So I bought a s14 with a rb25det series one, the head gasket blew and it probably demge more because it got extremly over heated, the fan didnt turn on.. So i replaced the head gasket but it wouldn't fire up... So I bought a whole new MOTOR , RB25det NEO 6, swapped it in, turns on but the gas throttle is not reponsive and it lags very much, What could be the problem? do i need to swap anything else ecu, cam, coil pack?
