Using the B310 electronic distributor in other A-series engines s a very simple swap, with only one minor modification needed to put it in an older 1971-1973 A-type engine. This distributor is factory stock on 1979-1982 Datsun 210 (North American version of the B310).

The 1980 Mitsubishi distributor on 1972 A12 engine. Note how it looks very similar to the 1971-1973 Hitachi or Mitsubishi distributor.

NOTE: This is not the same as the Hitachi electronic distributor as can be found in some New Zealand Sunnys and earlier North American B-210s. The one we are talking about here has a small 'black box' bolted on the side of the distributor.

Advantages

• stealth. Looks very much like a factory 1200 point setup
• Larger cap -- less chance to crossfire (important in humid climates)




• High-energy spark -- uses full 12V coil (no ballast resistor)
• No points to wear out, no dwell to adjust </ul>

  Mechanical

  1. If you are working with an old-style A-series engine (1966-1973), modify the distributor hold-down bracket to fit old-style block. The mounting bracket on newer distributors needs a slot cut with a hacksaw. For details, see Using Newer Distributor.

  2. Remove old distributor, Insert new distributor. And of course, set initial timing. For details, see the Ignition Timing article.

  
  

  Wiring

  Ah, this is the easy part, especially if you get a cut of the wiring harness when you purchase your distributor. But if you don't, it's still easy to hook up the wires.

  [ [1]

  Connect wiring as shown here. As you can see, the two wires on the distributor go to the two coil wires.

  <li>Remove the standard low-energy coil and ballast resistor, then bolt the 12V coil in its place</li> <li>I believe the condensor is optional, it is to reduce radio interference. I bolted the condensor to the distributor mounting screw. Keep it away from the vibration and heat of the engine (mount it to the body panel). One end of the condensor can go to the ground spade-connector on the distributor body</li> <li>One side of the ballast resistor has a 12V IGN feed, so connect the Black/white wire to this original wire (Black/white)</li>

  </TABLE> The Ignitor (elec. module) seem to be bulletproof. I'm told that the currently available replacement modules are junk, but the original Hitachi units are very good. They are still working after 20+ years!
