The FU engine came on the "GFU", "FU" and "MPG" cars (USA-market B210 and B310 fuel economy champion models). F means Five-speed. G means GX trim (not dual carb). U means USA (FEDERAL, except California). They got up to 50 mpg (21 km/liter).
1977 B-210 50 MPG (US gallon = 3.78 liter)
Contents |
B210
The FU model was a B210 Coupe fitted with A14 engine and 63a Five-speed transmission. The 5-speed was introduced to USA models from 1976-1/2, and to Canada models for 1977. 65 HP A14 with round ports.
5-speed models were only available in Coupe body style. All 5-speed models were fitted with FU engine. So for America, 5-speed was for fuel-economy, not performance option.
NOTE: When the FSM refers to the "FU models" apparently it is excluding Canada FUN vehicles.

A14 or A15 with 60-series five speed transmission. Available in all body styles: 2-dr, 4-dr, Coupe and Wagon.

- 0880- WHLB310FU Wagon, DX, A14
65HP - Economy A14 Engine. This engine got 47 MPG in the B310 with 5-speed transmission.
1976-1978
B210 engine was A14. Standard A14 was 80 HP, but FU engine was 65 HP. Round ports contributed to superior low-rpm operation.
- Round ports, low with swirl (non-shrouded)
- Closed chamber (previously open chamber)
- Passive air induction (non-FU has air pump)
- 1977 compression ratio: 8.5 (5.37 mm dish)
- 1978 USA compression ratio: 9.0 (4.08 mm dish)
NOTE: All 1978 Canada models used this engine, even non-FU Canada cars.
- 1977 FU engine used 1978-style electronic ignition
1979-1980
1979 FU engine was A14. In 1980 either A14 or A15 was fitted. Curiously, the A12A engine was not used in the fuel-economy models.
Cylinder head features:
- quench wedge chambers
- round 28mm (?) lowered ports
- Has round intake ports (like the A12 head). It has two small coolant holes below the intake ports, to provide heat for the intake manifold.
1981-1982
All 1981-1982 US models, including A12A, A14 and A15 used the same head design. So the FU models for 1981-1982 did not have a special engine. All engines these years were high-efficiency.
- quench head
- smaller dish in piston
- 35 mm intake valve (previously 37 mm)
- shrouded intake valves
- change from round ports to Small Oval
- Standard Datsun 1200 style cooling fan (not the larger typical A14 style)
Spark Plugs
For 1978 and 1979, FU engines were fitted with NGK "Multi-gap" spark plugs with the larger gap of 1.3 mm (0.051 inch). The FU engine locates the spark plug closer to the center of the cylinder, which is superior to the regular head.
- 22401-H7285
These plugs use a special distributor and static timing, but uses the same 12V coil as other Electronic Ignition models.
