6339 - Full Mod FAT BOY 46cc / 47cc Reed Case Engine - RC Losi 5ive-T

Fits Losi 5ive-T 1.0 and Rovan/30 Defree North trucks that are a clone of the 1.0. If you're unsure reach out to us before ordering and send pictures or a link to the truck you have. 

DOES NOT FIT: 5ive-T 2.0, 5ive-B, DBXL, MTXL, HPI, Redcat or MCD.

These engines are now available with the option to add an OBR pipe to make it a complete package.

Complete fully modified/ported 46/47cc engine for Losi 5ive-T 1.0 use. Does not fit Losi 5ive-T 2.0 or any other 1/5 scale car. Engine comes complete with clutch, HDA-223 carb and v-stack. You have the option of adding a mounting kit, exhaust and pinion to make it a complete package like our full mod that will have everything needed to install. For those that already have our full mod 46/47cc the engine can be purchased by itself. Pipe, gearing, mounting etc is exactly the same for the full mod and reed version. Mounting kit and pipes are required to mount and run this engine. 34cc and smaller exhaust pipes will not fit as this engine has a larger exhaust port.  Intake tract, reed valve and transfer bowls were in-house flow tested and dyno tested to produce as much power as possible. You can expect to see a lot more torque and mid range power then a piston port 46/47cc without a loss in rpm's. We've used high quality carbon fiber reed petals for more power and longer life then fiberglass petals.

Porting/machining:

intake port filled and 2 boost ports added

piston lightened/reshaped w/dual windows to match boost ports

all ports resurfaced

transfer port bridge knife edged

exhaust duration advanced

exhaust port widened and flowed
