I think hes talking about the Jaycar HEI conversion kit. I havent tried one personally but I mean to soon. They have been covered before in the forum so a jaycar search will yield results. They use the points as a switch instead running voltage straight from the coil stopping them arching over time. I still reckon that you need a hall sensor fitted to stop points bounce. Any takers??

dick smith used to make a simple HEI ignition system that used your points as a low voltage switch and then drove your coil to produce good/fat sparks, regardless of engine speed and (to a lesser degree) battery voltage.
it made points last for ages as they were only switching a few hundred miliamps and were no longer arcing (the cause of points wear and settings changing).
kit used to cost $20-30. i had one in my old RA23 and i never had to buy points or reset the points thereafter.
nowadays, DSE and jaycar sell more complicated HEI/CDI systems but they're able to deal with a variety of contactless points (Hall effect, optical, reluctor, etc).
you could also get the roter, switch, coil and igniter from a compatible toyota dizzi.
is worth it - easier starts regardless of weather, good sparks thru the whole rpm range, less maintenance.

i stand corrected then  .. is yours designed for electronic ignition? if so, it should be able to handle the increased dwell time.
both the compact and the oil filled orange GT40 coils i have had have died quick deaths...
the echlin points type oil filled coil i had lasted a number of years.. then it died suddenly with no warning.
now i have a toyota oil filled coil that is designed for electronic ignition (from US starlet?) and it seems fine also..

Thanks for the info guys.
I spoke with my mate yesteday and he still has the kit he made up for his escorts, I think I am going to try that, and then maybe look at the Jaycar kit you posted a link to.
I had thought of trying to do the transplant of an electronic distributor into the ta22 housing, but I don't know which car to get one from that has the bits I would need.
The kit will do for now though

Hey,
re: just need a 2tgeu dizzy (EFI 2tg)
So all I need to do is find one of those and it will go into the 2T block directly or do I take the guts of it and put it into the 2T dizzy?
(also need the 12v coil and that would be it right?)
Thanks.

Ahh ok, cool, I will keep an eye out for one.
Meanwhile I put the kit that my friend had made up for the escort into the TA22, seems quite good. the spark on cylinder 1 was visibly brighter when the kit was in the on position. (although i had just cleaned and set the points before I did this kit.) Previously I checked the spark with the points before I cleaned it, so It may have been that too.)
Anyway what I did do is check the voltage going to the points when the kit is set to On, around 7-8v (slight fluctuation), when the kit is off it was reading 12V.
It did seem to be a bit more responsive when driving, (less hesitation on putting the foot down), but then that could just be the placebo effect too, me wanting it to feel smoother
Thanks for all the info guys, got some more ammunition to play around with now.

becuase the points are no longer switching large amounts of current, you'll find they stay correctly adjusted for much longer time - you'll probably not have to buy another set in the life of the motor. The only earing thing is now the finger that follows the cam on the rotor shaft - as long as it gets grease occaisionally it'll remain intact for ages.
