if your handy with a soldering iron, you may be able to use those s2 coilpacks. in 32 and 33s1 the ecu sends power to the ignitor which allows the coil to ground itself (makes a spark). if you take the power that was meant to be going to the ignitor pack and route it directly to the coilpack, you may have solved your problem
