New to this scene and looking for a quick answer about something that is a little vague in the AARA rulebook for Belleville/Pevely. I know I can contact them, but I just wanted to throw it out to see if someone might be able to answer it faster. The rule in question is this one: "Any car or truck with a single or dual cam 4 cylinder engine may be run. It must be completely stock as manufactured, engine, drivetrain, suspension, and fuel system, except as noted below. No turbo's, No rear or mid engine vehicles." The car in question is a 1990 Ford Probe GT(2.2L Turbo). This same engine was also available in this year without the turbo. Does the rule say the car is ineligable, or that the turbo must be removed. In other words should it read "Any car with ... 4 cylinder engine may run, except those MFG'd with turbo's, rear, or mid engines." OR "Must be stock....except for turbo's, front, or mid enigne." Would removing the turbo make it legal? Or is it just ineligable because it was originally equipped on this particular unit? Thanks for the help guys.
