JE FSR Forged Pistons Nissan Silvia 180SX 200SX S13 89-90 CA18DET 83.5mm +0.5mm 0 cc 8.5:1

This is the newer FSR (Forged Side Relief) skirt style. JE is slowly transitioning all of their applications over to this superior design. The FSR forging allows unmatched strength while shedding unnecessary weight through machining. In short, they are light, and strong, and they are the future of pistons.

JE has lead the Piston market since the very beginning. All of the big boys making noise in the industry right now use JE because of their superior design and strength. This is a top of the line piston that one would use to build the ultimate street engine or a reliable race engine. All pistons come balanced within one gram, include pin lock grooves and wrist pins at no additional charge.
