I've got this stock integra type r which I've raced against several modified integras and to my luck I've found out that I'm doing better 3/4 mile times. It's still complete with stock exhaust system including cathalyser and seems to be a stock ecu. Other integras include full exhaust system including 4 in one and no cathalyser, electronic ignition system and modified ecu. How can I find out if cams and ecu are still stock when consumption is still very economical compared to modified ones? And if they're still stock does anyone has any explanation for my integra being faster?
