Hello All,
My mate has a Series II R33 and he running stock boost. He has had problems with it breaking down so bad at 5000 RPM that is wouldn't rev past that point (it has only been doing this for a few weeks). I suspected buggered plugs so i go him to get a set and i when to put them in this afternoon, expecting to find one of two shagged plugs. To my surprise when i pulled the old ones out they were iridiums and they were all in really good condition with good colour. The only thing that would have been better was the gap which was around the 1mm mark.
So i started looking for other problems, when i pulled the boots off the coils packs none of them had the graphite electrode in them that i expected to see, (I have a CA18det 180sx and my coil packs have the electrode in them). I called one of my mates who has had a few skylines and he said that he would have expected the coil pack to have had this electrode.
So the Question is; "Knowing that the Series II 33's had slightly different coil packs do they still have the graphite electrode?"
The pic's;
Back three Coil Packs (they were all the same);
One of my old CA coil packs;
Anyhow i gapped the copper plugs he bought to 0.8mm and chucked them in and it does now rev out, but we could load the engine up because it's wet and it just spins up. If the coil packs are supposed to have the tab in there when he starts running some boost then i suspect he will start having spark problems again.
