  1. I bumped in on this thread through search because I'am looking to find a solution to my jumping tach. I have a couple of instalation diagrams for your petroniks and msd box that I will post. In the mean time post 11 mentions resistor of 4.0 or 5.5 ohm to be installed. I installed a 2.2ohm resistor at the passenger side under the dash and its still not working. (260Z/74)

    My question is; My ignition is stock and if I install a 4.0 or 5.5ohms resistor on my factory wire harness would it cause any harm?

    Here are the pic for you guys with petroniks and msd box;

  2. No I did not make this, but it should not be too difficult to make. Just follow the same principle. To me it looks like a front strut bar modified to fit the t/c cup. The owner of this car also did the same to the rear following the same principle.

  3. I have the same problem with a jumping tach. I change the resistor in the passanger foot well like suggested above and still have the same problem. Iam thinking maybe the coil since it seems its the original one but the car runs fine so I do not know what else to do. My car is an early 260Z 5/74.

  4. It would depends on how long you have this knock problem. In any case its wise to check everything. Measure your cylinder for roundness, your connecting rod for warpage and your crank journal for out of round. Get yourself some precision measuring tools. If you have the "how to built an l6" from frank hosowitz (sp?) it shows you how to check for all this.

    Good luck!
