TUNING THE TOYOTA 2JZ (JZA80)
Toyota Supra 2JZ-GTE – GT35R Auto Setup Making Serious Numbers
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.
