This is the LRP ZR.21X Spec 2 7+1 Port Off-Road Competition Buggy Engine. The LRP ZR.21X Spec.2 has been been refined and upgraded. The Spec.2 has the potential to be the next must have 1/8 Off-Road engine. At first glance it's obvious that the changes include more than just the small details. For significantly improved heat dissipation, the upper blue cooling fins have been turned upwards, combined with cooling fins on the head button. A genius and revolutionary idea. The XTEC thermal protected WorksTeam 14SV-2 carburetor has been developed to provide smoother performance. Instead of standard aluminum, the carburettor is made from rigid Ergal grade aluminum alloy. The result is a level of smoothness that generally can only be found in much bigger engines.
