Why You Need This

The 2JZ's factory individual coil setup requires precise ignition timing control, especially when you're pushing beyond stock power levels. Generic universal harnesses often result in voltage drops, misfires under boost, or outright failure when heat and vibration take their toll. This purpose-built harness uses the correct HPI6 connectors that mate directly to your factory coil packs, maintaining the OEM connection integrity that's critical when you're running aggressive timing maps or high boost pressures.

We've seen too many 2JZ builds suffer from ignition issues traced back to poor harness connections. Whether you're installing an Elite 2500 in a MKIV Supra, completing a 2JZ swap into an S-chassis, or building a high-boost single turbo setup, this harness eliminates the guesswork. The factory-spec connectors ensure proper contact resistance whilst the professional-grade construction withstands the heat cycling and vibration that kills budget alternatives. Essential for any serious 2JZ build where reliable ignition timing is non-negotiable.

ECU & System Compatibility

Specifically designed for Elite 2000 and Elite 2500 ECUs controlling Toyota 2JZ engines. The HPI6 connectors mate directly with factory 2JZ-GTE and 2JZ-GE individual coil packs. Not compatible with other Elite series ECUs or different ignition systems — contact our technical team to confirm compatibility for modified or non-standard 2JZ applications.
