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....

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.
