Exact same thing happened to mine with what seems the common set up in this thread, on a standard rb25, gt30r turbo with external gate running with a wolf ecu. The same thing happened to me a couple of times, but I found only before the engine warmed up. Before you think it, I don't thrash my car when it's cold, but it only did it not long after start up. If it didnt make a huge bang & shudder, it would just pop from the exhaust. This hadn't happened for a while before my engine let go, so this wasn't related to it. From a bit of research & the symptoms of them, chances are it's the standard coilpacks causing this to happen.
But this NEVER happened after I had been driving it a while, only in the first 5-10 under mild acceleration.
