@Yarb I used the recommended Bosch Red coil 1.8ohm 0221119031

This should the stock configuration with a little more timing up top.

I played with the timing more today it smoothes out more on this tune. It does seem to be 2 degree retard in reality so I'm going to check tdc mark for the 4 time. And re zero the dizzy. Example: set steady 10 degrees read 8 steady 14 read 12 with the gun

Madkaw I did add the extra 10 degrees but the kpa is the same as the chart. So your saying I should do more like 8-4-0 not 0-4-8

Thanks Zed here is a updated timing chart.

I have a 123 distributor with a Bluetooth app I can set any timing I want. engine specs: l26 N42 head new stock bearing and rings. Schneider stage 3 460 lift 280 dur. timed 5 degrees adv to spec dual weber 32/36 dgv, I have a jet kit but need to get my o2 sensor working pacesetter headers 2.5in exhaust really good ignition components kameari twin idlers and adjustable cam gear 3 core rad with dual 12 in fans for cooling. heat shielding everywhere. a video of it running

distributor has done its job, and my z is alive again!!! I am so happy. Yes I know it could have been done cheaper, maybe an extra feature or two, but the install took 30 mins and I was the cleanest I've ever been when working on my car. Granted its recently cleaned and rebuilt. The distributor came with a black cap which I really wanted for oe type look. The tune isn't good, the carbs aren't set and I'm just happy the thing runs.

Woooo!!!! what the h happened? did it back fire so hard it blow your engine?

Thank you guys for the resources. I knew about the gm hei and actually bought one, but decided to return it. I will defiantly keep that trick in my sleeve to pull out in the future if needed.

The first paragraph will be a little bit of back story. I rebuilt my 260z mechanically this past 2-3 years, paycheck to paycheck, learning from my first project car. I have tried to do a sensible OEM+ type modifications. Last year I drove it 100 miles burned 2.5 qts of oil and decided to rebuild the engine. Fast forward i have redone the engine bay wiring harness while the engine was out. RELOCATED the ignition coil to the other side of the engine bay. i drove the car 50 miles after the rebuild then lifted it back on jack stands to do the suspension bushings and shocks. I also did a bit of wiring upgrades and buttoning up parts in various places. I have a no spark issue. I with the help of others close by have determined my problem to be a distributor problem. I took apart the dang thing and it looks like maybe a wire disordered or maybe even 2 had and these are needle thin wires inside a 280zx non turbo distributor with a black box on the side taking over the roll a points system would do, ECM, electronic control module. i bought a junkyard one that looked nicer than the others but had a non OEM ecm. this part did not solve my problem and test faulty by my method of use a digital multimeter. the 123 Distributor is slightly more expensive and a replacement I could find in descent quality. it will be interesting to see what results I get from this distributor. pic is the dizzy from the car originally, has reman marked on it, also its of 80s tech in a 74 car. the tiny wires I tried to solder them but just didn't work out for me.

I have decided to install a 123 on my 260z this thread has contributed to my decision, as I am highly curious of an upgrade potential: and adding complexity to the car doesn't deter me. My 280zx non-t dizzy upgrade was installed by PO many yrs ago with a reman unit, has failed. I would like to tune my engine with the app, and see the results. I will update when I can.

I already have the engine back down to the block in 21/2 hrs. its really easy after doing it the first time.

The bolt was snapped already and is the old bolt. I have a fresh one ready to replace it. I milled the head and all that. I just took everything apart. It could be the front cover gasket leaking? I'm not sure, the thing is it my first time with z's and having a project car like this.

I rolled the dice and I lost the bet:(

Okay sorry I need to clear the info up. 3 years ago bought 260z and spent 2 and half year in the garage fixing/correcting/maintenance of the car on a shoe string budget. I had a cruise for STL Z club it made the cruise 100 miles 2 qts oil used. this is a stark contrast to the ~40 miles its driven since I've owned it. Parked in garage and pulled everything off the block. Everything is back together after a couple months, with one thing i know for sure is bad. butttttttttt is it what is causing my oil/coolant mixing? Here's a little picture story, my z is in the back of the group photo the last day it drove.
