This is the New Era .21 conversion for the Traxxas Revo truck using the OFNA Picco 51221 MAX21 engine which has a claimed power rating of 2.38HP! For the Traxxas Revo owner who wants more power, this engine conversion kit is the way to get BIG POWER at a reasonable cost. With the use of this conversion kit, the Ofna Picco 51220 MAX21 engine uses your existing clutch assembly, manifold, pipe & EZ Start System.

Kit does not include engine - sold seperately. We try to stock the Ofna Picco MAX21 51221 engine. Kit includes: Custom Billet Engine Mount, Linkage Adapter Bracket, and Hardware needed for installation. Also comes with instructions.

RECOMMENDATION: When installing this kit, the spur gear can get very close to the air filter rubber elbow. We recommend also considering the purchase of the Motorsaver Traxxas Revo High Performance Air Filter RT60, because the Motorsaver rubber elbow is specially molded for extra clearance on the spur gear. You can see this RT60 filter by scrolling towards the bottom of the page.
