Part 2 is coming soon and will take things to the next level. The plan includes fitting a 3-bar MAP sensor, or possibly upgrading to a Haltech Platinum Sport 2000 ECU with launch control, anti-lag, and a host of additional parameters.

Once the 3-bar sensor and revised ECU setup are in place, boost will be raised to 1.7 to 1.8 bar. Power is expected to be in the region of 700 horsepower and beyond. Watch this space for more on this incredible 2JZ-GTE Supra build.

This auto-box Toyota Supra rolled in for calibration on its fresh GT35R setup — and even on a conservative 1.1 bar base map on the AEM ECU, the results were exactly what you expect from a healthy 2JZ-GTE: effortless power and mountains of torque.

? Current Output (Base Map @ 1.1 bar, GT35R)

• 492 hp (engine)
• 469 ft-lbs torque
• 416 whp
• Automatic transmission
• GT35R turbocharger

For a baseline pull, the setup is already delivering strong, clean numbers with plenty of headroom left. The GT35R pairs beautifully with the 2JZ — quick enough to keep the auto box happy, yet big enough to push well into the 600+ range once the rest of the build catches up.

? What’s Next?

The owner’s booked in for the next round of upgrades:

• 6-speed gearbox conversion
• Full remap for 2.0 bar target
• Revised boost control & ignition strategy
• Fueling tweaks to support the higher load

Once the manual swap is in and we push toward the 2-bar setup, expect a completely different animal. The GT35R wakes up hard above 1.5 bar — and paired with a proper 6-speed, this car is going to transform from “quick” to “seriously fast.”

? Final Thoughts

Even in base-map form, this Supra proves once again why the 2JZ-GTE remains the gold standard for tuning. Smooth, predictable power delivery, instant response once boosted, and the headroom to go from sensible to savage with just a few hardware tweaks.

Stay tuned — the next visit with the 6-speed and high-boost calibration will be a whole different story.
