OK fellas, I know not everyone cares about modifying things like this just for asthetics. If I had to pick a side, I would be with the function group rather than the form......but I'm not the guy that thinks you have to pick one or the other.

I've been wanting to figure this out for quite some time. Last year, I was planning to make it happen with 1JZ or 2JZ coils. After alot of searching , I found that BigAaron was already in the process and it wasn't working with the factory ignitor. He finally beat the system and made it work, but it took 2 ignitors, and a circuit board that Aaron designed for it. I believe it was just more complication than it was worth, and he came up with a mod to move the coils under the intake.....which is great, but not for me with the RonR short runner. I was bummed and didn't give it much thought for a while since it just didn't seem like it would work with our waste fire setup without a stand alone.

Then one day, about a month ago, it hit me while I was doing a tune up on a 97 Tercel of all cars. Toyota made several cars in the late 90's and up with COP and a waste fire. So I started trying coils from everything I could find.....Camry, Avalon, 4runner, Tercel, so on. Everthing was too tall, they all have spark plug tubes. I posted a want ad for some 1J or 2J coils, thinking i could use the shorter tubes on the waste fire coils. In the meantime, while searching the web, I found that the Lexus 2J's had a waste fire C.O.P. that was short. Come to find out one model of Supra has it also, the 98 N/A with vvti. BINGO!!

I picked up a set of low mile used coils off ebay from an IS300 and ordered a set of new wires from the 98 Supra N/A through work.

Here is what the IS300 coil looks like...



Here is a pic of them in the head without wiring...I will make some 6mm studs for them to bolt down. I will drill just a little bit into the oil galley plug, enough to catch a thread or two and epoxy them in, or maybe find a better way with a small bracket. They don't need much to hold them down as they sit pretty nicely in place as it is.



I made a new harness for these, I got anal as usual and resoldered the pins at the connector, and replaced the connectors on the coil end. It's a fairly simple but time consuming process.


Here's all the parts neccesary to make it happen, pretty simple mod now that we know what we're looking for!!




I drove the car about 10 miles, achieving 20psi and over 6,000 RPM's with no breakup. I won't be driving the car much in the next couple months as I'm tearing it down for body work. If any of you tech experts see a reason why it wont last or might fail in time, please speak up. Primary coil specs on ours and these are pretty much equal. I browsed IS300.net and found members are running turbo cars up to high 20's boost and 550-650 HP on the factory IS300 coils. Since I've already crossed the 600 flywheel HP mark, I will probably run an HKS DLI and try finding some high performance wires for these....which I haven't found yet, if anyone knows of some...please speak up.

Here is a quick vid of the Red Rocket running on the setup...


Finally, the bling.....I will polish this cover I made for mine now that I know the setup works!:icon_razz

Ignition System.....what....where:biglaugh: :love:




EDIT.....I am adding pics of coils installed with the brackets, I shaved a little off the coil that sits on #6, so it sits in nice and straight, the one on the left I trimmed and thats the bracket...it bolts into the threaded hole on the rear plug in the head.

Here it is installed....

This is the bracket for the other 2, they sit on top of #2&3 plugs. The plug in the head between them is not threaded, so I took the rear one from a spare head.

Here they are installed....

And this is the complete setup installed waiting for the cover to be completed....

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

Nice going 2quick ;) Looks like you have your answer already... The car isn't breaking up at all right? and at high boost etc? Can you log timing? See if it actually has any breaks in the curves. again, it sounds like it is already working for you though.

Nice install

I got pm already :biglaugh: Very nice! I like it a lot, it gets rid of the coilpack and doesn't require additional electronics. +1 to you!

that is one sweet setup bro.
So just to get this straight, because i'm not too familiar with this approach.
You put the coils on 3 of the sparkplugs, then the sparkplug wires off each coil goes into the remaining 3 sparkplugs?

Exactly....you just have to make a longer harness, and find a way to secure the new coilpacks.

First off, I just want to say that's great you finally did something about that damn coil pack. I LOVE your engine bay and have always hoped that you were going to do something with that big old thing soon!

I read a little fast, but I didn't see how much you spent on everything? Did I miss it or did you not post.

LMAO....thanks! I have a new p/s res too, thats the next eyesore to go.

I'm going to get some prices on parts tomorrow, if you buy new coils, that will be the expensive part, if we can source a supply of good used ones, that helps. I will offer a do it yourself kit, maybe harness. I'm giving info to Aaron for those that want it made up for you. Maybe Aaron or Jon can come up with a sweet cover. I made mine by hand and for the time I spend on it, you wont want to pay me. Need someone to take my idea to cad, pump out some covers and give me a nice shiny aluminum one:) the one I made is stainless.

I'd like to see a couple people run around with the setup and rack some miles on it to make sure it holds out, but I cant really see why it won't. Just dont wanna go crazy selling stuff and find problems.

wow, this is good news. i myself was looking into this slowly. so it has to come from any 2jz n/a vvti , is300 or supra. and you just had to lenghten the wire harness! sweet. i will definetly follow this post.i put the ramirez short manifold as well, and those coilpacks where really, really bothering me!!!:icon_razz nice , nice work!!

