Good Day everyone! I just want to share this to everyone.
Recently, I had been occupying my time with rigging my Terrano with an electronic Ignition system. In case some of you don't know, the Z24 engine has been installed with the very "old-school" contact point type system by Nissan. I dont know exactly the reason for it...could be because its a very "water-proof" system...due to cost cutting...or simply neglect from the engineering department of Nissan. The fact of the matter is, this system is flawed in many ways - that's why almost none of the carmakers use them anymore. When installed properly and run at low engine speeds, it can trigger the ignition(coil and spark plug) flawlessly. The problems occur during high engine speeds and/or long term use. I think most of us who owns this type of ignition and do our own maintenance encountered the dreaded "bulutong". This flaw not only reduces engine power, but also decreases fuel economy. This electronic ignition eliminates this factor...thus creating clean and consistent sparks all the time.

Now, there are aftermarket Ignition systems available out there. Different brands like Mallory, MSD 6A & Ultra sell units that perform these things. These are decent units and will work fine with our rigs however, the price tag attached to these are a tad expensive...with some units costing more than 10k! Actually, the reason that drove me to make this is I originally planned to acquire an Ultra Ignition module for my rig. Problem is, the price of the unit increased from when I started planning to have it installed...to an amount that is beyond my own justification(in other words, kuripot kasi ako)...Anyway...

The unit that I made was based on the "electronic enthusiasts" volume 4 book, which can be acquired at Alexan... however, there are lots of other designs out there where you can choose from. The links below can give you ideas on it.

As a matter of fact, Alexan used to sell these as "kits" a decade ago. Unfortunately, they don't sell the kit anymore but they do sell most of the parts we need. You just need a PCBoard where you can solder all the parts together. You can make your own PCB (click the link below on how to make your own)
Make PCBs at home with magazine paper and your laser printer

OR

have it made for you. I was able to scrap a PCB from an old kit but I also had one made from JD Labs which cost me P600 since I only had one printed. They charge less if you order 3 or more PCBs.

After buying all the parts, you can solder them unto your PCB or have someone with knowledge in the field do it for you.


Also, wire the harness properly


Make sure to solder ALL parts in the proper order or you'll fry the diodes(don't worry, a diode costs only P2.50 so you can always purchase extra)


Almost finished unit.


All done.


Install it in an area inside the engine bay where it won't get wet. I'll post a photo of it installed on my rig for your reference.

All in all, the whole project only cost me less than 1,2k. Not bad for an Electronic Ignition module!

I would suggest you try to purchase the "Electronic Enthusiast" volume 4 book since it is more details than the other designs. Also, this module has a 1.5ms spark timer...meaning the coil only produces a 1.5ms spark - giving it enough time to recharge thus creating high voltage sparks everytime.

Since I installed the unit, I felt an increase in power, consistent engine revs, good idle...when it comes to fuel economy, I will not comment yet on an exact figure since I am still double checking the mileage gained...but over all, I felt it can help save on petrol (since the power is maximized)


If you are into electronics stuff, then this project will be very easy for you.
You can also have someone do this for you...

If you need PCB's for these, then PM me so I can help you get in touch with JD Labs.
