Hi, I have read through and followed the http://atlanticz.ca/zclub/techtips/distributor/index.html instructions numerous times for upgrading the distributor to a 280zx on a 240z and have not been able to get my tach to work at all. I have a 3 ohm coil, 280zx distributor and the car is an 11/70 240z (note that the majority of the instructions are for a 280z). I have spliced the blue/white and the green/white wires together from the harness. The thick black/white tach wire is to the postitive side of the coil and the black wire is to the negative. The black wire from the harness is to the distributor box and there is a new wire going from the positive end of the coil to the distributor box as well. Pictures attached so you can see what I did. What happens to the orange(yellow?) lead from the harness? Did I miss something or can someone weigh in on why my tach isn't working?
Alright guys so I was planning on using a Mallory MAL 2363901 distributor and pertronix in my 11/70 240z but I just got an email back saying that they're discontinued and sold out. Every other place I've tried online seems to be sold out as well. I'm thinking of going with the Mallory unilite with mechanical advance (no vacuum advance) coupled with pertronix and was hoping someone else here might have had success with it and can give me some info. I'm going to be installing triple mikuni carbs shortly and plan on keeping the ballast resistor and using a 1.5ohm coil as well. If someone has done this before and could share what model they are using it would be greatly appreciated! As a side note, I have looked into other options such as late model distributors and have decided that I want to go with a Mallory one and spend a little bit more. Thank you. Chris
I am in information overload here and I am looking for setups that have worked for others. I have searched and searched and with all the info out there on all the Z sites I can't determine what actually worked under what circumstances. I mean seriously, you can prove and then disprove the theory of relativity within a post or two in some of these threads. The short of it is that I am in the process of connecting an MSD 6AL with MSD Coil to a 280ZX Distrubutor in a '72 240Z with the original tachometer. The more complete version: I recently picked up a somewhat used Rebello 3.2L with triple Mikunis and have already put it in place... along with replacing the entire driveline... ACT Clutch, T-5, STi R180 LSD, Wolf Creek Halfshafts. The ZX ignition module was not being used in the previous owners setup and it was running the MSD instead. The wiring for the MSD seems pretty straight forward... because there isn't a module the green/purple goes straight to the dizzy which is wired for it. The coil is straight forward. I "think" I need the 8920 Tach Adapter... but in a thread somewhere somebody was swearing up and down they were using the 8910... and then there is the 8910EIS. And in a few spots people are saying 8610, which MUST be a typo because that's CSB crank trigger kit. I'm pretty certain I will need one, but which? I remove the ballast right? Where do those wires end up? Aren't they going to the tach? Is this where the Adapter comes into play? Also, what is this about the ignition signal running through the Tach and if a wire somewhere is disconnected it won't start? I plan to connect the MSD up tomorrow and fire this baby up with or without the Tach, I just want to know that a solution is on the way. I've actually got a brand new Mallory Uni Lite in a box that will eventually find it's way on this motor, but I want to prove the engine works in this car with it's last known good setup before I start swapping parts. Thanks!
