Our New Rotating Assembly Is Designed For The Predator 212 Hemi To Increase Displacement To 223cc

The Predator Hemi Has A Shorter Deck Height Than Most Other Honda-Based Clone Engines. Due To The Deck Height, It Was Difficult To Use Current Aftermarket Components With The 58mm Stroker Crank In This Block. Usually, Stroking The Engine Required Clearance Of The Rod, Cam, Crank, And Piston For Fitment. We Have Resolved These Issues With Our 58mm Stroker Kit For The Predator Hemi.

Kit Components:

Wildcat 223cc, 70mm Flat Top Piston- The Wildcat Piston Provides Clearance Between The Crank’s Counterweights and Piston Skirt. The Wildcat Piston Is Also Lighter Due To The Different Designs. The Piston Comes As A Complete Assembly With Rings, Wrist Pins, And Circlips.

EC Pinnacle Forged Rod- The Forged Rod Is Shorter Than Stock To Set The Flat Top Piston At Zero Deck Height (Some Variance May Be Expected with Mass-Produced Blocks.) Unlike Many Other Rods, The Dipper Doesn’t Interfere With The Cam Core, Making Installation Easier.

Wildcat 58mm Crankshaft- the Crankshaft Is the Same Used EC236R And The Wildcat 223 Engine. The Crankshaft Should Only Require Clearance Matching With The Camshaft, Depending On The Lobe Profile And The Compression Release. The Crankshaft Also Using The Honda / Clone Tapered Flywheel; The Hemi Flywheels Will Not Work. We Recommend Using Our SK200 Rev Wheel.

The Purpose Of This Kit Is To Offer More Displacement To Predator 212 Hemi For Classes That Are Limited To Predator Brand Engines.

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.
