Wildcat 223 Stage 4: A New Benchmark in Budget Performance
This blog revisits the Road to Horsepower journey for the Wildcat 223 engine, introducing the long-anticipated Stage 4 kit—a high-performing, cost-conscious upgrade designed to outpace Stage 3 results without the complexity of advanced valve train builds. Featuring the CNC-ported WC946-3 cylinder head, a newly developed .268 Reaper camshaft, and the high-flow PWK24 flat slide carburetor, the kit delivers a substantial power increase: 18.01 hp at 7700 RPM and 13.9 ft-lbs of torque at 6300 RPM—surpassing Stage 3 by 2.5 hp and offering a broader powerband.
The blog also explores why the Wildcat 223 remains a top choice over the Predator 224 Hemi and explains how EC’s Stage 4 setup rivals more expensive builds in power, while retaining stock-style components for easier assembly and affordability. Engine comparisons, dyno results, and tuning insights round out this deep dive into building a competitive, user-friendly engine for the 223/224 class.

In the world of performance camshaft selection is often a critical choice in how your engine performs. Small engine racing, unlike the automotive world, there are limited choices in cam builders and cam catalogs. Around the time we had the concept of what would become the Tillotson 225RS we started piecing together what components we needed to achieve a strong power band for a relatively low rpm engine ideally for mini bike engines.

EC Tech Review: The new Tillotson Racing Blocks designed by EC Carburetors
We have been the primary Tillotson importer and distributor for kart racing for over 35 years. Not only are we master blueprinters that can get the most from a Tillotson carburetor that dominate the limited and open races across the country, but we have also designed many different base models for Tillotson in that time. Tillotson trusts our knowledge and expertise. That's why they came to us to help them develop their engine programs.
