Hey guys I recently bought a b17a1 n installed it on my 93 DA. Everything works perfectly but the VTEC it does not engage wat could b the problem ? Any help
did you wire in the pressure switch and vtec solenoid? was the engine at operating temp? if so i would verify pressure switch is closing/sufficient oil pressure see pin outs below
if all of that checks out look into the solenoid wiring, also check for clogged oil screen on solenoid
PS
might have better luck posting in the appropriate section :rockon:
