No I won't leave it stock. I plan on getting some 403s, DC 4-2-1 header, PWJDM Whale Penis, Greddy SP2 or Ti-C exhaust, Exedy clutch+ lighter fly wheel (12lbs or a ITR 14lbs one). Sure it won't run great on stock ECU but i want my immboi. A tuned car won't do me much good if it's stolen don't you think? I will explore some options on installing some kinda of kill switch or something if I decide to go OBD1 in the future for tuning. But I will still need to swap my OBD2 ecu back in for emissions. I still need to research and decide which path is best. I'm a fan of doing something different, aka a non-VTEC build.
