Ignition system upgrade for the Mitsubishi EVO 8 / 9 – 4G63 engine.Posted on August 7, 2018September 19, 2019byMike KojimaAfter removing the 4 bolts holding it down, lift the coil cover out of the way.Now remove the 3 10mm bolts holding each of the factory coils in place.Remove the primary wire boot the sends power to the adjacent cylinders spark plug.Now remove the plug that supplies 12 volts to the coil and sends the triggering signal from the ECU to the coil.Now the coils can be removed.Next, remove the boots from the stock coils, you do this by twisting and pulling at the same time, the boot will pop right off.Push the boot onto the Ignition Projects coils giving it a slight twist until they snap into place.RelatedPrevious page 1 2 3 4 5Next pageRelated TopicsEngineElectricalMitsubishiEvoIgnition Projects Previous Article SC300ProjectsLexusProject SC300 Road Racer: Part 19 – Achieving Release, Mounting ProblemsPosted on August 6, 2018October 9, 2018byErik JacobsView Post Next Article UncategorizedProAm Drifters Compete for their FD PRO2 Licenses at Rd. 2 of The Drift LeaguePosted on August 9, 2018August 9, 2018byRathyna GomerView Post 8 commentsNice write up and looking forward to more Evo articlesJust 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.ReplyHow did you trigger the coils?ReplyIs 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.ReplySince 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.ReplyThat is very useful information, thank you Mr Kojima.ReplyMike,Why didn’t you choose the Spoolinup COP 4 coil setup? Did you know about it before choosing the IP? http://www.spoolinup.com/New-Coil-COP_p_22.htmlThanks for the article. 2006 Evo IXReplyMike,Why didn’t you go with the 4 coil pack from Spoolinup?http://www.spoolinup.com/New-Coil-COP_p_22.htmlThomas Reynolds ’06 Evo IXReplyThat looks like a pretty good system using the Honda pencil coils but it doesn’t have the multi-spark capability of the IP coils.ReplyLeave a Reply Cancel replyYour email address will not be published.
