I recently got a Civic Si 00' and i want to build it up all motor. It has intake that came with it. Next im thinking about getting ITR cams, toda cam gears, valve retainers, and a pnp/valve job. After that im thinking about stroking it to 1.8l and getting high compression pistons, my question is the gains worth stroking it, or should i just get High compression pistons and leave it 1.6l. Any advice would be great, thx.
