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.

Just wondering will this conversion work with stock rb20 coils with changing the dwell timing?

I'm looking at doing this conversion as my coils have shit the bed, want to upgrade but I'm unable to change dwell with my current ecu.

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
