Re: Converting a 1GGTE to 1GGZE Coil Pack Ignition

Well, my initial impression would be no, and the simple reason for that is this.
To run coil packs you must have some form of CAS (Crank or Cam) to tell the ECU where the engine is.
A 1g-gZe must have one of these to tell the ECU where the engine is and which coil to fire. I THINK it has a CAM Angle Sensor.
The 1g-gte has a distributor as you may have noticed. It is from inside this distributor via three different pickups that the ECU is told where the motor is at. Bascially the Distributor is running as a Cam angle sensor.
Now that's all fine, but the 1g-gte ECU is used to seeing where the Distributor is at(Given it's direct drive from the CAM), and when the distributor is at the place it wants it to be it, the ECU will fire the coil.
So, you may say, why don't I just take the dizzy cap off and use the dizzy as a CAS to the 1g-gte ECU. Yes, you could do that, but then you don't have the ignition output drivers from the 1g-gte ECU to fire singular coils. The 1g-gte ECU is used to firing only 1 coil at multiple times per revolution, whereas the 1g-gZe ECU would be used to firing one of six coils(or three if that's how it works) once per revolution.
Long story short, you could convert the 1g-gte dizzy to become only a CAS and hence give the ECU the signal it requires, but the 1g-gte ECU won't have the ignition driver outputs to fire a coil pack.
