CP Piston & Ring Set for Toyota 1JZGTE/2JZGTE-Bore (86.5mm)-Size (+0.5mm) - SC7472

CP-Carrillo Forged Piston Set — Toyota 2JZ 86.5mm, 10.0:1 (SC7472)

A +0.5mm set at 10.0:1 in the 2JZ, and CP's shelf catalog is the reason to buy it — their standard offering already includes features most manufacturers reserve for a custom order.

Dual forced pin oilers feed double the oil to the wrist pin. Accumulator grooves come standard: a pocket behind the top ring where combustion gases collect, which reduces ring flutter and improves seal. Better seal means more downward force on the piston, which means more power. Pin fitting — the final hone on the wrist pin bore — is done at no extra cost.

Dedicated forgings, fully CNC machined, and balanced to within ±1 gram so every piston in the set is the same. Custom skirt cam and barrel designs, and full radiused domes with deep valve reliefs that clear oversized valves and high-lift cams. Suitable for turbo, supercharger, and nitrous applications.

Specs: 86.5mm bore (+0.5mm over), 33.99mm compression height, -4.5cc, 22mm (.866") wrist pin at 2.250" long. Sized for 86mm stroke with a 142mm rod. Ring set is CPN-3406. Made in USA.

Fitment: Toyota 2JZ-GTE and 2JZ-GE, 24-valve. Also fits 1JZ-GTE applications, where the same piston lands at 9.0:1.

Verify your chamber volume — 10.0:1 assumes 45cc heads on the 2JZ. Head work moves the number.

Block work required — +0.5mm means boring and honing to size.

Includes 6 pistons, high-performance ring set, wrist pins, and pin lock grooves. Wrist pins and pin fitting included at no charge.
