What is the LS/VTEC motor?
The LS/VTEC motor consists of a B18A or B18B block and a B16A head, B18C head, or a Type-R head. Basically, it is still an LS motor, but with performance cams and a port & polished head. Also, the B16A intake manifold flows better than the B18A intake manifold so airflow into the motor is greatly increased. Basically in a CRX a B18A powered CRX (1.8L DOHC non-VETC motor) has a lot of low-end power to accelerate down the mile. Off the line, the B18A CRX will easily beat the B16A CRX (assuming both are stock or have the same bolt-ons). However, on the long stretch, such as on the freeway, the DOHC VTEC really shines and pulls the car hard at high speeds for more horsepower. Now imagine getting the beat of both worlds the LS/VETC motor, which utilizes the B18A, block (for all the same torque) and the B16A head (for all the top end horsepower). That is basically what the LS/VETC motor is. In addition, others who have built a LS/VETC motor have prepped it to full race status and have alread
