Uprated Ignition Coils for 1NZFE

[Parmas]

I am currently running my turbo 1NZFE with phased sequential injectors with a wastespark coilpack. Since this setup do not match full sequential operation I wish to know what direct ignition coils are available out there.

The only three I found are:

Okada Coils -

Splitfire coils -
http://www.rhdjapan.com/splitfire-direct-ignition-system-coil-packs-1nz-2nz-2az-54649

AEM coils -
Garm setup

Is there any other out there?


Another option is to add another coilpack and using 2 leads of each coil while the rest conclude to a wasted spark

Do you know the price range of these OBXR? ^^

[d1nzfe]

$199 at ebay

[Parmas]

do you have a link of them for specs?


Don't bother ..... after I read this .... http://www.thegalantcenter.net/showthread.php?t=39457&highlight=obx

Why not use the OE Yaris coilpacks? Proper fit, reliable, available... what am I missing?

I am trying to get information on better coils than OE. Also I am not sure if they can keep up the charge at higher boost levels....

[Loren]

I'm assuming you have full control over ignition events with your engine management. With that, I'd try the OE coils and see if they are sufficient. Coil-on-plug gives a pretty strong spark as it is, might be all you need.

(just hate to see the wheel reinvented until it's been proven to be an unusable wheel)

If that doesn't suffice, I'd look into whether there are any direct swappable Toyota coil units from a boosted Toyota. (assuming they aren't exactly the same parts) When it comes to stuff like this, you simply can't beat OE reliability. (not to mention availability and price)

It may be a long shot, but the 4b11 uses a similar setu as the Yaris. They have quite a few upgrades for the EVO so they may have one that will work for you.

I have full control over ignition ande you are right in saying to try with OE coils ... will discuss this with my tuner about it

[d1nzfe]

okada are good.

[yaris 2sz]

i think so. okada

I can actually check on that today since I just bought myself a Lancer and will be selling my Yaris.

If they can't spark at higher boost levels, the engine will misfire. If it doesn't misfire at maximum boost, you don't need uprated coils and will see no benefit from them. Spend your money on something else.

[Parmas]

So I ask since now many are boosted..... can anyone post maximum boost achieved with stock coils ?

[scioncrew]

:thumbdown: not needed.. unless your going for big power. even then your going to need a CDI unit with the coils. put your money else were like tuning on the dyno.

You can share your information based on fact on what you said.....

[Yaris Hilton]

Another option to consider is reducing the plug gap if you did experience misfiring under heavy boost. I doubt you can use enough boost with 10.5:1 compression to encounter firing problems. I think you might just find it won't go quite as far wider than normal as the plug wears before it begins to misfire as it will unboosted. But I don't run boost and don't plan to.

I have seen neglected plugs in unboosted engines grow some impressively wide gaps before starting to misfire. (Including my daughter's old Echo that came with standard plugs, no platinum or iridium, and went 107,000 miles.) The stock coils have a lot of extra voltage capacity with the plugs at stock specs.

[scioncrew]

Yaris Hilton now what he is talking about.

I do have hands on experience with the AEM coils and they where not good. Garm's car went throw 5 coils,2 AEM CDI unit (with has been over a year and still have not gotten replacements) and a MSD DIS-4. Garm's car now is running M&W ignition CDI box and 4 Honda CBR coils and is bug free :thumbup:. Im sad to say I don't recommend AEM CDI or there coils to anybody any more.

Hope this help..

Can you tell me what do you mean by big power in terms of hp or boost?

My intensions for now are 14psi boost using the same turbo Garm has. Do you know if the stock coils are reliable enough for that power?

400+ hp 25+ psi thats big power for the 1nz motor. 14 psi should not be a problem with OE coils. My low boost is 14psi and high is 20 and I'm on stock coils.

Scionscrew.... did you meant the CBR600 or the CBR900 coils?

Which of them is the better or is there any other better than these?

CBR600 - http://cgi.ebay.co.uk/HONDA-CBR600-COIL-STICKS-/260617604584?cmd=ViewItem&pt=UK_Motorcycle_Parts&hash=item3cae050de8

Those both look the same to me, just one set has the connectors with them.

[scioncrew]

there all the same just deferent length but they look like the ones I have. my coil are like 5 5/8 long end to end.. get them with the connectors.

[Parmas]

I think the CBR900 coils are better since they are used on a bigger 893cc engine compared to the CBR600 599cc engine.

That's just my opinion

[Bluevitz-rs]

The same coils are used on almost all toyota's so that doesn't really say much for displacement and coils.

[Yaris Hilton]

Displacement has nothing to do with it. Just the breakdown voltage in the spark plug gap. That increases with plug gap width and the density of the fuel air mixture in the gap. Standard coils have a lot of excess voltage for normal operating conditions.

Could you tell me how you fixed the coils to the top cover due to movement.

I am noticing that the cbr coils do not have a hole to screw them fixed unlike the yaris coils

[Bluevitz-rs]

You could simply make 4 small brackets out of alluminum to hold them in place.

[scioncrew]

just make some brackets.. call Garm he made some brackets for his car. you can see them here http://www.scionlife.com/forums/showthread.php?t=186844&page=2

[scioncrew]

not sure the coils you have are long enough? that not what you showed on the e-bay links...

[Parmas]

The CBR600 coils arrived today...

There seems to be an issue, I am not liking the fact that the plug is just touching the cbr coil tip unlike the yaris coil in which it goes into a fixed spring into the coil tip.

Here are some pics....

To scioncrew... can you post some pics of garm coils to understand I have the right coils here.. Thanks

[cali yaris]

here is the picture showing the brackets we made. The top of the bracket has a little threaded "bolt" with a rubber pad that holds down the coil. one 10mm bolts ties down each bracket.

However, the CBR coils are so solidly attached to the plug, it's hard to imagine them popping off the way the AEM ones did.

[Parmas]

Can you take a picture more focused on coils?

BTW have you weigh the intake flange already?

[scioncrew]

OK it looks like you got the right one.. i will try to get some pictures up just not sure how to attach images

try removing the spark plug caps.. you will have to us spark plugs that have removable caps. here is picture http://www.yarisworld.com/forums/album.php?albumid=461&pictureid=2789

[scioncrew]

just so you know not all spark plug caps come off. it will be very obvious if the cap will come off. if you cant see threads on the cap it will not come off.

[Parmas]

I am recently installing a new engine management and I got a doubt about the coils connection terminals.

In the engine managment manual it says that the positive terminal must be common with all coils while the negative terminals must be connected with external ignitors then to ecu. The problem is that the common wire in the coils stock loom is color coded Black and White and I am suspecting that the wiring needs to be adjusted to match the my management.


Scioncrew.. since you have experience with these coils, do you know which of the terminals is negative or positive?
