JE Pistons Toyota 1FZ-FE 100.5mm Bore +.50 Oversize 8.5:1 CR -11.7cc Inv Dome Piston Kit - Set of 6

If you're rebuilding the engine in your Toyota 1FZ-FE, this set of six forged pistons from JE Pistons is a solid choice for high-performance applications. These pistons are specifically made for the 1FZ-FE engine and are oversized by 0.50mm, with a bore size of 100.5mm. They feature an inverted dome design that results in a compression ratio of 8.5:1, which is ideal for boosted or high-performance naturally aspirated builds where you need a bit more room for boost pressure or want to run aggressive timing.

JE Pistons has been making performance pistons for over 75 years, and these are forged in the USA from 2618 aluminum. This material offers high tensile strength, crucial for handling the demands of a performance engine. They incorporate JE's proprietary Forged Side Relief (FSR) design, which helps reduce friction and skirt wear, saving weight and improving efficiency. Some applications may also include an accumulator groove to improve ring seal and reduce ring flutter, along with a skirt coating to further cut down on friction and noise.

This kit comes complete with everything you need to get your pistons installed: high-quality wrist pins, locks, and JE's Pro Seal premium piston rings. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
