6275 - 7.2hp Full Mod Zenoah 29.5cc 4 Bolt LOSI Engine

Full Mod - Our top of the line engines. 

Same specs as our normal full mods but tuned for more torque. This engine was specifically desinged for the Losi 5ive-T. We have installed a CY clutch and fan cover for a direct bolt up. The 29.5cc engine does not have quite as much torque as a 30.5cc but is higher reving. Ideal for larger tracks. 

The 29.5cc is a great all around performing engine and can be used for most applications. The big bore 36mm top end with a 1mm stuffed crank is a great balance of torque and rpms. 

This isn't your run of the mill quick and dirty garage port job. The staff at OBR has over 20 years combined experience tuning engines. We know how to get the job done right the first time with out breaking the bank. 

To start we machine the combustion chamber for a proper squish clearance and compression ratio. We learned a long time ago that stacking and/or using thicker  cylinder gaskets does not make power. From there the cylinder and piston are aggresively modified but not to the point where reliability and ease of use is lost. Reliability and ease of use is always our first objective when we tune an engine. Every port in the cylinder has been professionaly modified and the piston has been lightened and relieved. 

 
This engine fits: Losi 5ive-T
