Re: Tookwik's 7M C.O.P. ignition mod w/ stock electronics...pics and writeup

I've been running these since before this thread existed. Ive never had sputter due to the swap. The only time I get sputter now is when I hit 17psi... But thats because I'm running ungapped Denso Iridiums for the Honda v6 j30a4. My old iridiums were fouled and this was all I had laying around and I cant gap them... So they are at 0.048"

Lots of guys on the IS forums seem to do fine up to 600rwhp. I've pushed mine over 400rwhp and thanks to my crappy wastegate spiked to 22psi i.e. possibly 450+. I may also sell mine and return to stock since they still work and I'm needing to fund my 1jz Cressy build.

you can't. the coils sit down in the valley. if you want to keep crap from falling down there, make a cover the goes over the top.

Re: Tookwik's 7M C.O.P. ignition mod w/ stock electronics...pics and writeup

Just picked up 3 coils for $70 shipped.
Looking forward to trying this mod out. I see that Flubyux is using a plug gapped at .048", with no breakup at 17psi. This tells me that another benefit to this mod might simply be more efficient combustion @ idle/part throttle, due to that increased gap. Am I over-assuming here, or if this is the case, wouldn't that suggest a slight improvement to mileage?

You won't get an improvement in milage or power unless your current set up is not good enough and you had slight misfire. It shows up on a dyno and even better with a 4 or 5 gas analyzer.

Re: Tookwik's 7M C.O.P. ignition mod w/ stock electronics...pics and writeup

Well, I do have a slight miss at idle.
Not sure if it's the same as everyone else that's reported a miss; it's like one micro-miss every
3 or 4 seconds, hardly noticeable, actually. And I have done the igniter ground mod.

I have the same miss. Sometimes worse than others. I have also done the igniter ground mod with this upgrade and I still have the miss. Im pretty sure its the igniter set up with this engine. Guess I will never know unless I go stand alone.

Or you trimed the airflow meter signal to raise overboost fuel cut.

Great writeup, about to do this mod to my NA-T 2jz that runs on 7M electronics. I have a couple of extra sets of the IS300 coils I'll sell if anyone is interested, just PM me...

Re: Tookwik's 7M C.O.P. ignition mod w/ stock electronics...pics and writeup

Okay. I just finished reading through this whole thread. Love Tookwik's setup. I'm a bit surprised that nobody asked what happens to the little white ground wire (I assume it's a ground) that goes from one of the fuel rail mounts to the 7M coil pack plate. Didn't even see it in any pictures.

I just ordered some NGK ones, the look to be the same size wire core but I will give a review once they arrive this week for those interested :)

So I have my coils mounted and when I went to remove the plugs from the original coil packs every fkn one of them broke. The wires are cracked and generally just junk. I saw somewhere that someone was making the harness for a decent price. This still happening?

Re: Tookwik's 7M C.O.P. ignition mod w/ stock electronics...pics and writeup

Yes.....thats it. IS300 coils, plugs, and the 7M coil pack harness that needs to be extend to reach the coil on #6 and #3. I believe the coil that sits on #2 is close enough to the wiring harness connection. This will be one of my first mods when i have all the little bugs fixed on my 88 supra.

Re: Tookwik's 7M C.O.P. ignition mod w/ stock electronics...pics and writeup

just did this mod because my stock coils cracked, is300 coils worked great and running strong @ 18psi.

Re: Tookwik's 7M C.O.P. ignition mod w/ stock electronics...pics and writeup

Okay, so I have read through this thread and I love every bit of it.
Absolutely can not wait to do this. Nice clean look instead of big coil packs and what not



Now i do have one question though..And I have read every post in here, but my head hurts so i probably missed it.

When doing this mod everything is pretty much plug and play which is awesome. I couldn't help but wonder though..What did you do for the little ground wire? The wire that you tighten down onto the coil pack for the ground.

I'm sorry if I missed it or it's a very easy answer, just can't wrap my head around how it is grounded.

Thanks!


Edit: Hurp durp, just saw Mikesfixedroof had already asked this question on the previous page hah

However, the question still remains

The is300 coils don't have that little ground wire (or at least mine didn't). Maybe someone else can confirm.

He's speaking of the stock setup and the ground wire from the bracket that holds the coil packs to the head.

That is correct poodles ^


I'm just curious. Everything about this mod is straight forward and seems simple enough. The only thing that throws me off is what to do with the ground wire

Well, if yoo do some kind of hold down for the coils, they'll be grounded that way. The only reason that ground strap is needed for the stock setup is because the coils aren't rigidly mounted and instead use rubber insulators.

Re: Tookwik's 7M C.O.P. ignition mod w/ stock electronics...pics and writeup

I guess I'm still confused, but my is300 coils don't have anywhere to ground too. There is the connector for the wiring harness, the secondary spark plug wire connector, and the spark plug connector on the bottom. There is no exposed metal to ground, they are a sealed plastic casing.

Re: Tookwik's 7M C.O.P. ignition mod w/ stock electronics...pics and writeup

So if I am assuming correctly...you simply just don't need the ground wire then?
