IIRC the bakkie still uses that A-series engine originally designed by Austin, which clearly has some limitations of an older project. Would you ever consider an engine swap?

BTW what about the Diesel scene there in SA? I see lots of people there adapt Ford Essex V6 and a variety of V8 engines into nearly everything back there, but I don't find too many references of Diesel swaps (except for a Landcruiser 79 with a Cummins ISF2.8 replacing the 1HZ).

I did consider an engine swop, possibly the Nissan SR20 engine as its easily available and has been done many times before.

The Ford Essex engine swops are from back in the 80s-90s. These days the majority is 1jz, 2jz and Lexus V8 swops into anything and everything LOL but more for performance than economy.

Older diesels are not popular here for some reason. Id love to find a diesel power plant that would fit but ive been advised against it on the Nissan 1400 as there are not many options available. Newer model cars with tdi engines are pretty popular but to get one of them to fit would require more work than its work unfortunately.

There are many engines between 1.7L to 2.5L that wouldn't be too hard to fit into the 1400. Even the 1.3L Fiat Multijet could get the job done if you would consider something with electronic injection, and IIRC it has already been used in at least one RWD application in India before the phaseout of new Chevrolet car sales there.

One option to improve the efficiency of the gas engine would be to increase the compression ratio to say 10.5:1 by planing the head, and porting intake and exhaust passages. Depending on the fuel available alcohol injection or some other means to reduce pre-ignition might be needed. A local machine shop could do this without pulling the engine.

If the OP settles on more extensive engine mods instead of the aerodynamic and riding style adjusts it would be quite tempting to try a Prius-ish emulation of the Atkinson cycle in order to avoid the need for either premium fuel or any supplemental injection. Even though I am favorable to warer/alcohol injection for special/high-performance applications, it may not be the most practical approach.

BTW it may be easy to do the tuning without removing the engine block in the motorcycle, but in the bakkie if the OP eventually decides to get a fuel efficiency-oriented cam regrind it wouldn't be so easy to do so without taking the engine out since it features an OHV engine.