As always I follow a gay joke post!!! Thanks for the PM Ken I am glad it worked out for you and for all of us. Ken told me about this in a PM when he was working on it and he was really excited that he might have this figured out. This is a huge step I think for the 7M guys to get rid of the fugly coil pack. Way to go Ken!!! :icon_bigg

Oh on a side note the Red Rocket sounds great!!!:icon_bigg



All Hail Ken!!!!

It would be neat to have somethign with 7M-GTE cut out of it, assuming someone makes it in CAD. That would be neat. I've always wanted to make something that will make the entire top of the engine more streamline.



What would change over time? I mean if it works now, wouldn't it work later, assuming a part doesn't fail?

I don't anticipate any problems with it, In fact I'd bet on it. I think I'm going to run a DLI on it, or DIS-4, but I've read up on it and it seems the HKS unit has been more reliable. I'll run it on the 1/4 mile this spring and see how it does.

I'm excited about this man. I'm going to be doing a FFIM soon as well and I wasn't sure what I was going to do with the stock coil setup.

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

I'm copying part of this reply I wrote to Larry_A in the same thread I ran on SF because I know I have dicussed this miss with several of you guys when we were first setting up maft pro, dont remember everyone that also had it, but ChrisO i'm pretty sure was one, maybe Mike Malloy.

"I failed to mention it in the threads but mine also had the "bump" miss at idle, If thats what you mean, and I didn't notice it at all after the swap. In fact I just went outside and started it, let it idle for about 20 minutes after reading your post......nothing ....smooth.....awesome, that has been bugging the hell out of me for the longest time, and I always thought it was air/fuel related. "

In fact it was bugging me this morning when it was doing it before I swapped the coils.

I'm going to throw the setup on my DD for awhile and drive around with it, maybe tomorrow or Tuesday.

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

im working at a sheetmetal company, and was planning to get some of my own parts CNC punched out of 14ga aluminum. if you guys are interested, i can make some covers... im only there until the end of march though, so its gotta be quick.

something like this (quick drawing in Solidworks, obviosuly doesnt match the valvecovers, but gives you the idea):


also, the P/N for the coils is F3000-131175, list at around $123 new, and the wires are F1020-138958, list at around $41

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

What would it cost to get those done? I used the four bolt holes from the stock coil pack and one bolt in the rear center where the heater hose bracket used to bolt into the rear most oil galley plug. Do you have a head with valve covers on it you can use to get it fitted right?

Oops, missed this until now. That is nice work. From what I've seen on how you did this there shouldn't be any problems with it at all. In theory it's electrically sound and compatible with the stock TCCS. Looks good too. Nice job.

my valvecovers are smoothed, but i might be able to get a pair from the junkyard to measure. my engine is going back together now, so measuring them on the car wont be hard. cant tell you a price, not sure how much ill get charged. im getting a 48"x120" sheet of 14ga anyways, so adding a few of these covers wouldnt be hard.

Cool, PM me when you get some info on it...and thanks.


JJ.....thanks, I was hoping to hear comments from you and JDub.....I knew if there was something I overlooked, you guys would probably pick it up.

If you guys want to clean this and sticky in FAQ, feel free when you're ready.

Ken,
That is some awesome research and development !!! I still have the random miss at idle. I don't even really notice it anymore, just kind of accepted it. I have too many irons in the fire right now but will certainly try your new setup maybe by summertime.
Again, I appreciate your time and input on this issue.
Chris

Perfect example of persistence pays off...you found a very simple, elegant solution for cleaning up the engine bay.
The best part is it works well (I can't see any reason it wouldn't) and looks really good ;)

Nicely done!

This is huge guys, Congrats Tookwik, you are soon to become immortalized in the MKIII world :drink1: "The Tookwik MOD", Now you should get with the other supra Gurus as you have already started doing, so you guys can come up with a standard wiring, a standard way to secure the coils etc. I hope to see a kit available soon.

Thanks again

I just want to say im VERY impressed with this. This can be done for under $200 with very little wiring work it seems.

GREAT job man.

I'm really impressed by this. Way to innovate man! It's always nice to see something new and well thought out for our cars.

BTW - My only negative comment would be that you need to vent that coil cover. We've had coilpack overheating problems on the 2JZ's in the past when people were using those big bling billet covers that were not vented.

All of the ones sold these days are vented, and that's the reason for it.

Looks awesome though.

I had a little discussion on this on SF, and I plan to have some vents before final install....good catch. Maybe some one can come up with a plate like this with vents, maybe even vents in the form of letters so it could say "7MGTE, SUPRA, TOYOTA", or whatever. I made this one by hand so its still in the rough stage.

Thanks for the kind words everyone. I have a solution for bolting them down, hopefully I will make it up tomorrow and get some pics. Pretty busy at work today.

Also, if I didn't mention it in this thread, and you didn't notice in pics, you have to remove the cover in between the valve covers in order for the coils to fit. I don't run one anyways, mainly because I like to be able to see that my valley is free of oil and debris.

Nice f'n work man!

I was working with a 99 (I think) 4-runner at the beginning of last week.
The 3VZ has similar coils and is distributed waste-spark like that.
Shame I never thought about it working on a 7M.



I agree with Mike... Louvers would be ftw!

I think something like this would be BADASS.

Sorry for the horrible drawing, I'm at my parents place with no Adobe.


Obviously the lines are vents, and I think having the 7mgte cut out where I marked with an anadized(red, blue, black, whatever) plate under it would look perfect.
