COMETIC MLS (Multi-Layer Steel) Head Gaskets provide maximum sealing performance for today's high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flouroelastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements

For the first time ever, 2618-alloy pistons can be installed with piston-to-wall clearances near that of an OEM piston!

Many Turbochargers are built around a bearing and oil pressure profile much lower than is seen by modern & hi-performance, engines and feeding these turbochargers the appropriate amount of oil pressure hase always been a challenge. Traditional methods to limit oil pressure have been with a restrictor, aimed at reducing pressure – However this also reduces flow.

Turbosmart’s OPR T40 is a true regulator in that target oil pressure oil 40psi can be achieved without compromising oil flow. This takes the guess work out of restrictor, or feed and drain hose selection and ensure the oil going to the turbocharger, never exceeds the manufacturers tolerances – This will provide you rock solid oil supply pressure, within the manufactures tolerances.
