Konish Posted May 1, 2010 Share Posted May 1, 2010 I searched here and on classiczcars and found answers, but not in the combination I'm looking for. I have a '71 240z that has a 280ZX electronic distributor installed. The ballast has been removed and the wiring has been modified to use the stock 1971 240z tach. I have been having crazy misfires when the car gets warm. I can clearly see this happening on my Innovate LM-2 wideband. In the morning, I get a steady AFR with a few hiccups and as I drive it the idle AFRs are *all over* the place. A new coil is on the way but I have a sneaking suspicion that it's not going to solve my problem. I know this much about the installed distributor having taken it apart. Most of the breaker plate guts are missing (bearings, retainer plates etc), basically there's just enough of the breaker plate stuff left to screw the thing back together...which doesn't matter as I'm not using my vacuum advance. I also can see that one of the reluctor teeth is broken (increasing the gap 3X larger than the other 5), but the stator and magnet are fine. So, instead of buying all the little parts and maybe the ignition box etc, I was thinking about gutting the distributor and dropping a pertronix or crane ignition system. Since my wiring has been modified and the ballast removed, will this be an issue using either? I know they were designed to replace the points in a dist., keeping the ballast and everything else stock (?) Any other recommendations? If nothing else, I gues I can bit the bullet and buy a high performance Kameari dist or Mallory Unilite, but that's some major coin I'd like to avoid for a street driven, slightly modified motor. Thanks! R/ Dustin Quote Link to comment Share on other sites More sharing options...
BunnySlippers Posted June 9, 2010 Share Posted June 9, 2010 Check out these two links. They should cover everything for getting the ZX unit to work properly, just incase you don't upgrade. http://www.atlanticz.ca/zclub/techtips/distributor/index.html http://www.atlanticz.ca/zclub/techtips/distributorrebuild/index.html Also, I'm pretty sure the modifications made to use the ZX dizzy are the same ones required to use the petronix or crane unit. I'd recommend either rebuilding the dizzy you have, or pulling one from a junkyard. They work great when all the components are intact.
