HKS Metal Head Gasket t=0.5mm b=89.5mm Toyota GT86 & Subaru BRZ

Opposed Bead Stopper Type Metal Gasket for the FA20 engine of 86/BRZ provides higher bore sealing durability than a stock gasket.
2 types of the gasket are available. One is t0.5 increased compression ratio type for an NA engine (ε12.6←12.5, supercharger installable, Endurable approximately 300ps)and another type is t0.7 high engine output type for a supercharged engine (ε12.4←ε12.5, Endurable approximately 600ps with supercharger)

<POINT-1> Maintain a high seal with high pressure!

Both types are endurable against high engine output. Stopper structure of the bore seal is separated type so it prevents leakage even under high gas-pressure at high engine output.


<POINT-2> Compression Ratio for an NA engine is increased!

The t0.5 type (supercharger installable) for an NA engine was designed to increase the compression ratio compared to a stock gasket as well as seal durability. Also, it is thinner than a stock. It is the best to use for one make race with an NA engine. Compression ratio of the gasket for an NA engine is ε12.6. Its thickness is t0.5. (Stock compression ratio is ε12.5 and thickness is t0.6.)


<POINT-3> Contact surface pressure is improved!

Special coating was applied on the head side and cylinder side to improve sealing performance when tightening the bolts.


<POINT-4> Bore seal pressure was confirmed in figures. (See the diagram below.)
