MC Engines LO206 Performance Engine with New Style Coil National Level Build

Built LO206 Engine Package with New Style Coil

What you get with a MC Engines blueprinted LO206 package

• Hand measured and selected cam profile matched to your class and weight
• Hand picked internal components with only the best parts used in your engine
• Carburetor fully disassembled built from optimal parts and tuned for your class
• Flow matched air path from carb to intake and from intake to head
• Precision valve work for stable sealing and repeatable performance
• Light decking of the cylinder head for proper sealing improved chamber volume and better CCS
• Ignition timing optimized by carefully squeezing timing from the areas the rules allow

• Exhaust system engine mount clutch chain guard and catch can installation done the correct way to prevent any negative performance effects
• Personalized build based on your MC Engines build sheet information

This is our complete LO206 race ready package built with the same careful process used for national level customers. Every engine begins with a full cam profile measurement as soon as it reaches our bench. We hand select cam profiles based on your class such as adult slide junior cadet or kid kart along with your racing weight and home track.

To tailor the build for you we require an MC Engines Build Sheet. It is available in the downloads section of our site and is the official form for engine personalization. Please download it from the MC Engines build sheet download page. This form is requested at checkout and if you do not submit it the system will automatically email you reminders. We cannot begin your engine until your completed build sheet is received.

Throughout the build we hand pick individual internal parts to create the most consistent engine possible. Certain components are screened so tightly that roughly seventy percent are set aside. Only the best flowing and most consistent parts are used. This attention to detail improves reliability and repeatability on race day.

Each engine receives a fully tuned carb system. The carb is disassembled and we choose the most optimal pieces to build it with for your class and weight. Once assembled we tune it for clean throttle response and stable power. We then match the flow from carb to intake and intake to head to create one smooth predictable path. All procedures stay within the LO206 rule structure so everything remains legal.

If you add a clutch to your order we blueprint it before installation. Engagement is set for a clean consistent curve that helps you accelerate out of the corner the same way every lap.

Ignition timing is another area where we gain performance legally. We squeeze timing from the allowed areas to reach an optimal number for your class and weight. This step helps the engine pick up stronger in the mid range and stay more consistent deep into a long heat cycle.

Valves are precision ground to maintain sealing through multiple race days. During cylinder head preparation we lightly deck the head for clean sealing and to prevent gasket leaks. This process also improves chamber volume and CCS giving the engine more consistent power while staying inside the rules.

We dyno test every engine to ensure strong power and to verify that all systems are working correctly. Box stock engines generally gain three to four tenths from our process. Additional gains come from optimized cam selection and better matched flow between carb head and block using our flow bench.

For final assembly all surfaces and clearances are prepared for long term dependability. When customers order accessories we install the exhaust system engine mount clutch catch can and chain guard the correct way. Proper installation is critical because poor installation of these parts can cause performance loss. We ensure the angle alignment and clearances are all correct so you get full potential from your package.

The steps listed above are the public part of our process. We also apply several internal fine adjustments developed through extensive dyno work and track testing. These additional steps help create engines that are fast consistent and dependable for an entire season.
