Wiring Specialties now carries coil-on-plug "Smart Coil" GM coil conversions for the 1JZGTE Non-VVTi engines. This is a major upgrade in spark performance over the stock ignition system. This system eliminates the ignitor and replaces the stock coilpacks completely.
The stock Toyota coils are getting old, replacements are expensive and usually need to be shipped. LS Smart Coils can usually be found easily in local parts stores. Eliminate potential downtime waiting for expensive Toyota replacement coils to arrive.
Wiring installation is plug-and play in the stock location with a Wiring Specialties PRO Main Engine Harness with the Add LS2/LQ9 Coilpack Conversion Harness Option selected.
Installation is typically drop-in but some 1JZs have different head castings and you will need to drill and tap a few shallow 6mmx1.0 holes for mounting points. If you have any concerns, please email us an overhead picture.
- This conversion setup MUST be used with the Wiring Specialties PRO 1JZGTE Non-VVTi Main Engine Harness with the addition of the Wiring Specialties LSx Smart Coil Conversion 1JZGTE Coilpack Harness option. It WILL NOT WORK with the stock OEM Factory engine & coil pack harnesses.
- If the kit is being installed on a JDM Supra or Aristo, a tachometer adapter such as the Dakota Digital SGI-8 will be required to restore tachometer functionality, as the tach on these cars is driven from a high level output from the (now deleted) ignitor.
- These coils will work with the stock 1JZGTE Non-VVTi ECU, but need an additional IGF box to synthesize the required IGF signal back to the ECU. Please contact us for details.
- Use with an aftermarket ECU is recommended and is 100% plug-n-play.
