SwanSong Engineering (SSE), based in Swansea, Wales, and is an engineering firm that specialises in engine designing, but also is available for car setup and technology.
Most famous for producing the 2L all aluminium V6 that powered the original Keika, SwanSong are capable of designing advanced engines for all purposes.
SSE uses a simple code system so you can tell what most engines are just from reading the name. For example:
D2RC - 20 NA 2BTWC
D2 is the valve type.
R is the engine configuration.
C is the decade it was produced in.
Meaning of each letter here: https://docs.google.com/spreadsheets/d/11uegWh9KJZpq0c_p0P5USrPSHY_zCNndOBfO2e_1_sU/edit?usp=sharing
20 is the first two digits of the engine capacity in L.
NA means Naturally Aspirated. Single Turbo engines are T. Twin Turbo engines are TT.
2B means 2 Barrel Carburettor.
TW is Twin Carburettor.
How to access SSE services:
DM engine limitations. Make sure you include all limits, including PU and ET, and a general goal for the engine.
SSE does not manufacture most of their engines themselves unless they are very low production.
Engine tuning for existing models is also available, if you have a current model that needs a performance variant.
Car tuning or setup will also be available if requested too.
Below will be engines for sale, or changes we have made to existing cars.
D2RC - 20 NA 2BTW
Designed for the 1966 Keika, the goal for this engine was to be lightweight and efficient, and cheap to run, and no costs were to be added anywhere it wasn’t needed, but otherwise no strict limits were in place
As a result, the engine was an all aluminium V6, at just under 2L. Featuring DOHC to be efficient, and an undersquare [74x77] setup to be lightweight. The internals are all cast iron, since the mild cams for a wide range of power meant the engine didn’t require the revving potential of forged pistons or conrods.
Twin 2 barrel carbs, with a standard intake, which was chosen to keep services costs far lower. The extra power wasn’t seen as worth it, especially as the engine was loud enough as it was. It was setup with an advanced ignition timing and sporty, but fuel economy minded engine setup. The redline is right at the limits of the internals.
Lightweight long tubular headers brought total engine weight down to under 115KG.
This engine did without mufflers because of the extra weight they added, and since it went in a track car, comfort wasn’t important.

This is the right kind of engine for the original Katana - small, light, responsive and punchy.
