Yes it will
Read an article about a gassed 4.2 that used the injection manifold, cam and dissy.
Made good power, have you considered a pirahna opticle electronic ignition? (fits where the points were)

Hi Wayne,

There are a number of aftermarket electronic ignition sources available, such as the ones mentioned above which introduce an electronic control unit into your ignition system, and replace your points with any of a few different trigger systems, such as optical, or magnetic types....

I can't speak for the performance of these units, as I've never tried them, but I built an electronic ignition kit for my '90 Maverick TB42 with a kit available form either Jaycar or Dick very well - noticeably smoother acceleration through the rev range thanks to the extended dwell angle, economy improved by a couple of lt/100kms also.....

The nice thing about the kit is that it retains the simplicity of the points as a trigger mechanism - rather than using them as a current source, they send a very low current trigger to the electronic control box - and the box does all the work. The points will last a very long time in this state, and the setting of the points is no longer critical. IF, and it is very unlikely, ....but IF the control box ever broke down with this system, the box can be bypassed back to the original points in a very short time whilst in the bush to get you home - something that an optical or hall effect sensor type of electronic ignition cannot offer......if they stuff up - your stuck :-)

if you want more info, you can email me:

I should have metioned that the kit I have described here only cost a little over $50 to build and install. Certainly a cheap option when compared to most of the commercial aftermarket installations.

hi Luke,
iam in the process of buliding the hall effects kit from jaycar , sounds like you have a good improvement over the standard system.Have you or are you thinking of adding the programable ignition kit ?It would be intresting to know if this kit would make much more of a differance.I should say i have a Ford Maverick with the tb42.The standard system had a missfire under light load but that was fixed by installing a extended rotor button.But iwanted to change from the points system so thats why im going for the jaycar kit, and being on gas the programable ignition kit might benifit the gas system.I also run upper cylinder lube which helps when on gas.
regards stephenJNQ.

G'day there Stephen,

I haven't really thought of building the programmable ignition component yet - I'd certainly be interested in seeing if it was worthwhile. I'm on gas also, so programmable timing may be a distinct advantage - at $58 I guess it might be worth trying.

What was the source for your extended rotor? I'd be happy to install one - it can only help to provide an easier path for Mr. Spark :-)

I'll be very interested to find how you like the kit with a hall effect sensor - I certainly am happy with the points trigger used with this electronic ignition, and like the peace of mind that if the control box should fail I can return the path back to the original points. Having said that though, if the hall effect provides distinct advantages, it may be worth looking at? Where are you sourcing the hall effect sensor from?

If you need any ideas for mounting the control box etc, let me know I can email pics of my setup for you....

One of the best ignition systems ever made was fited to the nissan blue bird. It is only 4 cylinder but with the rotor and cap from the Bosh comodore or similar you can get a very good set up for little money, Eric.
