I'm building a SpecRX-7 for the Central division and have a few questions about what can/can't be removed. Specifically, in the engine compartment I've removed the air conditioning compressor, expansion valve, and hoses. I also removed the cruise control module and cable. What about any of the other emissions-related canisters, hoses, etc? Can anything else be removed to clean up the engine compartment? The rules (SoPac) mention disabling the shutter valve...how? I'd greatly appreciate some help on this from someone.
