Traum Pistons | Toyota 2JZ Turbo Forged Piston Set — STD Turbo, 86mm / 86.5mm / 87mm Bore Options

The Traum Pistons Toyota 2JZ STD Turbo piston set is built for serious 2JZ-GTE and turbo 2JZ engine combinations where strength, cylinder pressure control and real-world durability matter. The 2JZ platform is famous for taking abuse, but once boost, RPM, camshaft size and cylinder pressure climb, the piston package becomes one of the most critical parts of the build.

This Traum piston set is aimed at high-output turbo 2JZ combinations, with the vendor listing noting capability for 1200+HP when used with the heavy-duty pin upgrade. The pistons are available in 86.0mm, 86.5mm and 87.0mm bore sizes, with compression options including 9.0:1, 10.0:1 and selected flat-top / 90mm stroke options. The design also includes deep valve pockets, making it suitable for engines running increased camshaft lift and more aggressive cylinder head packages.

For Australian 2JZ builders, workshops and racers, this is the sort of piston package suited to properly planned turbo builds — not just a stock refresh. Whether the goal is a strong street car, drag setup, roll-racing combination or high-boost circuit package, piston choice needs to match the intended power level, fuel, cylinder head, turbo system and RPM range.

Prime Speedworks recommends treating piston selection as part of the full engine package. Bore size, compression ratio, pin upgrade, rod length, head gasket thickness, chamber volume and fuel choice should all be considered before ordering.

Before ordering, confirm:

• Final bore size after block machining
• Target compression ratio
• Stroke length
• Rod length
• Wrist pin requirement
• Head gasket thickness
• Combustion chamber volume
• Valve lift and piston-to-valve clearance
• Intended fuel, boost level and RPM range

For high-horsepower combinations, the heavy-duty pin upgrade PN: P222350250H should be considered, as the vendor specifically references this upgrade for 1200+HP use.

Why buy from Prime Speedworks

Prime Speedworks supplies parts for engine builders, workshops and racers who need more than a catalogue listing. A 2JZ piston is not just a bore size and compression ratio — it needs to suit the full engine combination.

We help match piston selection to the way the car will actually be used: boost level, turbo size, camshaft profile, fuel type, rod and crank package, machining plan and intended power range. For serious 2JZ builds, that support matters.

Prime Speedworks brings technical product knowledge, supplier relationships and real motorsport awareness to the parts selection process, helping Australian builders choose components that make sense for the complete package.
