I was reading some magazines, and saw that the ignition upgrade that was used mostly on the Z32 was the HKS twin power ignition. I wanted to install one but i did a seach on it and read that a few people were having problems with it,saying that it miss fires at high RPM , idle's bad some times and that you don't need it, most of them converted back to the stock ignition. How true is this? I see that the wiring diagram on the tech page is for the 1995 TT model , would the wiring for the 1990 TTmodels be the same? If by chance it is different for the older models does any one have any links or pictures for the installation? And does it really make a difference on the throttle response?
