    Re: Coil-on-Plug Coils

    math? dude those coils are known for failing with 0 miles on them right after leaving the dealer's lot. If you want those coils, you need to find 3-5 year later versions IMO.

    Meanwhile, did you ever address the fact that they won't work on a turbo four? or haven't you opened the hood to your car yet? :D

      Actually I have, with the stock intercooler they wouldn't work, but if I deleted the stock intercooler and put a bigger intercooler up in the front of the car there would be room.

          The late model Toyota COPs are pretty popular in the Miata world but only seem to be good for somewhere around 15-20 psi. They seem to be as much a cosmetic thing ("Hey, look, no plug wires!") as much as a real performance mod. The coil near plug setups are often hotter as they use larger and better cooled coils.

            So using the LS1 coils that I have would be the better way to go??

            I'm hoping to buy that MS in the next couple of months, it's going to fun putting that together with my oldest and then we get to learn together in how to program it. At 13 he's going to get an early start. ;)

              I think that would be the better plan.

              And starting them early is always a better plan.

                Yep, LS1 coils seem to be hotter than any coil-on-plug coil with built in ignition modules.

                  There is another alternative that works well if you are using an MS2 wasted spark set up. I have two four tower coils from Pantera EFI (also the source of the legendary ICN's) which require an out board igniter, mine is made by EFI Source, and run more conventional plug wires, FireCore50's in my case.

                  I mounted the coils in the spot vacated by the distributor (in front, its a BBF) and the plug wires loop around the front of the valve covers, the harness sneaks back under the throttle body.

                  This allows me instant access to the valve covers to check lash and such and IMHO makes the engine look cleaner. Its very easy to service and check things should there be an issue. That said the setup has been bullet proof since we first set it up 2.5 years ago. The big issue for me was cleaning up the electrical system to keep extraneous voltages out of the RPM signal.

                  All part of the fun in a first time EFI conversion.

                    Re: Coil-on-Plug Coils

                    I keep thinking of going to a distributorless ignition in the Skylark, then going to a points distributor just to turn the oil pump (or see if a 3.8L cam sensor can be modified for that duty). My hang up is actually making or mounting a trigger wheel. I have no fabrication skills or junkyards near by to start pirating trigger wheels. The TA timing cover comes with a threaded mount just for holding a trigger wheel sensor bracket though.

                    The OHC Pontiac engine I'm 90% certain I'll be going distributorless ignition on that too.

                      Randal, I'm happy to help in any way I can. I think the Hamlin sensor DG has written about would be a good place to start as the body is threaded which simplifies making the mount. See my post in the Crab and EFI combo thread.

                            The sensor and wiring is the easy part.

                            It's the fabrication of the trigger wheel that could be trouble. I have no fabrication skills (I can't make a straight line even with a ruler, lets not get into circles and centers...) and I wouldn't trust my welding as of yet.

                            Application is going to be subjective, no one I know has done it on a Big Block Buick. I put a thread up on the V8Buick board for some feelers.

                            I'm going to CA this weekend, I'll bring some pulley pulling tools with me, and maybe will just go nuts pulling several trigger wheels. Mark, I still haven't mailed you a check yet :-\

                              I did the same kind of thing, notched it for the crank key with 3 hacksaw blades hung in the saw frame. didn't have a brotch.
