MYSTERY 2JZ FINALLY HITS THE DYNO!

Summary

The video shows the process of getting a turbo 2JZ engine running in a Toyota Supra after completing the swap and install. They start by getting the engine running on the dyno, tuning it conservatively on pump gas to around 500 horsepower. After resolving some initial issues with the turbo boost control, they achieve a strong yet safe power curve. They then drive the Supra and test its new power, pleased with how it performed. Overall it seems the 2JZ engine swap went smoothly and the Supra gained huge power gains while retaining its drivability.

Takeaways

• 😀 They got the 2JZ engine running for the first time recently
• 😊 The intercooler piping and bumper are now installed
• 💪 The factory cluster and power steering are working thanks to Wiring Specialties
• 🚗 The car runs well but still needs some tuning and setup work
• 🏎 They dyno tested it and made around 500hp on pump gas at 18psi boost
• 🔧 The dyno needs a new load cell but can still be used without it for now
• 👍 The power curve looks good but they need to tame the torque spike
• ⚙️ The turbo works well but the boost control needs more tuning
• 🎉 They did some test launches and donuts to celebrate the initial dyno runs
• 🚘 Overall it ran well on the first startup but still needs finishing work before it's road ready
