Some 1980-1982 Datsuns in Asia markets came with an OEM (factory) EFI system. Nissan called it "EGI" -- Electronic Gasoline Injection (日産 EGI). This is the "rare as" A14E Injection motor. At 92 horsepower it was far superior to the carbureted 80 hp A14/A15.
quote:
a friend of mine has a system that came on the A14 in the M10 Pulsars (very first ones). The set up he got came from Singapore
The A14E engine came in:
- 1979-1981 Langley (N10 Pulsar) -- Asian markets
- 1978-up Feb - Sunny 1400SGX-E Coupe -- Asian markets
A14E was available until October 1980. It was replaced by A15E in November 1980.
"A" series engines are produced in Aichi Machine held in Aichi plant.
Quite a large horsepower difference:
- A14E: 92 PS @ 6400 rpm, 11.7 kg-m @ 3600 rpm
- A14: 80 PS @ 6000 rpm, 10.2 kg-m @ 3600 rpm
A14 EFI manifold
SSS as I remember at one stage they had import carbie A15 engines for round $600 and injected A14 and A15 for around $800
Reportedly, Nepean Sports classics in Castlereagh NSW was selling import motors. carlos' son ran one. These are fairly sought after by the rally guys as the narrow runners provide torque and the length also good top end, too small for a big A15 though.
These possibly came in later model Nissan Vanettes, the reason they seem rare is both my manifolds broke across the bottom of no's 1 & 2 inlet runner. Plus it suffers from reversion with a big cam.
These were also available in asian markets (Japan, Singapore, etc).
quote:
- A14 EGI = HB310 (1978-1980) Type-GX & SGX
- A15 EGI = PB310 (1980-1981) Type-GX & SGX
As for the name in Japan, Nissan calls EGI and Toyota EFI.
Although the EGI system should excel Carburettors in the performance, old EGI is inferior to Carburettors.
Discussions:
As you can see here, the setup is nearly identical to 1980 200SX EFI system:
- This car is missing the air induction piping that goes across the radiator (see 200SX EFI for layout and diagrams)
B310 Factory Setup
Performance
This factory Nissan setup was designed for typical mass-market street performance. It is not a racing system. Expect better low-speed horsepower performance than a stock DCH306 carburetor (due to the longer runners), AND increased peak horsepower.
However, in a heavily modified engine, carburetion has more potential:
Quote
A factory EFI setup imported from Japan was tried, and found to be much smoother, but ... restrictive above 6000rpm when used with the [racing] cam.
