Modifying more top racing engines!

The EB Modified versions of the 12TZ™, 18TZ™ and 18TM proved so successful, that O.S. has applied the same advanced technology to two more popular engines! By using precision equipment and machining, EB Mods has fully balanced the 30VG and 21VZ-B V-Spec — increasing their power and performance even more!
