Unlock the full potential of your Wildcat 240RS engine with our Stage 1 Performance Kit—engineered to increase durability, raise the rev ceiling, and deliver real-world horsepower gains.

While the 240RS is a strong out-of-the-box performer, its capabilities are capped by factory limitations like cast internal components and rev-limited ignition. Our Stage 1 kit upgrades the most critical elements to safely push performance beyond 6100 RPM and prepare your engine for future modifications.

Key Benefits:

• Increase RPM Limit: Eliminate the restrictive factory coil rev limiter.

• Boost Spark Energy & Timing: Optimize combustion and throttle response.

• Strengthen Internal Durability: Upgrade to billet-grade components for high-rpm reliability.

• Up to 20% More Power: Gain horsepower and torque with simple bolt-on upgrades.

Included in the Kit:

Tillotson 138190045 High-Output Ignition Coil

• Replaces the rev-limited stock coil

• Increases ignition energy by 2 millijoules

• Advances ignition timing by ~10%

• Commonly used in racing engines for reliable high-RPM performance
  

SK200 Rev Wheel Billet Flywheel

• Increases ignition timing up to 34° when paired with the upgraded coil

• Boosts spark energy for better throttle response and combustion

• Lightweight billet aluminum construction for reduced rotating mass
  

EC Pinnacle 8270 3.303” Billet Connecting Rod

• CNC-machined from 7075 aluminum forging for unmatched strength

• Clears cam and block without additional machining—unlike other rods

• Built to handle increased compression and high RPM reliably

Performance Gains:

With the Stage 1 upgrades installed, you can expect:

• Up to 20% more horsepower and torque over stock

• Increased engine durability under racing or high-load conditions

• A reliable foundation for future upgrades like cams, carbs, and big-valve heads

Compatibility:

• Specifically designed for the Wildcat 240RS engine

• Direct bolt-on components—minimal modification required

FAQ

Q1: What performance gains can I expect with the Stage 1 Kit?
A: The Stage 1 Performance Kit can deliver up to 20% more horsepower and torque over the stock Wildcat 240RS. This is achieved by removing the RPM limiter, increasing ignition timing, and upgrading to billet internals for higher revs and better combustion.

Q2: Will this kit remove the factory RPM limiter?
A: Yes. The Tillotson 138190045 ignition coil included in the kit removes the factory rev limiter, allowing the engine to safely exceed 6100 RPM when paired with the upgraded billet flywheel and rod.

Q3: Is any machining required to install these components?
A: No additional machining is required. The EC Pinnacle billet rod is specially designed to clear the camshaft and block without modification—unlike other aftermarket rods.

Q4: Is the kit compatible with other upgrades?
A: Absolutely. This Stage 1 Kit lays a durable foundation for future performance upgrades like performance camshafts, high-flow carburetors, and big-valve cylinder heads.

Q5: Can I install the kit myself?
A: If you’re experienced with small engine builds, this is a bolt-on-friendly kit. However, ensure you follow proper torque specs and timing procedures for best results. If you're unsure, we recommend professional installation.
