Description
New 1.0mm thickness gasket is released as an additional item to the existing 0.5mm & 0.7mm thick bore stopper type metal head gaskets for the FA20 engine of 86 & BRZ. This gasket provides higher bore sealing durability than stock. Use with HKS Capacity Upgrade Kit provides optimum performance of the supercharger kit.
Maintain high seal with high power!
All three types are durable against high engine output. Stopper structure of the bore seal is designed to be separated type so it prevents leakage even under high gas-pressure at high engine output.
Compression Ratio for an NA engine is increased!
The t0.5 type (SC installable) for an NA engine was designed to increase the compression ratio compared to stock gasket as well as increase seal durability. As it is thinner than stock, It is the best to use for one make race with an NA engine.
600ps D1 spec (t=0.7mm) is produced for a supercharged engine!
The t0.7 type (SC installable) utilizes a stopper taller than the t0.5 type to provide higher bore seal durability. It is designed to withstand 600ps engine power. Compression ratio reduction at the stock displacement is only small with t0.7 so high heat efficiency can be maintained.
600ps (t=1.0mm) is produced for HKS Capacity Upgrade Kit!
The t1.0 type (SC installable) is designed to use with Capacity Upgrade and utilizes a stopper taller than the t0.7 type to provide higher bore seal durability. Use the t1.0 type to adjust the compression ratio of Capacity Upgrade Kit; setting range can be widened.
Contact surface pressure is improved!
Special coating was applied on the head and cylinder side to improve sealing performance when tightening the bolts.
