How to make cheap coil on plug setup
OK, so I have had a few minutes to do some research on this. According to Spoolin Up's website, they state that they use Denso Part Number P/N 90919-02240 which a quick google search reveals is from a 2007 Toyota Rav-4, among other vehicles. The Denso part number is 673-1307.. With all this information a quick search on the Advance Auto Parts website reveals this....

Don't know if the link is going to work but the down and dirty is that the coils that SpoolinUp uses retail for 109.99... SO after purchasing four coils, you have paid out the equivalent of the SpoolinUp COP system, but you still need pigtails, wires, shrink tubing, and a plate to mount everything to.
Seems more like a whole lot of work and more money to achieve the same results. I am not saying that its pointless, if you use used coils, and different materials such as wire and mounting solutions. Honestly it doesn't seem cost efficient to me after some research..

dunno where you found a rav 4 using that coil. maybe there is but most of us seeing that coil being used on a yaris among a few others. and yes brand new they probably do cost 100 ish but most people doing this on here are buying used coils. and obviously used ones are cheaper. pigtails you can prob buy from junkyards or even spoolinup sells them. not sure if they still do.
I fried my ECU trying to DIY this. I'll admit there might have been a short circuit because the wiring was kind of dodgy. I found out that the ECU might be fried after a lot of Googling, eventually I located a thread here where someone had the same problem (one coil not firing) and someone asked them if they had a COP kit. The guy had a SpoolinUp COP kit (no dodgy wiring) and his ECU also fried, it fried a while after he took the kit off though.
This leads me to suspect that people have had their ECUs fried/know about ECUs frying from COP kits?
I was using S2000 Denso coils like the OP BTW, not the Yaris ones.
Needless to say I didn't attempt to wire up the coils after the ECU frying incident.
This is the thread that helped me troubleshoot the issue: https://www.evolutionm.net/forums/en...ot-firing.html

Yesterday I participated in a races in Volcan Panama, I'm running with my own COP setup, The most radical change I've seen is that I have about 25% more fuel economy.

Got mine built last night.I ordered the connecters from spoilinup went to a junkyard got some civic coils and pigtails.I cut a plate out of diamond plate.I found building the plate the hardest part of the whole thing.The car idles smoother and runs smoother between shifts.I like it. It also only costed me $115!
That's something my brother would do. He lives in Oregon too. 
My brother is into trucks, Ford's, Cummins, etc. He welded up a crap load of diamond plated stuff including a flat bed for his truck. He keeps wanting to get a Evo and I can see him diamond plating stuff. I think it's unique. It must be an Oregon thing
This has been one interesting thread & got me pretty excited about trying to do this mod on my car as well, until I got to the part about a few guys frying their ecu's! Looks like there is a bit of risk involved as well?? On the other hand, looks like a fair number of folks report great results too.. Regardless, it seems like a worthwhile mod!

After reading this I got motivated enough to start ordering parts.
On Route:
06 RSX typse s denso coils $73
Denso pigtails from spoolinup $28
Coil connectors from spoolinup $14
I still need wire and from what I read I need 16 ga Tefzel but just want somebody to tell me I am correct before I order some. Also What should I use for shrink wrap?After it is all wired up I just need to make a plate and miscellaneous nuts and bolts I can get locally.
