North America

In North America, the B210 was marketed as the "B-210" (with a hyphen) or B210 (without). NOTE: It was not the 210, that is a newer Datsun.

1974

For the 1974 Model Year the goals were:

  • conforming to anti-pollution regulations
    • EGR added
    • Air Compensator now standard
  • requirements of FMVSS
    • notably large heavy bumpers
    • starter interlock

One of the most obvious changes from the B110 -- other than the all-new sheet metal -- is the large 5-mph "park bench" safety bumpers of the type fitted to all 1974 USA autos.

Since both affected performance, only the high-grade A13 engine was offered (model HLB210) to keep performance on par with the lighter Datsun 1200.

A13 Engine for USA market: see wikipedia:Nissan A engine.

  • New 1974 A Engine Redesign common to all A-engines
  • Tall-block engine (like A14) 30 mm higher than previous A12
  • 77 mm stroke, up from 70 in A12 engine. Bore same as before

Also causing some consternation was an incredibly complicated starter interlock. A seven-input (!) transistor "brain box" prevented the engine from being started if the driver's seat was occupied but the belt unfastened.

Seat belts for 1974 were 3-point, but unlike B110 the shoulder belt is semi-permanently fastened to the seat buckle (no need for a zip tie). Also the inboard belts have a round flexible-wire design so they don't fall down around the seats when not in use. This is a good swap for the B110 belts.

1975

For 1975, the main design points were:

  • Introduction of the California-destined model (Chassis Code suffix 'N')
  • Introduction of factory Air conditioning. Previously, only dealer-installed Aircon was available
  • As usual, emission and safety requirement changes

Because of the performance-robbing emission and weight-gain changes in the USA market, the larger A14 Engine was adopted to keep performance on par with last year's model. This triggered a cascade of parts changes, including:

  • Intro of A14 Engine
    • stronger 4-speed 60-Series Transmission instead of the 56-series fitted to A12 engines. It has a higher first gear
    • Heavier clutch to handle increased engine torque output (now 794 lbs, up from 694 lbs for A13 engine)
    • stronger H150 differential
    • 140 mm (5.55") wider Radiator core
      • Fan Shroud now standard equipment
    • Longer front coil springs
    • stiffer rubber Engine Mounts
    • Automatic Transmission changed from air-cooling to water cooling

Emission Controls

  • Intro of Air Pump to Sunny family
    • Cylinder head recast with air passage to each exhaust port
    • Port for anti-backfire valve added to Intake manifold
  • Evaporative changes from crankcase-storage to charcoal canister
  • Intro of spark delay valve
  • Leaner carb settings:
  • Remove engine compartment heat from engine
    • Intro of fresh-air ducted air cleaner
    • Two-stage Idle Compensator
    • Heat Shielding:
      • plate around carb
      • insulator between throttle body and center body
      • shield between intake and exhaust manifolds
      • stainless bolts in carb (to lessen heat transfer)
      • stainless bolts for manifold mounting

California Model: In 1975, California had a population of 20+ million. This size made it a very important market to international companies, so when California legislated the strictest emission limits in the world, the automakers said "Yes, Sir!"

  • Intro of catalytic converter, which made the following needed:
    • Modified fuel filler and hose
    • Modified floor pan
      • Modified driver's seat (thinner, and cutaway on inside). Driver's inner seat belt also redesigned slightly
    • Converter Floor temperature warning lamp
    • Floor insulation (full jute padding)
    • Routing of fuel, brake and EVAPO tubes rerouted under car: Along outside stiffener instead of in tunnel
    • Exhaust piping insulators
    • Intro of fully-transistorized ignition, adapted from 240Z. See B-210 Electronic Distributor Swap
    • Altitude compensator (for high-altitude markets within California)


Safety:

  • bumper overriders add (rubber bumperettes, a la B110) to meet the Cost Saving Act. 1974 models had 'smooth' bumpers
  • Illuminated light switch introduction
  • Brake Hose Marking (FMVSS No. 106)
  • Bumper height requirements (FMVSS No. 215), raised ~ 2 inches

Misc:

  • 50A Alternator (LT150-19) now fitted instead of 35A
  • Adoption of 610 Voltage Regulator (TL1Z-82)
  • Engine crossmember clearnanced slightly for aircon compressor


Cool Changes for 1975:

  • Wood-grain shift knob (Canada only)
  • Three-spoke steering wheel (Canada only)
  • Speedometer with trip meter now standard!
  • Door Mirror mounted 100 mm forward relative to 1974 model
  • Intro of ingition relay switch (California only), no more burned switches?

1975 Standard Model

In the height of the Fuel Crisis and economic problems, Nissan introduced for the first time to the american market a Standard (base) model Sunny. It was a low-cost 2-dr sedan.

Standard models have an 'S' suffix in the model number

This also marked the introduction of the B-210 Deluxe name (fitted to all existing sedans), to differentiate it from the new standard model sedan.

This is the difference, among other deletions, this equipment is not fitted:

  • Trunk mat
