Hey guys Im after a set of coil packs to suit my RB25DET series 2 R33. I just ask that they are 100% working, im in newcastle but im willing to pay postage. So hit me with what you have. Cheers Alex -
I was having trouble with my R33 breaking down but only when I tried to run high boost (24 psi) Running at 12 psi it was smooth and faultless so I changed plugs, fuel filter and a few other things but nothing worked so I took it to Gavin wood and he said the coil packs were more than likely at fault. Rather then shelling out and purchasing another set of coils OR gaping my plugs down from 1.1mm to .6mm I did some more research and found some people in the UK were making up Acetal plates for mounting their coils too and this was solving a range of problems for people. The theory is that when your coils fail they are finding the easiest path to earth for the spark to travel OR when you are running boost over 1 bar the spark can be "blown out" basically so the simple fix is to get more powerful coils BUT If you think harder about the problem and rather than resorting to fixing a short with "more power" to make up for it, actually remove the path the short is going to take and you will find all your power will now go straight into your plug!! From the minute I started the car even driving round on 12 psi it felt so much crisper and more responsive, but the proof was being able to run 24 psi again revving clean and clear right to limiter. Acetal or Polyoxymethylene, is an engineering thermoplastic used in precision parts requiring high stiffness, low friction and excellent dimensional stability. All you have to do is trace your alloy ones onto the Acetal plate and you can then cut them out with a jigsaw and tap the holes. I made mine in house and would consider making up a run of these should people not wish to stuff around making their own and would rather to just purchase them. Hope this gives you guys another option to try at home when trying to sort out your misfires.
