I am brand new to the forum and to Honda civics. My story is I have always been into muscle cars f-bodys to be specific, I love working on cars in general. I recently finished a project that I had been building since 2006, a 2000 pontiac trans am ws6 with a built and boosted 408. Now that I have completed that I want to try out something new and was thinking about getting a 1991 civic hatch si. What motor swaps can you do? And how much hp potentiol does one of these have? I am planning on boosting it with a very smooth suspension so I could use it as a track car as well as a daily driver to drive to work.
