Rb 25 neo repeated coil pack failure

[Yummypiee]

Hi, I've got a 1999 stage with the normally aspirated RB-25 Neo engine. I have changed the coils and the coil pack wiring loom. However within the last 10,000km it's burned through 9 coil packs. 

Anyone know of any issues that could be causing this and/or potential solutions?

What type of coils are dying? OEM? Good aftermarket (ie Splitfires)? Dubious aftermarket (ie, yellow/red/rainbow)?

You also need to see if the coils are still getting power after the ignition is switched OFF.  If they are then this will burn a coil out.  Long shot but who knows what your wiring is like after turbo timers and alarms etc have been installed and removed etc

It's had a mix of various coil packs, some new OEM, some red, some pink, some scavenged off part cars/breakers.

It's possible, the car does have an aftermarket alarm fitted. What would be the appropriate way to go about testing this?

Wiring diagram and a multimeter.
