JDM Overhauled Engine Plan Japan

Our goal is for you and your JDM vehicle to enjoy a new life with thousands of more kilometers on the road.

• Professionally fully rebuilt engine block and head completed by our Japanese certified mechanics.
• We locate and purchase a matched donor engine for your vehicle based on the Japanese manufacture’s VIN chassis number and engine model number.
• Our expert mechanics will disassemble the engine, clean, restore or replace all worn parts necessary to restore the engine to it’s original specifications. Customization requests are received but not guaranteed.
• We do not require the original head or block to be returned. But we may be interested in purchasing the block or head after reviewing photos.
• If not in stock, allow 2 weeks after receiving payment to locate a compatible engine based on your specifications.

Important: A certified auto mechanic is recommended for installation and maintenance procedures in order for this engine to perform as designed. We are not responsible for mishaps when installations are performed by those who are novices and not certified auto mechanics.

Custom Cylinder Sleeves

Bring your old cylinder back to new condition with a new sleeve or by repairing damaged or cracked cylinders. Custom cylinder sleeves are essential components in engine maintenance and performance enhancement to help maintain consistent compression and improve heat dissipation, enhancing overall engine performance. Our sleeves are manufactured in Japan with manufacturer’s specifications.

• Durability: New custom sleeves are incredibly durable, reducing the need for frequent replacements. Custom sleeves provide a robust surface that can withstand high pressures and temperatures, crucial for small or high-performance engines.
• Repair Worn or Damaged Cylinders: Custom sleeves restore the cylinder surface, allowing for effective piston movement.
• Prevent Future Damage: They protect the engine block from wear and tear, extending the life of the engine.
• Improved Engine Longevity: By maintaining structural integrity, they help engines perform reliably over extended periods.
• Customizability: Custom sleeves can be designed to fit the unique specifications of any engine.
• Improved Performance: A well-designed custom sleeve can significantly enhance the performance of the engine by reducing friction and improving heat dissipation.

Cylinder Boring with Oversized Pistons 

Cylinder boring is necessary when installing oversized pistons to restore the cylinder’s shape, remove surface damage, and achieve the correct clearance for optimal piston performance. This process ensures that the new pistons fit properly and function efficiently within the engine. Cylinder boring is a critical step when installing oversized pistons. This process serves several essential functions:

Key Functions of Cylinder Boring

• • Restoring Cylinder Shape: Over time, engine cylinders can become out-of-round due to wear. Boring helps restore them to a perfect circle.
  • Removing Surface Damage: If the cylinder walls have scratches or scoring from issues like overheating, boring removes these damaged layers, ensuring a smooth surface for the new pistons.
  • Achieving Correct Clearance: Proper clearance between the piston and cylinder wall is vital for performance. Boring allows for precise adjustments to ensure optimal fit and function.

Boring cylinders is essential for ensuring that oversized pistons fit correctly and function efficiently. This process not only enhances engine performance but also extends the life of the engine by maintaining proper cylinder integrity. Always consult with a professional machinist to ensure the best results.
