2618 Aluminum Alloy Forged Piston

To withstand the severe demands of high compression, extreme boost, and heavy nitrous usage while maintaining reliability, these pistons are constructed from 2618 aluminum alloy, known for its superior tensile strength. These pistons are fully customized to your specific bore and compression ratio requirements, with the forging process initiated upon order. Each set includes wrist pins, pin keepers, and piston rings. Rzcrewgarage pistons feature dedicated forgings, are balanced to within +/- 1 gram, and come with free wrist pins and pin fitting. They also include accumulator grooves, dual forced pin oilers, pick lock grooves, and are fully CNC machined. Optional upgrades are available for extreme boost or high RPM usage, including up-rated pins and custom valve pocket designs to accommodate larger valves. Short skirt pistons can also be specified. For applications not listed in the catalog, custom quotes are available, though design changes and modifications may incur additional costs. This part is specifically designed to fit the Toyota 1ZZ-FE engine, identified by its 1800cc displacement, DOHC, 16v configuration, and NA (Naturally Aspirated) I4 designation.
