    coil on plug conversion?

    I've searched for a while now and can't find a good source of info. What coils are used when a COP conversion is done on an S14? From the pictures I've seen, it doesn't appear as though any conversion brackets are used... :???:

    I've never seen an S14 with COP. Can you post some pictures?

      These might work, and LS2 coils are fantastic. they're logic level inputs, which is nice since you don't need a bunch of extra hardware to drive them. Just a logic level signal and power to the coil.

        Those do look promising... I'll look for some dimensions...

        These are what caught my eye.

            i took these shots at the socal vintage show
            i saw the car for the first time in irvine ca at cars and coffee.





            here is a crappy blurry picture that could be used to identify the car if anyone knows who the owner is.

                  Wow thats cool then. I agree it looks like a cleaner setup too.

                    Looks like he's probably fully sequential too from the looks of that cam sensor...

                      yeah, otherwise it would be wasted COP (as in, 2 COPs fire in pairs).

                      cam sensors are actually really easy to setup. at least, mine was.

                        Cop

                        My understanding is that some people have also revised the S38 3.8 cam cover to get a factory look, and factory style/age/generation coil installation.

                        I bet there are good photos and info in S14.net on the subject.

                          That silver m3 is owned by the owner of Bavarian WorkShop in west hills.

                            Marc of Bavarian Motorwerks kindly showed me how he'd done his and sent me the parts to convert mine, but I thought as I wasn't going to need my old red Ultra leads any more, I'd have a go at adapting the ends first.
                            The result came out pretty good.

                            This is what I started out with:



                            First I unscrewed the HT heads from each plug cap. I then
                            carefully measured exactly how long I needed to extend, peeled back the silicone cover from the plug cap, then took a small angle grinder and carefully lopped some of the excess off then slowly ground it down flat, till I had exactly the right length.



                            Next, I took a small drill bit (Matched for tapping an M4 thread afterwards) and drilled into the copper recess where the end of the HT lead had screwed into.
                            Then taking an M4 sized die, I cut a new thread.



                            Using a longish piece of M4 screw, I cut to size so I could screw one end into the newly finished copper thread using long nosed pliers, then insert the other end into the coil pack's retainer. The top of a spark plug is M4 sized, so it would insert nicely.
                            Once temporarily assembled, I inserted into the spark plug hole and tried it for size:





                            I then cut off the excess red silicone insulator (See picture above) and used the coil pack's original black rubber insulator, to tightly squeeze over both plastic ends, glueing the bottom part onto the plastic with Superglue.

                            The coilpacks would have rattled in their holes so I took 4 small O'rings for each unit, pulled the original coilpack's plastic cover down slightly to make a small recess and used the O'rings to make a perfectly fitting cushion.



                            4 Finished coilpacks:



                            I intend to use the original HT lead's long box to house the new wiring and keep it looking factory. I didn't machine the circular insert flat, as this would make the connectors too low for the long box.



                            Now I need to find a weekend to work on the car - so I can get the entire harness changed and all wired in... Maybe end of September, or beginning of October.
