Hi all. Think I am having issues with the ignition system on my R34 GT-T. It has Splitfire coils but I am pretty sure I am having ignition breakdown on one of them once the boost goes past 14-15psi. I had the exact same problem in my old R33 and that was later tracked down to the factory ignition coils. Car drives really good and even on partial throttle it will pull quite well but as soon as the boost starts to climb, the engine note changes and the power drops off massively with almost jerking hesitation. It will still rev out (I only went up to 5K) but you can tell it just hated it.
I inspected the ignition coils and two of them look to be much newer looking than the other four. Just cleaner looking and the blue colour is much brighter. I am pretty sure someone has been in here before and maybe changed a couple of failed coils. Spark plugs all looked pretty much the same. Couldn't see any difference there.
For the guys with tuning experience, would I be ok getting the R35 ignition coil kit and just fitting it in there. I don't want to mess about with the Splitfire ones any more. Could I drive it like that without adjusting dwell settings? If that isn't a good idea could I at least drive it to a tuner with R35 coils fitted? I have bigger plans for the car down the line but currently it is tuned for just under 300kw on e85 with GT3071R pushing 20psi. I want 400kw down the track so an engine rebuild and turbo upgrade will be in the pipeline. I just want the car to run to its full potential for the moment.
Sorry for the long post guys but just wanted to give as much info as possible so that you can give me the right advice. Thanks for any help.
