Hi guys, been reading up on this as I have now bought some of these echo coil packs. I want to do this swap in mt rb20. Do I bypass the ignitor? If so how can this be done? Also is the wiring for the coils the same as rb25? 

Yes you have to bypass the igniter. It’s done by bypassing it

Hi Kraken,

I just completed this not to long ago on my RB20, what I did was identify what wire from the ECU fired what cylinder and then soldered that wire up to the corresponding plug on the loom. Another way to do this is outlined above by just pairing the numbers on the bottom of the ignition coil. But I recall there was an extra wire I had to do something with, I'm pretty sure it was a ground wire which I just paired up with the other ground wire that goes onto the coil pack holder..

Below is the colour combination of the wires for my stock ECU which may be relevant but double check yours..

Thank you very much that makes sense! Thank for the pinout will help with future guys doing the swap as well as my self!

The wire that goes to the igniter for coil 1, now needs to go straight to coil 1.  I think you can work the rest of the pattern out.

Yes great answered many questions with that.

It is hard to beat RockAuto for these, at least for quality coils -- Denso, NGK, AC Delco/Delphi. Avoid junk. Denso is a major supplier to Toyota, and Toyota had a lot to do with getting the company off the ground and is still a big minority owner.

If DENSO makes the part then it's the OEM Toyota part - so buying it from a Toyota dealer is just a DENSO part in a Toyota box with mark up. 

 

Any reason people are not running R35 Coils? They are generally considered best on the market and only cost $60/ea. 

Yaris DENSO 6731306 - $52/ea

R35 Hitachi IGC0079 - $61/ea

 

PRP has a breakdown of the two coils in comparison.

People are using R35 coils. No-one in their right mind would choose Yaris/Corolla type coils. This thread is a hangover.

If we're going to revive a thread like this we should discuss the recent drama around this article: https://www.50ignite.com/blog/technical-blog/article-3-back-to-back-testing-of-370z-coils-re-co

      Do the R32s run high or low impedance injectors?

      It may not feel like it to your wallet....but sounds like this was one of those "lucky you did it" rebuilds. Hopefully you have better luck this time

      It's aftermarket. It also reeks of Honda Civic tryhard from 2003. But if you want one....then you want one.

      Well some mostly good news and some slight bad news.  Good news is cylinder 6 did in fact only require a honing and I'm good to run my 86.5mm pistons again. I should also get the block back by end of week. Bad news, had a few surprises pop up. First, main and rod bearings were trashed. No sign of any heat damage. I knew right away what caused this... I had not packed my oil pump originally and spent a lot more time than I would have liked cranking the motor to get oil pressure. It sounded fine once started so I chucked it up to luck and forgot about it. Luckily rod and crank are fine and just need new bearings. Engine builder agreed that this was the cause.    Another surprise that carbon covered up very well that I didn't catch, something got sucked up and went through cylinder 1, 2 and 3. Luckily this was no cause for concern, just needed a bit of cleaning up. Valves look fine but he will vacuum test the head this week to confirm. I'm presuming this was something left over from welding my intercooler piping, but we'll never know. I'm going to thoroughly reclean everything.    So all in all, happy the motor is fine, and I'll get it back much sooner than expected. I'll also be taking the time to convert my WMI system over to direct port. I'll snap some pictures of that when the parts come in.

      I understand, thanks. Yeah I wouldn't want the car to tip over, I'll try and use the sills, I don't want to risk smashing the chassis rails. I ordered some rubber pucks that have a hopefully big enough slotting. If the front right gives me trouble I can always just make a wood block. I'll measure and inspect the sills closer once I actually take the car up. I hope so, but the rubber blocks I had in hand so far were pretty damn firm, if they are that hard they won't give much way. I'll let you know what happens. Angle grinding rubber isn't one of my favorite tasks. I'll probably start a build thread soon, for my own documentation and "log" as well as sharing what's going on with the car.
