About

Zenoah G320RC 31.8cc 4-Bolt Engine - Complete with Clutch

Brand new in 2014 for the Zenoah G320RC 31.8cc 4-Bolt Engine. This 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 (G230/240/260/270/290RC).
This Zenoah G320RC engine has a 38mm bore, and 28mm stroke, for 31.8cc in its stock form. A revolutionary new cylinder design with closed deck transfer ports (two piece), with removable covers headline the biggest changes from the original RC engines.
The release of this Zenoah G320RC engine is the biggest news to hit the R/C engine world in years! With our testing of this engine we have found it to be the new standard for performance power and reliability.

Very important:



This engine's outer clutch housing is available in 2 versions. When ordering, select the clutch housing option you need from the drop-down menu.

BB125C - This is the factory version of the motor - comes exactly as manufactured by the Zenoah factory, with no modifications. Fits HPI Baja 5B/5T/5SC, Kraken Vekta.5, Helicopter, etc. This is the version that will work properly for most applications.
This is also the version that would work with the Losi 5IVE-T 2.0 and DBXL 2.0 models when paired with the Losi LOS252093 clutch housing. The 2.0 Losi models do not require a CY fan cover or clutch mounting plate.

BB125H - This is the factory version of the motor, with Go-Ped carburetor linkage parts. Go-Ped customers should choose this version of the engine. The factory clutch is installed and included. This engine is compatible with CLUTCH DRIVEN SCOOTERS. It will not fit a direct spindle drive scooter. You must use the ADA clutch drive for models like the Go-Ped Sport and Bigfoot models.

BB125D - This version of the engine has a modified "shorty" clutch housing - For R/C cars that were originally designed specifically for CY engines, which have less total engine width. Fits Losi 5IVE-T 1.0 models, TLR 5IVE-B, Losi Desert Buggy XL (DBXL) 1.0, and Redcat. A CY fan cover must also be used for this engine to fit a Losi 5ive, TLR 5IVE-B, Losi DBXL or Redcat. This is the stock fan cover from your Losi 5IVE, Losi DBXL or Redcat. We also have these fan covers available for purchase separately (see item EG411), also at the bottom of this page in the "related items".

MOST Losi clutch bell set ups also require you to use the CY Clutch plate (see item GT244) and clutch plate bolt (GT249) as the Zenoah mounting plate pushes the clutch shoes too far out. This includes stock Losi/TLR clutch bells.

Note: Aftermarket Billet aluminum clutch housings are available for the HPI Baja 5B/5T/5SC, Goped, Kraken Vekta (see part number GT396) and Losi 5ive/DBXL & Redcat. (see part number SM106SV, SM110). If you plan on using one of these for a Losi 5ive or Losi DBXL, purchase the BB125C and save yourself $5, as you won't be using the stock clutch housing anyway.

Here is a YouTube video that helps explain the clutch options:




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


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. DDM offers a +2mm stroker crank available now. 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.

Details

Fits most all the same applications as the regular Zenoah R/C Engines:
HPI Baja 5B/5T/5SC, Losi 5IVE-T, TLR 5IVE-B, Kraken VEKTA, Losi Desert Buggy XL (DBXL)/MTXL, Redcat, Go-Ped Scooters (clutch driven versions only), Helicopters, and more!

For Go-Ped use - This engine will bolt on and work on existing 54mm clutch models. Will work on spindle drive models only if ADA clutch is used (part GT201).

This is a complete engine - including carburetor, air filter, clutch, and muffler. In many applications including in most RC cars you will remove the factory Zenoah exhaust muffler and air filter to use the exhaust and air filter that came with your model. The factory Zenoah air filters are not made for extremely dirty or dusty environments.

If you have a G320RC and you are looking to increase your power output DDM suggest the following options:

Upgraded transfer port covers. These can be used with the factory Zenoah cylinder as well as any ported or modified cylinders. Bartolone Racing and Turtle Racing/OBR offer some that can be seen here: Bartolone Covers and TR/OBR Covers

With the stock crankshaft you can increase peak RPM and peak horse power with a ported cylinder set from ESP: Race Ported ESP G320RC Top End Kit

DDM also offers a race ported cylinder set from Bartolone Racing that can be viewed here: Bartolone Race Ported 32cc Top End Kit

You can modify the engine with a long stroke crankshaft which increases total displacement. With a long stroke crankshaft you will increase total torque, generally RPM will decrease a small amount. ESP offers a non-ported 34cc kit: ESP Modified 34cc upgrade kit

For the most power available with the stock crankcase you can get an ESP Race Ported AND modified 34cc kit. This gets the benefits of increase RPM from race porting and increased torque from the long stroke crankshaft: ESP Race Ported AND Modified 34cc upgrade kit

A modified and race ported 34cc top end kit is also available from Bartolone Racing: Bartolone Race Ported and Modified 34cc Top End Kit

The most dramatic way to add power will be using a tuned exhaust pipe. The exhaust port is the same as original RC style engines. This means any existing exhaust on your Zenoah or CY RC style engine will fit. You can use Dominator, Bartolone, and Victory RC pipes on these engines with great results.

Horsepower ratings vary based on what information you pull from. This engine is significantly more powerful than the Zenoah G290RC engine. By adding a tuned pipe and additional power upgrades like ported cylinder kits, modified transfer port covers or long stroke crankshafts you can make the G320RC a formidable powerhouse. Check the "Details" tab for more information on what suggestions DDM has for power upgrades.
