Supra — Stage 3 ECU Tune
- 1118 hp output at 35 psi boost
- Full engine build delivers extreme reliability under high boost pressure
- Ported head and Kelford cam combination optimizes cylinder head flow
- Turbosmart 7675 turbocharger enables peak performance across RPM range
- Haltech 2500 ECU provides precision fuel and ignition control
- Plazmaman intake manifold improves air delivery efficiency
This is a full GE-to-turbo conversion on the 2JZ, anchored by a Haltech 2500 standalone. The workshop delivered 833 kW at the wheels and 1172.8 Nm, running 2.41 bar through a 76mm turbo. Calibration focused on holding timing stability under sustained load and managing IATs across the higher boost window.
The Haltech platform gave clean control over cam timing and sequential injection staging, which mattered given the ported head and upgraded valve train. Fuel and ignition tables were dialled for closed-circuit use, where thermal load and transient response are priorities over street driveability.
This file suits workshops building similar GE+T Supras for competition or dedicated track cars. It's a reference point for high-output 2JZ calibration on modern standalone ECU hardware.
What fuel was this tune calibrated for?
Fuel type was not recorded with this build. Workshops should confirm target fuel with the customer and request a corresponding file if needed.
Is this file suitable for street use?
No. At 833 kW and 2.41 bar, this calibration is intended for off-road and closed-circuit competition use only.
Can this file be adapted to a stock-block 2JZ?
No. This tune assumes a full engine build with upgraded internals, head work, and supporting hardware as listed. It is not safe for factory components.
This calibration was developed for a workshop like yours
The Toyota Supra above was calibrated by Protunes for a partner workshop — they did the vehicle work and kept their customer; we did the calibration engineering on the Haltech 2500. Add professional ECU and TCU calibration to your workshop without employing a calibration engineer.
