JE Pistons Nissan FJ20 90 Bore +.50 Oversize 9.5:1 CR -3.2cc Dome (Set of 4 Pistons)

JE Pistons has been a leader in forged racing pistons for over 75 years, and they've applied that experience to their wide range of pistons for import engines. This set is specifically made for the Nissan FJ20 engine. These aren't just generic pistons; they're engineered and forged right here in the USA using 2618 aluminum, which gives them the high tensile strength needed for demanding performance applications. This means they're built to handle the stress of high-output engines.

What sets these pistons apart is their design. They feature JE's proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by using a reduced skirt width. This design also saves weight by using a shorter wrist pin. Depending on the specific application, you might also find an accumulator groove, which helps reduce pressure from combustion gases to improve ring seal and prevent fluttering. Some applications also include a skirt coating that reduces friction and wear on the piston skirts and cylinder walls, which can also help lower operating noise. This set includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings, so you have most of what you need to get them installed.

This particular set is for a 90mm bore, which is 0.50mm oversize from the stock bore. It's designed to achieve a 9.5:1 compression ratio with a -3.2cc dome volume. Remember, these pistons are made 100% in the USA, ensuring a well-built product for your engine build.
