Daihatsu H series Engines (1.3 Hijet)

The 1.3 Hijet has the HC-E engine fitted which is a nice little rev happy unit, taken from the charade and later fitted to the Terios it is part of the H-series of engine which have been used across many different Daihatsu’s from the Sportrak (known in other countries as the Feroza or Rocky) to the Terios. In the Hijet it has been tilted over to approximately 70 degrees and fitted with a different oil pickup, sump, inlet manifold and cam cover to support the new lean over type installation. From research into different Daihatsu models it seems that all the different heads, blocks, cranks and manifolds etc are all interchangable allowing for serious customisation. There are examples of these H series hybrids making hundreds of horsepower though the use of turbo chargers and various standard and aftermarket components. You can obtain forged pistons, high lift and duration cam shafts, H beam rods and all sorts if you look hard enough. Coupling this H series engine to a Hijet gearbox could be a useful platform for kitcar builders or other vehicles including light weight race machines as the engine is all alloy and compact in design.
