle body of course.

At the top of the forum there's a huge thread of interchangeable parts.
