I have a question about internals (pistons) regarding street prepared cars. Little background, Since I have a sol (2seats) I can not be in STS or Street Mod instead I have to be in DSP and Streed mod 2. I relized that a swap would put me against supercharged porsches, a 500 hp V8 focus, and alot of other insanely fast cars. Since I have suspension already I am thinking about just moding my car to the limit of DSP. Now here is my question, acording to 14.10.o "Cylinders may be rebored to .0472 in. over standard bore and the appropriate standard oversize piston may be substituted. Cast or forged, non-stock pistons of the same dimensions and configuration as original equipment pistons may be used. Additionally the replacement pistons must be of the same weight or greater as the original equipment pistons" and the definition of standard to the scca... "12.4 Standard Part An item of standard or optional equipment that could have been ordered with the car, installed on the factory production line, and delivered through a dealer in the United States. Dealer-installed options or deletions, except as required by factory directives, no matter how common or what their origin, are not included in this definition. This definition does not allow the updating or backdating of parts." The civic GX (a natural gas powered car offered only as fleet veicles on 6th and 7th gen civics) pistons fit in my engine and would give me 12.5 compression. Now would this violate this?
