Well that's my DD and not supposed to be the project, so I put as little time and effort into it as I can. LOL! So... The answer to the question about what engine did I put back in is "The same one that came out." I only pulled it because it needed work done on multiple sides of the engine and at that point I thought it was just simpler to pull the whole thing and do everything with the engine out.
Belt side needed new timing belt. Bottom side needed oil pan gasket. Rear side needed new engine mount (taught kid how to drive stick). Transmission side needed new main seal and clutch, etc. So since I needed to work on left, right, rear, and bottom, I just pulled the whole thing out to do the work.
I did do one "bonus" item... I pulled the subframe and put in an Integra steering gear for a faster steering ratio. But that car is not the project.
