Ignition system upgrade for the Mitsubishi EVO 8 / 9 – 4G63 engine.

Final Thoughts:

With Ignition Projects easy integration into the factory ignition system and ignition ensuring multi-spark capability, Ignition Projects coils are a high energy coil and a multi-spark box all in one to enhance modern ignition systems with no wiring or fabrication needed at all!  This is a mod anyone can do, usually in minutes.

We have previously used Ignition Projects coils (formally Okada Project) on many racing applications from drift to time attack cars with great success.  Tons of boost, Nitrous or stuff like water injection that makes the fire hard to get started, no problem!

On Project Evo IX  the Ignition Projects difference was apparent as soon as the key was turned, the engine started up much easier.  Before it would take a few cranks and cracking the throttle a little as the engine was cranking to get the car to start quickly. Now the car simply fired right up, even when stone cold.

When driving, the water injection misfire was immediately gone.  The throbbing idle is much more stable, especially when the engine is cold, no more stalling.  The engine runs much smoother in general under all conditions.

We have a lot of stuff planned to get more power for Project Evo coming up in the next few months. Getting the ignition up to snuff is the ground floor to get things going!




  1. Nice write up and looking forward to more Evo articles

    Just to add, I have done a coil on plug upgrade on a somewhat stock Evo 8 using Toyota coils and the difference in engine “smoothness” was surprising.

  2. Is the dwell time the same as factory? They look like they would bolt to my suzuki HT81S engine, but I dont have a standalone, so what should I check before switching my ignition setup with something else? I have heard of damaged ecus from switching to different spec coils, but nothing concrete.

    1. Since we are only switching things on the coil side the dwell time is the same. You can damage your ECU if your coil impedance is way different but in this case, the IP coils are application specific and they will not hurt your ECU.

    1. That looks like a pretty good system using the Honda pencil coils but it doesn’t have the multi-spark capability of the IP coils.
