It’s dangerous to go alone. Take boost. Introducing RAD's, The Legend of JZ
PSI Hard Series | Turbocharged 2JZ | Targeting 800+ HP | Includes Engine, ECU, Wiring & Final Tune
In development · Expected Q1 2027 · Estimated starting price: $18,499
The Legend of JZ starts with a 2JZ-GE VVT-i and turns it into the turbo straight-six you built the car to have. Forged internals and a single turbo are paired for a hard pull through the midrange and the kind of top-end charge that made the 2JZ famous. It’s serious power with a clear goal: a car you’ll want to drive, not just put on a dyno.
RAD develops the engine and its controls as one combination. The package brings together the built 2JZ, turbo hardware, fueling, standalone ECU, engine wiring, flex-fuel capability, closed-loop boost control, protection strategies, and a completed RAD tune. Your installer can focus on fitting the engine to the car instead of developing its fuel and boost control from scratch.

- Includes ECU, engine wiring, monitoring sensors, and completed RAD tune
- Broken in and dyno tested before delivery
Built for the Way Boost Feels on the Street
The aim is a broad, responsive engine that builds from everyday driving into a forceful midrange and keeps pulling up top. The turbo, camshafts, fueling, and calibration are specified together so the power feels deliberate and controllable.
Startup, warm-up, idle, part-throttle response, boost transitions, and full-power operation are all part of the development program. The goal is a finished street engine with the headroom to make big power when you ask for it.
Built 2JZ-GE VVT-i Engine
Each engine is disassembled, inspected, measured, machined, and assembled for its intended turbo combination.
Engine Assembly
- 3.0L 2JZ-GE VVT-i inline-six
- Block machining and cylinder finishing as required
- Forged pistons and connecting rods
- New main and rod bearings
- New oil pump and timing components
- Upgraded main and cylinder-head studs
- Performance head gaskets, new seals, and assembly hardware
- Measured and set critical assembly clearances
Cylinder Head and Valvetrain
- Inspected and machined cylinder head
- Performance camshafts and matched valve springs
- Verified spring installation and valvetrain clearances
- Performance harmonic damper
Induction, Fuel, and Turbo Hardware
- Forward-facing intake manifold and drive-by-wire throttle body
- Fuel injectors selected for the turbo and flex-fuel combination
- Single turbocharger, wastegate, and engine-side turbo hardware
- Spark plugs and ignition components matched to the engine
ECU, Boost Control & Final RAD Tune
The included standalone ECU and engine wiring bring the fuel, ignition, VVT-i, flex-fuel, and boost systems under one control strategy. Fuel-pressure, oil-pressure, and oil-temperature monitoring support the engine-protection strategies; closed-loop boost control is included as standard.
RAD develops the tune across startup, normal driving, fuel blends, boost, and full-power operation. Each engine is broken in and dyno tested before delivery.
Oil pan and pickup configuration, accessory drive, charge plumbing, and vehicle-specific installation parts are selected separately to fit the car. The starting package includes startup oil and a filter.
