Manley Platinum Series Forged Piston Set - Toyota 2JZ (87.00mm Bore +1.0mm Comp. 10.0:1) PN: 609115C-6

Product Description ⚠️ Technical Build Warning (Read Before Purchasing) This specific Manley piston kit features a specialized Flat-Top design with a minimal -2.50cc volume. Unlike standard aftermarket 2JZ pistons that lower your compression for low-octane pump gas, this set creates a high-compression environment. Your exact compression ratio depends strictly on your cylinder head choice: 2JZ-GTE (Turbo Head / 45cc Chamber): Yields a high-compression 10.0:1 CR. Ideal for high-response E85, methanol, or naturally aspirated setups looking for sharp throttle response. 2JZ-GE (Non-Turbo Head / 37.7cc Chamber): Yields an ultra-high compression approx. 11.4:1 CR. Primarily reserved for dedicated all-motor (NA) builds or specialized fuel classes. Critical Engineering Dimensions Bore Diameter: 87.00mm (+1.00mm Oversize) Piston Type: Flat Top (with valve pockets) Piston Net Volume: -2.50cc Compression Distance (CH): 1.338" Piston Weight: 360 grams (per piston) Designed For Stroke: 86.00mm (Standard/Stock Stroke) Designed For Rod Length: 142mm / 5.590" (Standard/Stock Length) Wrist Pin Size: 22mm x 2.250" (0.150" Wall Thickness) Premium Materials & Manufacturing Features 2618 Aircraft-Grade Forging: High-silicon alloy built to withstand extreme cylinder temperatures and aggressive ignition timing without fracturing. Factory Moly-Coated Skirts: Features an advanced anti-friction skirt coating straight from Manley Performance to protect walls during cold start-ups and decrease friction. One-Fixturing Machining: Unique manufacturing process ensuring the ring grooves are perfectly square to the piston skirt for optimal ring seal and maximum horsepower retention. Valve Pocket Depth: Built to safely accommodate up to +1mm oversized aftermarket valves. What’s Included In The Box? (6) Manley Platinum Series 87.00mm Forged Pistons (6) Total Seal Premium Steel Top Ring Sets (6) Premium Chrome Moly Wrist Pins (12) Round Wire Locks Installation Notes Machine Shop Requirement: Because this requires an 87.00mm bore, your engine block must be bored and honed +1.00mm over factory size. Always supply these physical pistons to your machine shop so they can measure exact skirt-to-wall clearances before machining. Recommended Skirt-to-Wall Clearance: 0.0035" (measured exactly 1.100" from the bottom of the oil ring groove). Always verify clearances with your machine shop prior to final assembly.
