FEATURES

Crankcase

The new crankshaft gives the engine a better balancing. This will reduce the vibration produced by the rotating and the alternating masses.

Cooling head

This a 'Lighter&Lower evolution 3' type of cooling head. It is drilled and milled out to reduce the mass of the coolinghead which sits high up in the car and thereby lowering the Center of Gravity of the engine/car. 

Backplate

The rear cover presents a round shape to optimize the filling and reducing the dead spaces. the steel plate is to reduce friction and to expand the lifespan of the conrod..

4 Ports ABC Piston Sleeve

The sleeve has 4 transfer ports , the best compromise to make a linear power supply with minimal fuel consumption combination possible.

Crankshaft TURBO

As this engine comes as "Factory Tuned" we have modified the crankshaft to futher improve the power output and driveability.


Gasket:
The inner shape of the gasket has a new shape, and with that more material. Together with a change in material these gaskets are more resistant to high temperatures.
