This is the Traxxas 2.5R Racing Engine with IPS                 
                  (Integrated Pilot Shaft) and Pull-Start.                     
         For use in all Traxxas vehicles that use the TRX 2.5 engine.          
                                                                               
 ** This engine is a .15 engine. The 2.5 refers to a measurement of Cubic **   
    Centimeter displacement compared to Cubic Inch displacement (.15).         
                 60% More Power that the TRX Pro .15 engine!                   
  Loaded with advanced features such and the free-flowing rear exhaust, the    
  unique composite slide carb, and innovative porting only found on the most   
                          exotic racing engines.                               
                                                                               
FEATURES: Slide carburetor provides less restrictive, straight through airflow 
            for more power and better throttle response.                       
          PowerTune head is machined from aluminum which promotes even heat    
           distrubution for stable engine temperatures and rock-solid tuning   
          New sleeve for improved engine efficiency and better power.          
          Molded head protector prevents damage to the head and secures the    
            glow plug wire.                                                    
          Ultra-low restriction air filter provides superior air flow and      
            filtration for more power and a long engine life.                  
          Offset wrist pin further reduces piston slide loading for more       
            even cylinder wear and longer engine life.
