Coil on plug conversion with 2jzge cross over intake.

[3tc power]

hello everyone i was wondering if there is any smart coils that can be used on the 2jzge while keeping the cross over intake? i have a mk3 with ms3x and i currently have the zz coils which is way to tall to use with that setup. any input on this subject will greatly appreciated.

Thanks in advance guys

Why not use the VVTi wasted spark?

Because my ms3x is wired for 6 individual coils already for full sequential and i wanted to keep it that way..i really don't want to rewire the harness. if it comes to the point that i just go front facing intake i guess i will. problem with that i have to change intake,FMIC and intercooler piping. well this post is to really see how many options i have before i start changing stuff.

VVT-i coils are dumb coils, so you need a separate igniter somewhere...a step in the wrong direction.
It is said that 1zz coils can be cut about 1" to fit under the 2jz cover...google on that.

I also found this some time ago.... stealthy LS coil project. Just need to get BRANDED coils from a good supplier....many decent deals out there, with fake coils

Thanks for your input.. i currently have 1zz coils on my 7m. They way too tall. Now when they say cut 1zz coil, do they mean the boot or tip the spring is?

You need to confirm this from a different source, but from memory you just cut the boots to desired length. Some minor mods might be needed to cut the springs some as well.

ok cool thanks

I would say LS coil as well too. Ideally you want the Truck coils with heat sinks, then you could just pull the boots from a 2jgte coils and build brackets and go.

For the miata's I know they do the 1zz coils, and it fits well for them, but they have issues at high boost (18+ range)

Also, with the LS coils, you could always mount the coils wherever, and get long wires.

Yeah, LS coils are nice.

But you don't need to buy heat sink style coils...The ones without heat sinks are more than powerful enough, and more linear. Branded coils are very important, maaaany fakes out there.
Keep in mind though that most coils without heat-sinks will auto-fire with dwell above 4ms causing ignition advance. They auto-fire to protect them selves from overheating (no heat sink).
So keep things below 4ms.

With that said... my D514a's could probably kill a horse with that 4ms spark.
It was six extremely powerful sequenced sparks, lighting up my engine bay in test-mode. Just love that MS test mode.

my concern is fitment guys! im just trying to figure out something that might work with the cross over intake..

Ah shit, I missed the N/A intake pipe totally. Thought you where talking about the plastic cover on the GTE models.
Cant see a good way to sort that N/A intake without going CNP (CoilNearPlug) with wires.

Make two bracket for 3 LS coils on intake cam cover. 3 coils fwd of the intake pipe, 3 aft of the intake pipe.
two sets will give you 6 coils.

get Truck coil wires for the LQ motors (they are 1" longer than LS wires) and you are there. That's how I made mine fit... could probably find a picture somewhere..

you have any pictures of your setup Radial?

I need to take new pictures, cant find any now.
Sry.
