Car Maker: Nissan
Car Model: Silvia (S13, S14 and S15) and The 180SX
Engine: SR20DET
Nissan SR20 turbo and non-turbo common "copper plated cylinder liner" The outer circumference of the liner is copper plated. The surface has been treated to ensure that the heat inside the cylinder is transferred to the cylinder block body. The material of the liner body is a cast iron material for cylinders containing boron. The inner diameter is made smaller than the normal bore, so normal pistons and normal bore 86mm pistons can be used. Of course, there is no problem using it with an 87mm piston. Even if the top of the cylinder block has melted, it can be used by inserting this liner. After inserting the liner, there will be no more melting problems with the block.
(Liner insertion processing set 120,000 yen (excluding tax) Work content = Liner pilot hole processing, liner insertion, block surface grinding, boring honing with dummy head. Please send us the block and front cover.)
