Zenoah G320RC ENGINE 4 bolt with Clutch & Carby

Zenoah G320RC 31.8cc 4-Bolt Engine - Complete with Clutch & 1107 Carby  

Brand New Model, the Zenoah G320RC 31.8cc 4-Bolt Engine. All new design - redesigned cylinder, crankcase, crankshaft, piston, etc for an absolute explosion of power, yet still in the same size package as the original Zenoah RC engines (G230RC, G240RC, G260RC, G270RC, G290RC)

This Zenoah G320RC engine has a 38mm bore, and 28mm stroke, for 31.8cc in its stock form. Includes a revolutionary new cylinder design with closed deck transfer ports (two piece), with removable covers.

The release of this Zenoah G320RC engine is the biggest news to hit the R/C engine world in years! We have been testing this engine for the last few months, and the power output is incredible.

*This engine is not compatible with most FG Modellsport or Smartech models. The larger crankcase interferes with the input shaft into the transmission.

What is the same as the existing Zenoah R/C engines:

Pull Starter

Fan Cover

Ignition Coil


Inner Clutch Parts

Spark Plug

Carburetor Gasket

Exhaust Gasket


Air Filter

Small Oil Seal

What is different:




Piston Pin, Bearing, Washers



Crankcase Bearings

Outer Clutch Case

Engine Cover (shroud)

Crankcase Gasket

Insulator Gasket

Cylinder Gasket

Piston Pin, C-Clips, Washers, Bearing, etc

Insulator Manifold


Large Oil Seal


Displacement: 31.8cc

Bore: 38mm

Stroke: 28mm

Dry Weight: 2.3kg

HP: Approx 3.5 or more (before adding tuned exhaust). The G290RC is commonly listed at 3.5hp, but this engine puts out considerably more power than the G290RC. Adding a tuned exhaust or other modifications will further increase horsepower and torque numbers.

Overall Dimension: 164mm Length, 215mm Width, 196mm height

Fuel: Pre-mixed gasoline and 2-cycle oil, 25:1 ratio

Fits most all the same applications as the regular Zenoah R/C Engines:

HPI Baja 5B 5T 5SC,  Helicopter, and more.

**For Losi 5ive, Losi Desert Buggy XL (DBXL), and Redcat. The modified clutch housing is required . A CY fan cover must also be used for this engine to fit a Losi 5ive, Losi DBXL or Redcat. This is the stock fan cover from your Losi 5ive, Losi DBXL or Redcat. Or  will need to be purchased seperately . Some clutch bell set ups also require you to use the CY Clutch plate  and clutch plate bolt  as the Zenoah pushes the clutch shoes too far out.

The crankshaft is a different style (larger) than the original zenoah engines, so the existing +2mm stroke crankshafts on the market will NOT be compatible. But, crankshaft compatible with this engine is available .With a 2mm stroker crankshaft installed, this engine will become a Zenoah G340RC Engine (38mm bore, 30mm stroke, 34.02cc) performance beast!!!

The exhaust port spacing is the same as the original engines, so all exhausts, tuned pipes, etc will remain compatible.

The cylinder includes removable transfer port cover plates, these plates can easily be removed for easier access to the transfer ports.

Will fit :HPI Baja 5B 5T 5SC, **Losi 5ive, Losi Desert Buggy XL (DBXL), Redcat,  Predator RC KM & Rovan all Models
