B-210 Electronic Distributor Swap

From Datsun 1200 Club

Categories: Engine Electrical System | Ignition Modifications

In USA, starting with 1975 California B210 models, a fully-transistorized Electronic Ignition was fitted, adapted from the 240Z. It is commonly called the "Remote Ignitor" distributor, and was expanded to all USA models in 1978. It is of the Hitachi D4F type. This was used by other 1975-1978 Datsuns in USA and Canada (including L20B engine).

Contents

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

Overview

The B210 EI uses the same distributor housing as with other A14 engines (same as points-type).

The 1978 distributor. Looks very similar to the stock B110 distributor.

This distributor is factory stock on all 1978 Datsun B-210 (USA versions).

Using the B-210 Electronic Distributor Swap in other A-series engines is a fairly simple swap:

  1. If using in an A10 or older A12, perform the usual minor modification needed to put a 1974-up distributor in a pre-1974 engine. See Using Newer Distributor
  2. Set the engine to TDC, remove old distributor and insert new distributor, in correct timing
  3. Bolt the control unit somewhere. For reliabilty it should be inside the cabin for protection from dampness and vibration
    This step makes the B-210 swap a bit more difficult than the B310 Electronic Distributor Swap
  4. Wire the control unit to the coil and IGN+ (3 wires)

Identification

When you remove the cap, you can see the unique angle-pickup and reluctor of the Hitachi D4F system.

Further identification is by looking at the control module, located under the dash on the kick panel.


NOTE:
  • 1978 USA models used a high energy ignition module with full 12V coil
    Also used by all GFU models (5-speed, which was introduced Dec 1976)

    COIL: 22433-H7280
  • 1976-1977 CAL Interchangeable with 1975 CAL unit. These earlier control units have screw-type terminals, as opposed to push-on connector for the 1978 controller.

    COIL: 22488-H73012
  • 1975 California models used a dual-resistor ballast. Both primary and secondary coil terminals were wired into it.

The distributor with Ballast Resistor looks the same. While the resistor setup is better than stock (it eliminates the points) ... if you have a choice you definitely want the high energy setup. I'm guessing you could use the 1975-1977 distributor and control unit along with a 12V coil and no resistor, but don't know for sure whether the controller will handle the higher coil load.


Parts Needed

When buying/looking for a setup like this, get:

  • distributor + rotor & cap (or buy new cap & rotor, it's the same as all later models)
  • control unit. A new control unit is about $175-$200 USD, so be sure to get the used one
    22320.jpgAlbum click to view
    NOTE: If the Control Unit is missing, you can use an inexpensive GM HEI module
  • (optional) as much of the wiring harness as you want. At least the control wiring plug makes it easy. The rest is just wires
  • Matching coil. You can probably use any coil with the right ohms (0.7 ohms for the high-energy Hitachi E12-27, or standard 1.5 ohm coil w/ballast resistor for the lesser Hitachi boxes)

Source

Hitachi D4F distributor for A-series engine can be found in these models:

USA B210
CAL from 0974      1975-1978 model year
FED GFU from 1276  1977 model year 
FED ALL from 0877  1978 model year
CANADA: points type only

For distributor part numbers, see Hitachi_D4A_Distributor#D4F_EI_TYPE.

Testing

See Testing in the factory service manual.

The two pickup wires should read a about 750 ohms resistance. And using an analog voltmeter, should waver while cranking.

Mechanical

1. Modify distributor hold-down bracket to fit 1971-1973 A-type engines. The mounting bracket on newer distributors needs a slot cut with a hacksaw. See the Using Newer Distributor article.

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

Mounting the control Unit

4190.jpgAlbum click to view

On a factory install, the 'black box' for the B210 distributor mounts inside the car on the right kick panel. So it may be important to keep the box away from moisture, excessive vibration or high underhood temperatures. The box is called the "Hitachi Transistor Ignition Unit" (aka TIU/T.I.U./electronic ignition module/control module).

The odd-looking junction box is not really necessary to use, but is handy to connect the "inside" wiring with the "outside" wiring.

Wiring

Ah, wiring is the beautiful part of this swap, 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.

4191.jpgAlbum click to view
wiring - connect it as shown here if you don't have the wiring harness

  • Remove the standard low-energy (points) coil, then bolt the B-210 12V coil in its place and reconnect the wires
  • If using the high-energy box (1978) and coil, bolt a wire across the ballast resistor terminals so it always delivers full voltage to the coil

  • NOTE: California models routed the power through an relay (ignition relay). I'm not sure how it is wired, but you can simply just not use the relay and wire it as shown here.

Adjustment

No periodic adjustment is required. Before or after installation, set the Air Gap to .008 to .016 inch (smaller than a points gap).

Air Gap: 8-16 thousands inch (.2 to .4 mm)

At tune-up intervals, check the condition:

  • Air Gap
  • Vacuum Advance module (does it leak)?
  • Bearing plate? Move smoothly?
  • Inspect Cap & Rotor, wash if dirty. Replace if burn marks found in cap.

Part Numbers

Distributor:

  • D4FB-03 7904 22100-H3760 (and others)

Cap & Rotor

The Hitachi D4A cap & rotor also fits Hitachi D4F electronic ignition and Hitachi D4K electronic ignition. A-series, L-series and Z-series four-plug distributors use the same cap. Also fits Subaru, Honda and Isuzu with one of the above Hitachi types.

Cap

Part Number and aftermarket caps interchange, but differ by color, type of terminals (brass vs aluminum), cap finish material, presence or abscence of anti-tracking bosses inside, resistor type, vent/no vent, etc.
