1zz-fe coils not fitting my 05 NB
Hello, well read the section where it has how to do the COP conversion so i decided to go for it.. Got the correct coils and clips but when i went to slide them into the spark plug hole, they seem to have been too thick to fit.. Now i thought the only modification was to add bolt down things on the valve cover but do i also have to bore out the cover to fit the coils? or does this not work for the VVT NB?
Thanks for your help

There are a few other COPs out there that are smaller diameter but their mounting tabs and igniters may be a problem...Could the stock 01+ COPs be modded, such that you pick up 2 more and put them in the other cylinders to run sequential???...smaller ones may be like some Audi/VW...anyone positive on their reliability or output? (Toyota ones I'm told can throw a spark like a lightning bolt haha)
This thread shows them...

Don't sweat cutting up the valve cover. You just have to enlarge the holes to fit the coil shafts. Doesn't hurt anything.
But you will have to modify the coils where they sit at the top of the valve cover.

*And if one wanted to run full sequential ignition, then could 2 more of the stock VVT Coils (~$60-$70 total) and place them on the currently "wired" plugs? Then just cap the outlets on each to "clean it up." Seem legit? I would imagine that 4 of them could fit?

Flyin' Miata makes it work all the time...
Its just a traditional coil pack that you mount somewhere and run plug wires to your plugs...just like every non-COP car or truck. The difference is:
1. You can run full sequential ignition (REQUIRES ENGINE MANAGEMENT), in which each coil/plug only sparks when it needs to for its cylinder, instead of wasting every other spark to an empty cylinder as ours do (wasted spark configuration - 2 coils, 4 plugs, coil ignites 2 plugs at once, one to a full compressed cylinder the other to an empty compressed cylinder, 1&4, 2&3).
2. More spark...they pack a punch, which is great for boosted cars.
Everyone loves the Toyota COP conversions because the coils have proven reliability (unlike most pre-2001 Miata coils), a higher-energy spark than stock coils, and you can run them in wasted spark configuration if you wire them to do so and will not need an ecu to control them (but that gets into issues with dwell time and burning them out if you don't lower it).
Best of luck with suspension though! My focus is the same right now.
