Randall Posted February 3, 2013 Share Posted February 3, 2013 (edited) So I am almost done with my second l28 build so I am very familiar with these motors. Except this one is being setup for a turbo instead of the triple webers i had on it. I was planning on locking out the stock VR distributor and using it to control timing using MS2. So i have a 280zx distributor from my triple weber setup and i also pulled a distributor from a 76 because i like the long tail coming off of the VR which will make wiring very easy. So onto the problem, the motor is all buttoned up still on TDC from setting the chain. I go to put my 76 junkyard distributor on and it is 180 degrees off!!!!! I was almost at a loss for words cause this is my second time at this. (on my first motor build the same thing happened except I had turned the motor after i set the chain so what a thought was TDC was not when i installed the pump) This time i know i did everything correctly so just out of curiosity i grab my 280zx distributor and it points dead on at #1 on the cap!!!!! How could a distributor be 180 off and another be correct? Edited February 3, 2013 by Randall Quote Link to comment Share on other sites More sharing options...
djz Posted February 3, 2013 Share Posted February 3, 2013 Distributor incorrectly assembled? I'm think from memory you can remove the offset tang part and turn it around if you remove the roll pin in the bottom. Quote Link to comment Share on other sites More sharing options...
Randall Posted February 3, 2013 Author Share Posted February 3, 2013 That's what I was going to check but was not sure. Quote Link to comment Share on other sites More sharing options...
Randall Posted February 4, 2013 Author Share Posted February 4, 2013 Well I had to pull it apart anyway to lock the mech advance. The mech advance weights are attached to the offset at the bottom. The top section with the rotor and slots can fit on correctly or out 180 degrees. So I just rotated it 180 and filled the slots with JB Weld and then reassembled.

skirkland1980 Posted February 4, 2013 Share Posted February 4, 2013 I had this same problem. I'm not sure where you used jb weld. I used mig weld. Quote Link to comment Share on other sites More sharing options...

Six_Shooter Posted February 11, 2013 Share Posted February 11, 2013 LOL, "The dizzy was 180* off." I enjoy reading that every time. The dizzy doesn't care which way the rotor is pointing, when cylinder #1 is at TDC, just use that tower for your #1 cylinder and install the rest of the wires accordingly, going around the dizzy cap in the correct direction. The only reason there is a common point for the #1 to be set is for reference to an FSM. Quote Link to comment Share on other sites More sharing options...
skirkland1980 Posted February 11, 2013 Share Posted February 11, 2013 If mine was 180 off my #6 spark plug wire wouldn't reach. Quote Link to comment Share on other sites More sharing options...
beermanpete Posted February 11, 2013 Share Posted February 11, 2013 Mine is "180 out" as well. It works fine after rearranging the plug wires but they overlap each other more and don't look as nice. Quote Link to comment Share on other sites More sharing options...

Last rebuild i screwed up and it was 180* out from me installing the oil pump wrong so i just moved the wires around like you stated.
