The system operated at 350 kPa and used Multec II injectors that were more precise than past injectors. Up to 3,000 tons of force forges aluminum slugs into the basic piston form which creates a grain flow pattern in the structure providing excellent strength, ductility and improved heat dissipation. This alleviated the need for a separate Exhaust Gas Recirculation system, or EGR. These vehicles were designed around the I6 engine. G. One reason this installation looks so clean is because the majority of fabrication work is hidden underneath the engine. As a result, they form a uniform body with extreme strength.
