Manley Toyota 2JZGTE 86.0mm Bore STD Size 10.0:1 CR Flat Top Piston Set with Rings - 609100C-6

Manley Platinum Series Forged Piston Set — Toyota 2JZ-GTE 86mm, 10.0:1 (609100C-6)

A standard-bore flat top at 10.0:1 — the compression most 2JZ builders land on when the car sees pump gas and moderate boost, and the ratio that keeps a 3.0L six responsive off boost instead of feeling lazy below 4,000 rpm.

Manley's Platinum Series uses domestic 2618 alloy forgings for high-temperature strength and fatigue resistance. Offset wrist pin design keeps start-ups quiet, and moly-coated skirts reduce friction and scuff risk. The crown accommodates +1mm valve sizes, so a head that's been worked doesn't force a different piston.

Manley's single-fixturing method turns the skirt and machines the ring grooves in one operation — ring groove to skirt squareness you can't match with a two-op process, which is where ring seal and power come from. Cam and barrel skirt profiles make power while staying gentle on cylinder walls.

Specs: 86.0mm standard bore, 1.338" compression height, flat top, -2.5cc volume, 347 grams. 22mm (.866") wrist pin, 2.250" long, .150" wall.

Fitment: 93-98 Toyota Supra Turbo, 2JZ-GTE 3.0L.

Set your clearance to spec — .0035" measured 1.100" down from the bottom of the oil ring groove. 2618 grows with heat, and a tight bore is how these get scuffed on cold start.

If you're going past 800 hp on E85, consider the Extreme Duty version (609100CE-6) — same piston with 9310 alloy wrist pins.

Includes 6 pistons, Total Seal premium steel top ring sets, premium chrome moly wrist pins, and round wire locks. 9310 pin upgrade available.
