Traum Pistons | Toyota 2JZ Outlaw Heavy Duty Forged Piston Set — 2000+HP Rated with 22mm HD Pin

The Traum Pistons Toyota 2JZ Outlaw Heavy Duty piston set is built for the top end of 2JZ performance — the kind of engine package where boost, RPM, cylinder pressure and billet-block-level ambition all come together.

This is not a basic forged piston for a mild street build. Traum lists this piston package as suitable for 2000+HP when paired with the 22mm heavy-duty wrist pin and aluminium pin buttons, making it a serious option for high-boost 2JZ drag, roll-racing, dyno and extreme street combinations. The design includes deep valve pockets to support additional camshaft lift, which is critical when building a 2JZ with aggressive cylinder head and valvetrain requirements.

The vendor page lists options for 3.0L and 3.2L 2JZ combinations, with bore options including 86.0mm, 86.5mm and 87.0mm. Compression ratio options shown include 9:1, 10:1, 11:1 and flat-top configurations, depending on bore and engine capacity selection. Traum also notes that custom variables can be made where the listed options do not suit the build.

For Australian workshops, engine builders and racers, this is the sort of piston package that needs to be selected as part of a full engine plan. Bore size, final displacement, rod length, stroke, pin specification, head gasket thickness, combustion chamber volume, fuel, boost target and intended RPM range all need to work together. At this level, piston choice is not just about compression ratio — it is about keeping the engine alive under serious cylinder pressure.

Prime Speedworks positions the Traum 2JZ Outlaw piston set for customers building real high-output engines where component strength, machining accuracy and package compatibility matter.

Technical specifications

Application / fitment notes

This piston set is intended for serious Toyota 2JZ high-performance engine builds, including both 3.0L and 3.2L combinations. The vendor page lists bore and compression combinations including:

Before ordering, confirm:

• Final bore size after machining
• 3.0L vs 3.2L displacement
• Crank stroke
• Rod length
• Wrist pin requirement
• Target compression ratio
• Cylinder head chamber volume
• Head gasket thickness
• Valve size and camshaft lift
• Piston-to-valve clearance
• Fuel type
• Boost target
• Intended RPM range
• Power target and engine use

For builds chasing the vendor’s 2000+HP suitability note, the 22mm heavy-duty pin and aluminium pin button package should be treated as a critical part of the specification, not an optional afterthought.

Why buy from Prime Speedworks

Prime Speedworks is built around serious performance parts selection, not generic catalogue selling. A piston like this belongs in a properly planned 2JZ engine package where the machine work, rods, crank, head, gasket, fasteners, fuel system and turbo system all support the same goal.

We understand the Australian 2JZ market: street cars making big power, workshops building customer engines, drag and roll-racing cars pushing cylinder pressure hard, and customers who need the right part the first time. With products like Traum Pistons, the value is not just in supplying the box — it is in helping make sure the piston spec suits the build.
