Our vast experiences from Drag Racing, Drifting, Rally and circuit events like Time Attack and the Endurance Race, as well as many other national and international motor sports activities, has given us invaluable knowledge in producing quality “racing engines”.

The different race conditions and applications require different engine specifications and tolerances. Today, together with a team of experienced engineers and sophisticated equipment and facilities, we are able to research and better produce motor sports engines for race applications. These specifications are based on the different requirements that our customers need, to achieve engine power and reliability. For the best performance and reliability, we recommend the use of a brand new engine block. The reason for this is that used engine blocks may have micro level metallic strain due to wear and tear and will result in lower level performance of your car.

Treatment and Assembly
1. Cleaning of Metal Components
The cylinder head and block is first disassembled and all parts are then cleaned thoroughly. Long hours of De-burring and Chamfering of all parts are then done carefully to increase assembly precision later on in the process. This eliminates the probability of problems arising from potential foreign metal particles.

2. Assembly Process
The engine parts are assembled in a temperature controlled room where dirt and impurities are minimized. The parts are then fitted and torque to precise specifications. The tools and equipment used for assembly are constantly maintained and carefully calibrated so as to achieve the best quality results.

1.Adjusting the Squish Area
To achieve the most efficient power, all the fuel inside the combustion chamber must be burnt completely in a compact area in the center, known as the squish area. The squish area is very thin and is surrounded by relatively cooler surfaces causing the air fuel mixture to result in incomplete combustion. On top of this, the ignited flame is unable to reach this thin area to cause ignition. Thus the squish area is removed and adjusted to reduce “knocking” and increase efficiency.

2. Setting of Valve Seat
During combustion, it is crucial that the air fuel mixture is sealed completely inside the cylinder to increase compression and power. The valve seats are then cleaned and set to fit the valves precisely.

3.Valve Lapping
This involves cleaning the valves to ensure improved sealing during combustion.

4.Valve Polishing
The area of the valve in contact with the valve seat is polished and then set to the valve seat. It is then further examined to ensure proper fitment.

5.Cylinder Head Surface Polish
For the head gasket to achieve optimal sealing between the cylinder head and the engine block, the cylinder head surface must be polished and made as smooth as possible to remove uneven surface irregularities.

6.Port Polishing
The uneven surface of the intake and exhaust ports results in resistance in airflow. The ports are thus polished smooth to allow efficient airflow.

7.Tappet Shim Clearance Adjustment
The tappet shim clearance is measured and set to the optimum based on the difference in camshaft profiles.

1.Engine Block Surface Polish
Similar to the cylinder head surface polish, this process smoothens the engine block surface where the head gasket is in contact.

2. Dummy Head Boring & Honing
When the cylinder head is bolted onto the block, the metallic parts flex and deforms. To compensate for this deformation, during boring of the cylinder, we attach a dummy cylinder head to assimilate the actual conditions.

3. Piston Ring Clearance
The piston ring clearances are measured to check if they are of optimal value during assembly.

4. Bearings Measurement
The main bearing and con-rod bearings are fitted and the clearances are measured to check if they are of optimal value. This is important as it will determine the durability of the engine due to the wear and tear on the crankshaft.
