JZ coils and standalone EMS's
- Thread starter becauseican
- Start date
They would be only if you run a standalone EMS, these will not work correctly on a stock ECU setup as you cannot adjust the dwell setings. This goes for 1jz's and 7mgte's. 7M's dont normally have spark problems.
Yeah, I remember seeing that as well. Anyone know of a good thread that discusses other options for the 7M? Or maybe just getting rid of the multiplex igniter is enough...
BTW- The idea of heatshrinking the coils is a very cool one, indeed. I also read about that somewhere in the 96 pages of the "Project Clean 87" build thread.

This might be a great buy and better fitment as it is direct replacement

Whats the partnumber of the coils BIC and honestabe use pls chime in because in this link http://www.motec.com.au/forum/viewtopic.php?f=19&t=374
The part number on the coil is denso 90919-02230
Butt i can get a set of coils but its an different partnumber the last number end with an 9
This is the partnumber of the coils 90919-02239 are they the same ??? can i use them ?
Bic use late Mr2 coils so i think ( 90919-02239 ) is the right one (somebody correct me iff i wrong)
The coils listed in the Motec link are from lexus right?

I use 1zzfe coils. The 1zzfe and 2zzfe coils will work with this setup.
Quick search on Ebay gave me this
Manufacturer Part Number: 90080-19015
Other Part Number: 90919-02239

Can I use these on my 2JZ GE-t swap with an AEM? I don't want to the dizzy or 7M electronics.. wanna run the 2JZGTE AEM... If I do I wont have to run an ignitor if I'm reading this correctly?
Thanks
Ryan
Thanks
Ryan
Yes, these would work great on the 2jz with the AEM. Each coil has an ignitor built in, so you can loose the stock ignitor and you also wont need the DLI, that the AEM ignition "requier's" at higher boost levels. You should be able to run it in full sequential ignition then, assuming it has 6 ign outputs.
now what i've read 2 times and seen a picture of 1 time, the 1zzfe seem to sit an inch over the valve covers on a 7mgte now how about this, i got this info from http://www.ae86drivingclub.com.au/forums/showthread.php?7098-Toyota-Coilpack-info-thread but in short these are all different styles of 1zzfe cop units
These were put with the rubber seals more or less in the same plane so you can get an idea of comparative height.
Source vehicles and part numbers from left to right:
90919-02227 ST215 Caldina 3SGTE
90919-02230 GXE10 Altezza AS200/Lexus IS200 1GFE vvt-i
90919-02239 ZZE120 Corolla 1ZZFE
90919-02240 NZE121 Corolla 2NZFE
90919-02236 SXE10 Altezza RS200 3SGE Beams dual vvt-i
you guys think a shorter one of these will work height wise on a 7m?
btw i have a vipec v44

I have found alot of information on this talking to engineers.
DLI works its like CDI it ramps the voltage up on factory COP plugs
DLI can only kind of help direct fire plugs such as the ones with ignition chips built into the coils such as 1zzfe coils
So 1ZZFE coils are only an upgrade in low HP applications and when you want to clean up the engine bay by not having coils & ignitor packs spark plug wires every where .
You must used sequential firing ecus not batch fire.
You must also use quality plugs like platnum plus perferably iridiums.
You can upgrade JZ coil packs using the new superspark COPS from australia they are actually cheaper then NEW JZ coilpacks and give a 10%+ spark boost.
For a JZ setup I plan to use
These COPS
With HKS twin power modules set up for sequential.
With sequential ignition standalone managment(non waste spark)

Randy/Honestabe/Suprahero (even IJ): I've tried to find the dwell time for the 1zz coils on the 'net, but I haven't had much luck finding concrete info. How many m/s of dwell are you running? I've seen 1-2m/s for JZ coils, but these aren't JZ coils. I have 3.5m/s dialed in now, but I think that it's way too much for 1zz coils
I'll have to plug my laptop into my standalone to be able to tell you. I'll try and let you know within the next couple days (very busy).

Are these coils "smaller" than jz ones? I'd drop that down to 3.0 which is typical setting, a good starting point. Too high or too low can cause weak spark or overheated module. Smaller coils usually are set to ~1.8. HTH

I was thinking more of setting it at 2.25 - 2.5 m/s, but now even that might be too much. I'm going to have to do some digging on this on, COPs aren't cheap
Mark, I don't know if it's right nor not, but my dwell is set on 3.25ms. It's been like that for a while now with not one single hiccup. I used to think all supras broke up under wot until I got these 1zz coils..........lol

I don't know what is consedered low horsepower, but my car has ran flawlessly with the used 1zz coils that I bought from ebay. I run 24psi on a daily basis with a billet 6765 making about 640rwhp. I haven't dyno'd the new 6765 yet, those numberw were on my pt67 but I doubt they've gotten smaller. I haven't had one brake up under boost like I used to get. These coil packs are one of my best upgrades on my car.
I also run the ngk plugs and not irridiums.
We normally run 3 ms on sequential ignitions, this is what I run on my car. I have run up to 27-28 psi with .030 plug gaps with zero issues, this is also on NGK copper BKR7E plugs that I have been runniing all year....about 50 dyno pulls, 5+ visits to the track and daily street driving at 20 ish psi (500 HP). With the stock coild I was changing the plugs every few weeks!!
Here is the dwell settings recommended from the Motec forum:
The dwell should be set as follows:
8V 6.3 ms
9V 5.3 ms
10V 4.4 ms
11V 3.8 ms
12V 3.2 ms
13V 2.7 ms
14V 2.4 ms
15V 2.2 ms
I am not sure where Evilempire is getting your info from but these are an amazing upgrade to our ignition systems (not just for looks), assuming that you have an standalone ems. This setup will not work on a stock ecu. Most stock JZ coils are 10-20 years old now and cracked and break up at more than 17 psi boost. These coils are a great alternitive to buying new coils, plus a HKS DLI just to make a decent spark. You can find them at any junk yard for under $100 for 8. yes I agree that the stock coils are fine if they are brand new, but normally you also need a DLI to make them preform under high boost.
BTW I still have a few of the mounting bracket sets for you guys if you need them.
