1600/2000 Datsun Roadsters 12V Electronic Ignition Distributor Installation
First of all, if you decide to not use the detailed instructions below, at a minimum, don’t overlook the following items: 1. You must install a 12 volt coil (see details about acceptable coil winding resistances below) 2. Bypass or remove the ballast resistor (if you remove it, connect the 2 wires and insulate) 3. Open the spark plug gaps to 0.039” to 0.043” 4. Set the ignition timing (it’ll be the last time you have to do this, unless you remove the distributor in the future). Timing specs are below. The nomenclature used in this manual is consistent with Nissan’s. There is a diagram with part descriptions at the end of this document that you may need to refer to, in order to understand part descriptions. With this upgrade, there will never be a need to adjust or replace points again. High engine rpm performance will improve because points bounce will be non-existent. After setting the timing, it remains unchanged. It’s a completely self-contained distributor with a simple 2 wire hook-up to the coil. This distributor is built to produce 15° of centrifugal advance at the crankshaft, which is identical to the non-smog roadster distributors (pre-1968). Compared to the distributors for emissions equipped roadsters, the non-smog advance makes a roadster engine run much better and helps prevent overheating problems. Also included at the end is a troubleshooting section for the electrical components of the EI distributor.
