ej20G coil conversion - Page 11

JDMFLCL · 02-27-2010, 01:27 AM

So, If I am tuning for around 17-18 lbs of boost, I want to go to BK7re?

^ BKR7E not BKR7RE

DeusExMachina · 04-25-2010, 04:55 PM

I'm having tons of problems.

We (JDMFLCL+Me) wired everything exactly as the thread instructions described. When I turn the key to ignition, all of the solenoids are clicking, pump primes, but I don't get any spark.

Help!\\

1995 EJ20G with 2002 coilpacks

dr3w · 04-25-2010, 05:27 PM

^ Go see my post on page 10 about the igniter ground. On robs the ground pin was in the center (third pin) mine was the first pin so you might have soldered that ground pin to a coil and left the proper wire hanging.

It seems Subaru used two different EJ20G igniters one being the one you see on the first page and the one i have and they have different ground placement.

Rob's EJ20G Igniter with Center ground (3rd Pin) (Believe this to be 94+)

My EJ20G Igniter with ground off to the side (1st Pin) (Believe this to be only 93)

JDMFLCL · 04-25-2010, 05:30 PM

Its the same as Robs in the middle. Could I call you?

Send me photo's of everything you did for now and ill try to spot the problem because if all 4 are not firing its just probably a small something you looked over.

JDMFLCL · 04-25-2010, 06:06 PM

We've basically come down the conclusion its not related to the ignition. When the car is put into on with the key, it starts flickering right then.

DeusExMachina · 04-27-2010, 01:30 PM

It was his dumb battery. It decided to die while we were making a major change to his ignition system. Jumped him off my car and it fired right up. He got a new battery and its working great AFAIK.

I've only seen that ignitor on Legacy Ej20Gs. It would likely be a one year only thing, like you say, if it was used on WRX Ej20gs. I've owned several '94's and a bunch of '95 and '96 swaps. Never seen that metal ignitor on any of them.

Does your wiring have white dashes all over it?

I wouldn't be able to tell you i heatshrunk/tucked all that wiring while doing my conversion it would be hard to get to.

But ya i was surprised by it when i first saw it and then when i also realized the wiring was different.. had no clue legacy's where the same way so basically all WRX/Legacy 93 EJ20G's used them i guess.

Would love to know the reasons behind why they only used them one year though.

ThermosMcJug · 05-21-2010, 06:05 PM

Another satisfied customer.. My wagon is running 1 bar at .030 gapped BKR6ES plugs... Where there was major missing, there is now none. Also managed to get the connetors from my local wrecking yard for a song so no nasty spades , just solder and heatshrink.

efeight · 05-26-2010, 09:19 PM

x2 ^ i could only find sti coils they are a tiny bit shorter as far as boots go, so i had to stretch out the lil springs inside.

but im running 1.0bar cleanly!

thanks to the original poster!

Vertical_Lab · 07-20-2010, 07:13 AM

Does a 97 Ver 3 GC8 wrx comes with the ignitor?cos i cant find it anywhere?

dr3w · 07-20-2010, 07:51 AM

^ um you don't have coil on plugs so this thread doesn't apply to you unless you did like me and run the stock EJ20G electronics on an EJ20K.

FYI, my 93 WRX has the same metal ignitor.

drummersrs · 09-14-2010, 08:06 PM

Just completed my coil conversion......... excellent write up Rob. Again anyone who has an ej20g must do this!!!!!!!!!!!!!!!

dr3w · 09-18-2010, 05:18 PM

Just a reminder since i get asked this so often.

If you have a metal igniter(1993) your ground is on Pin 1, if your igniter is plastic(94+) your ground pin will be like rob mentioned Pin 3.

See post #254

I think the ambiguous bit is that despite the pin location, the color combination remains as Rob says. I just finished this today on my '93 and solved 100% of my misfires, hesitation and backfiring. Discovered that just one of my coils had a crack in it.

Rob - nice work! This is a fantastic tip and a super easy fix.

FYI, I found that I didn't have to lever my engine at all. Simply turning the coil upside down and inserting allowed it to get in the head, then flipped it right-side up. Super easy.

------

Update: apparently I magically possess another issue. I think the coil issue was compounding another one. Still have intermittent missing, but not as much of an effect as before with the old coils. Also have some backfires as well.

daigle46 · 09-21-2010, 08:22 PM

hey yeah so i just finished doing this conversion on a 1993 wrx with 2004 sti coils and now i get no signal to my coils... my igniter doesnt look exactly like the one in the picture but has the same wiring... has anyone with an early model wrx do this conversion and have it running well cuz my doesnt start at all....

help please!!

I did that just last weekend. Does yours have the metal ignitor? Mine did and I found that the wire colors matched exactly as Rob had stated (though the position is not the same on the metal version).

One thing that was confusing (sorry Rob) is that the pictures don't exactly match. You have to follow the instructions and use the "top" coil picture for proper pin wiring.

hksw20 · 11-13-2010, 03:10 AM

Had someone try to do this on the car I just picked up, good to have some reference so I actually understand what was done. Just curious tho, does anyone know what the ECU signal sends to the igniter (or coils now)? I have no spark and the ignition output wires are grounded with the key off (both at the ecu and where they would have gone into the igniter), and with the key on they jump to .05 V. Sound normal?

DeusExMachina · 11-13-2010, 09:52 AM

I did this on a friend's car. The coils have power/ground/signal. The ECU just sends a small voltage to the coil and they fire. Sort of like a relay.

If the signal from the ECU is that small voltage, it sounds normal. Check the power and grounds.

The ECU sends 5v pulses to the igniters. I don't think a simple key on voltage check will tell you anything useful. I would start by going through the wiring and verifying it's connected as shown on page 1. Then verify 12V and ground at each coil. After that you can pull a plug, touch the threads to ground and watch for spark while someone turns it over.

acidbottles · 11-30-2010, 09:38 AM

would anyone have or know where I would be able to get my hands on four newage coil connectors with pigtails?
looking to do this conversion and it sounds like a much neater way to do it.
thanks

spackyscooby · 12-01-2010, 07:45 PM

Ok so I have some questions. I have a 96 v2 sti in my car but when the swap was done the 2000 rs coil pack (with the built in ignitor) was used and apparently the plug wires are custom using the dohc plug boots and the proper boots for the pack. What I am wondering is if this conversion could be benificial and what I would need to do differantly since I have no seperate ignitor? I am curious due to the fact that the coilpack is only secured by one bolt and as such has the ability to bounce around which just doesn't seem right to me and also the special plug wires make it kind of a pain when it time to change them. Any help/suggestions would be greatly apprerciated.
