I made an aluminum plate to attach my coils to but I guess my coils are too short or something because the coils will sit flush against the valve cover but they won't "snap" onto the plugs when I have the plate between the coils and the vc. How'd you guys get around that? Longer plugs?
|
I think that's why we make the brackets, because COPs don't click into the spark plug. Make sure to countersink your bolt holes, and trim any plastic that may be keeping your COPs from sitting as low as possible.
|
You are correct sir. ^
|
Ya I trimmed the sides of the COPs so they fit without touching the sides and they do click right now but not when the plate is on, like they don't reach down far enough or something. So when I do get the plate on and the screw holes drilled will it still make good contact to the plugs even though they don't "click"?

instead of a plate, make two L shaped pieces of metal with holes at the top above the coilpacks, run a small piece of metal between them to hold the cops in tight.

Golferluke, they'll be fine. Trim the plastic, as you said, put them through a 1/8" aluminum bracket, bolt them to said bracket, and bolt the bracket to the 3 valve cover screw holes. This is exactly like the other COP thread tells you too. It'll be fine. |

This is exactly like the other COP thread tells you too. It'll be fine. "This month's DIY Stud of the Month (SOTM) is Publio Morera for his cheap and easy solution to holding down individual coils on his NA Miata. Early Miata guys often convert to COPs, particularly the turbo Miata guys who need to improve their ignition system to fire off those boosted intake charges once they approach 14psi or so and start to blow out what the stock system can provide. If you've got aluminum welding skills of course you can weld hold down studs, or take it somewhere and have it done. Or, you can be a DIY Stud like Publio here and use a couple aluminum brackets held down by the center valve cover bolts, with a rod threaded through and a bit of padding/rubber above each coil to dampen vibration. The rubber cap (a vacuum cap) on the end prevents the bar from sliding out of the bracket from vibration." |
Ha that's sweet but I think I'll just use my plate. What's the best way to countersink it?
|
Make the holes large enough so that the coils go through the plate and rest on the valve cover. You need the plate there to hold the coils down, and it will do just that. That way the coils will not be too high to jeopardize the connection between the tip and the spark plug.
|
Cool thanks. I've got my plate all made and ready to go, just haven't made the holes for the bolts that hold the coils down.

Or you guys could get the slightly longer ones and it makes for an easy bottom mount plate.
I picked up a set.... or dozen.... http://i295.photobucket.com/albums/m...e/5b64194b.jpg |
how long did it take you to arrange your swastika?
|
Ok so here's a question. I'm not running a cap on mine. And recentley I've been having mis-fire issues. This is on a MS1 running 2.5ms dwell.
Would adding a 10000 cap possibly help? Also, is there any way to check they are still in factory spec? |

So at this point my plan is to work on getting bottom mount plates made up for 1.6 and 1.8s. I'm also doing at least one PnP (igniter hollowed out) 1.6l set. The rest I'm intending to do as DIY/PnP... 7 wire... with weatherpack for easy removal and pigtail out of weatherpack for wiring in. This would allow for sequential installs and then by just joining 4 into 2 (cylinder triggers) you get normal wasted spark.
How does that sound for people wanting a basic solution? Thoughts? Mind you... i will not do a waiting list. As they get built, I'll post them up. I'm not a business, just a guy making these on the side. Please don't ask for dibs :P (that includes those already saying 'dibs' :P ) |
No dibs, but I'll send you a deposit.
