Default Help! EJ22-EJ25!

Okay, Original Car 1999 subaru legacy EJ22 Brighton.

Swapped in 1997 Phase 1 DOHC EJ25 from a leggie GT.

Engine is swapped in and complete, We are not getting spark.

We believe it to be incorrect wiring of EJ22 to EJ25 Coil packs.

The EJ22 harness has 4 wires for the original coil pack, Black, Red-black, yellow-black and blue.

The EJ25 Coil pack uses 3 wires, Blue, Red-white and yellow.

How do i convert the EJ22 harness to use the EJ25 coil pack on an EJ25 engine?

thanks!

The 1999 uses an integral ignitor that is built into the coilpack. That's what you are missing. You've got no ignitor.

One thing you can do is look into a set of Kinsborne sparkplug wires. They have an application that fits your 99 coil and has DOHC boots at the other end.

I've used plain ole 180* (straight) booted Accell wires on DOH motors too. Reused the OEM coil boots with new terminals inside and never had any issues once I got the boots slid over 8mm wire.

A last resort would be to add an external igniter and do the appropriate wiring involved with it.

I'm sure you can make a bracket to hold the coil, so I won't address it.

To wire up an igniter (which you won't need if you make brackets to hold your old coil) you'll need to Splice it inline with the 2 channels of ignition you've got coming from the ECU and provide a ground. I don't have wiring diagrams with me at the moment, so I can't comment of specific wire colors. I believe it is member "Amigerslives" (spelling might be wrong) that posted up info on eliminating the igniter to run a new style coil with older style wiring harness. He's built his car from scratch, using Subaru power. If you search around the conversions forums for those terms, you may find the thread. I can look later when I get home.

If you are going to continue to do these weird mix and match swaps, which seem to give you no end of trouble with sensors and wiring, I would strongly suggest you get your hands on a set of wiring diagrams for all of the cars you intend to mess with.

The thread relating to bypassing the factory igniter is here: http://forums.nasioc.com/forums/show....php?t=1552376 you can do the opposite, by adding the igniter.

I think that is your best bet. Kingsbourne(sp?) wires has a PN for hybrid Subies, I don't recall what the number is.....but get in touch with them.

FWIW.....I mounted a coilpack to the pitchmount on the RS. Used a couple pieces of aluminum angle stock and it's been rock solid. It required longer plug wires, but it wasn't a big deal for me. Here's a couple pics. Sorry I don't have any showing the boots going into the heads, or a close up of the coil mount.....It was kind of an afterthought at 2-3am prior to a race......

At least you're making headway. I'm sure that with some persistance and patience, you'll get it sorted out!
