So from what i've read here, the 1NZ coils will work with a 1JZ JZA70 stock ecu? All thats needed is the loom and the bracket? What about the stock ignitor...not needed anymore? Is there anything that takes its place? And can the tachometer work without the stock ingnitor? I'm quite interested in your loom and bracket, kindly pm the price. Hope you can shed some light on these questions I have as I dont really have a deep understanding as to how the ignition system works. Thank You.
