The ProTek R/C Samurai S03 3-Port .21 Competition Nitro Engine is the perfect weapon for 1/8 scale buggy applications, where extended run-time is critical. The Samurai S03 delivers a lethal blow with its high mileage 22D "High Efficiency" carburetor and long stroke configuration. Combine this with a 3-Port sleeve, turbo head button, 9 fin cooling head and rear ceramic bearing, and the S03 becomes a formidable opponent with its smooth power band, performance and proven reliability.

The Samurai S03 has been meticulously designed and crafted in Japan by a leading maker of model engines and delivers a versatile package like no other – excellent power delivery, predictable, crisp throttle-response and consistent carburetor settings are all traits every racer needs to stand atop the podium. So remember, when you head out to the battle field, it is better to fight with a Samurai than against one.

ProTek RC Samurai S03 3-Port .21 Competition Buggy Engine w/22D Carburetor
I ordered this engine about 5min after it was loaded to the site, recieved it on a Monday and raced it that Tuesday. EBIS break-in performed by me, Flashpoint 30% fuel, OS 2100 pope set, Kyosho MP10 buggy. The engine is clearly more powerful than the Ty2/2101 engine, but not nearly as peaky and insane as the Spec 2 that has the same bore/stroke. Smooth but powerful mid range and great torque out of corners. More drivable than Spec2 but similar feeling over all power due to a more linear powerband. Will update as I get more fuel through it. So far so good!
