ok so i bought a 1991 180sx with a sr20det engine with 95xxx km and along the way i have bought aa new bov, air filter, s14 clutch, complete tune up and new fuel filter. My issue is whenever speed shift at high rpm...
im not sure its a myth or just a stupid urban legend...some people say that BOV is bad for your evo (evo7 especially)...will give problem especially in idling mode...
