The New! EC 236R Racing Engine Stage 3 Kit is designed to build your kart or mini bike racing engine.

We thought of what it would take to handle a 14.5ci open modified from the beginning of our development on the Tillotson Engine Program. Our new 236R is 236.15cc, or 14.41ci puts you very close to the mark and does it while being extremely budget-friendly. Our kit includes a partial short block allowing you to add your current clone or predator parts, racing carburetors, and other components. If you want to build a brand new engine, we have many add-ons to make a complete engine. Engine and Short Block do not come assembled.

72mm Tillotson Reinforced Block - This is the engine's core and allows most of the magic to happen. We designed these blocks to handle mild endurance racing engines for Tillotson's 225RS/T4 Class. We made the block thicker and more robust to reduce flex and distortion; this prevents power loss through crank flex and blow-by between the piston and cylinder. At 72mm bore, it is one of the largest bore block straight from the factory. Still, with our background in modifies, we couldn't pass the opportunity to build one of the best blocks for high horsepower applications.

Tillotson Racing Lightweight Hypereutectic Piston - This piston is advertised as a forged piston by other distributors; it is, in fact not a forged piston.
The piston is superior in performance and longevity over stock. Chinese cast pistons used in other engines and kits. The piston uses the latest technology and design utilizing a racing slipper skirt vs. a conventional barrel skirt design of other stock pistons. This piston uses an aluminum alloy with high silicon for a lower thermal expansion coefficient, allowing tighter tolerance. The low slipper skirt design allows more clearance in the rotating assembly for larger stroke crankshafts. We also made the compression height shorter by moving the pin's location and using a smaller diameter wrist pin. These improvements allowed the use of a longer rod while reducing weight in the rotating assembly.

58mm(2.283") Stroker Crankshaft - This is the first-ever 58mm stock crank for the clone market. The crankshaft is significant because it has only .017" less stroke than the billet cranks made in the aftermarket and, more importantly, at less than a quarter of the price. With our kit, you will build an entire short block for just the billet crank alone.

EC Forged Rod - EC Carburetors designed the original billet rod for Tillotson 225RS engines, using a 55mm stroker crankshaft. And we built the first billet rod to fit the Tillotson piston and a 56mm crank and are now the first to use our exclusive 58mm crankshaft. Our new EC Forged Rods are designed to allow more stroke with standard clone journal crankshafts and bigger camshafts. This rod is made in-house and is unique for our engine combination.

These components are the core of the 236R "U-Build-It" Kit. It comes with the hardware gaskets to build a complete short block minus the camshaft.

Kit Includes:
  • Tillotson72mm Reinforced Block
  • Tillotson 72mm Lightweight Hypereutectic Piston
  • EC Billet Connecting Rod
  • 58mm Stroker Crankshaft
  • Stock Sidecover
  • All hardware and gaskets included assembling the short block.
  • Push Rods are not included (Chromoly Recommended for all builds)
To build a complete engine, we have many add-ons to build many different combinations based on your budget and goals.

When You're Ready To Play With The Big Dogs But Don't want To Break The Bank. This Inclusive Kit Comes With Everything Needed To Double Horsepower And RPM Capability Of Your Motor To About 12hp.
NOTE:This Is Not A Drop In Kit And Requires Mechanical Knowledge! Some Engines May Require Additional machining and Clearance, Especially Hemi Motors.
