Another long-term plan could be accelerated through the discovery of a sweet deal, I've found some LS1 coil packs on a harness for a 4cyl CoP setup:

Through some quick googling I've found a few people saying they're running LS1 coils on a 4AGE but no pics. The 1ZZFE coil packs are the more popular option. Anyone know how these things fit? There won't be a whole lot of clearance between the valve cover and hood.

Answer found, they don't mount directly on the plug, you still need plug wires:

It would be good for an offroad car (so you could seal the coil packs away) and is probably better for longevity.

The 1ZZFE setup saves underhood space (in total, but reduces valve-cover-to-hood clearance), the downside is you have to modify the valve cover:

Since those coils use spark plug wires, you should be able to mount them in just about any position, as long as you have long enough plug wires.

EDIT: I see you found the answer already, looks like a cool setup.

Think I'm gonna hold out for 1ZZ-FE coil packs. No way I could get LS1 stuff locally.

They can look cool too, my finished engine would look very similar to this:

What are you going to control it with? I run 5SFE Camry coil packs on my 20v 4AG in waste spark, controlled by MegaSquirt.

Another option - LS1 coils on the valve cover:

In a typical GM fashion, I highly doubt LS1 engines use different coil packs than the LS style truck engines.

There's just as much local support for GM trucks as for Corvettes, that is, zero

I don't understand......... why run COP with a wire?

Where the hell do you live there there aren't 1000 ls powered trucks within 5 miles? There's one in my driveway and I can look out the windows and see three other ones and a ls powered camaro in various neighbors yards.

The truck stuff is actually hotter.

One thing I liked about the LS1 packs is that I retained the GM sub-harness, so I only had to wire in a single plug that ran all 4 coils. I was able to get that plug and pins from Ballinger.

Barbados. Toyota trucks are more prevalent.

LS1 and LS3 coils are different, too. The engine family's been in production for a decade and a half in a huge variety of applications, remember.

We put LS3 coils on Miata engines. We mount them on the back of the valve cover. The LS3 coils are a lot smaller than the LS1 units, and we can pack four of them in the place of two Miata coils.

Have you looked at the Ford coils from the 4.6 / 5.4 V8's? They would be a true COP. You would have to make up a mounting bracket but since you are fabricating already maybe it is an option?

I have a couple bad ones lying around if you want to play with them. they are yours.

Haha shipping would kill you and I'm trying to stick to Japanese stuff since American cars aren't too common here and junkyard/parts store support is poor. I'll go for 1ZZ, I only considered something else because I noticed a sweet deal.

Hmmmmm, I'm running an older GM coil assembly.... not as light as the COPs... but it does plug in with just the GM plugs....

mounted low on passenger side just above the frame rail

In the case of a typical pushrod Vx engine, coil near plug (CNP) makes plenty of sense. Reliability, packaging, cost, etc. Try getting a set of coil packs to survive hanging off a Vsomething while cantilevered above the exhaust manifold and you'll get it.

In a DOHC I4 a coil ON plug makes much more sense, which is why it's so common. In the case of retrofits and aftermarket stuff, there's a TON of CNP stuff you can get for cheap that performs great, has good documentation, and packages easily, so you see a lot of them even in retrofits on DOHC I4s (as shown above).

Dave...hate to hijack the thread, but can you tell (or link to) more about this setup on the D16? Curious what engine management is being used and with what timing sensor(s).
