Very interesting video! The engine situation is certainly an interesting one. It made me go and look up some Sabre specs:
Quote:
SABRE I, 2,000 hp, (1939), Type E107, 24-cylinder, horizontally opposed, H-shaped, 70-30 per cent water/ethylene-glycol cooled, sleeve-valve. Bore/stroke 5.0 x 4.75 in. Vol. 2,240 cu in. (127 × 120 mm. Vol. 36.65 litre). Compression ratio 7:1. Two-speed, medium/fully supercharged, 4.68: and 5.83:1. Geared, spur .274:1. L.H. tractor-drive. Plessey Coffman cartridge starter. (Typhoon F.18/37, I)
SABRE II, 2,300 hp, (1940), (experimental .322 reduction gear). E115. Plessey Coffman cartridge starter. Length 82.25 in; width 40 in; height 46.0 in. (Typhoon II, Tempest I)
SABRE IIA, 2,235 hp, Sabre I modified for mixed matrix radiators. Similar to Mk VB . Altered ignition and plugs. Supercharger ratios 4.48:1 and 6.26:1. Reduction gear ratio .274:1. (Typhoon I, IB, Tempest V)
SABRE IIB, 2,400 hp, similar to Mk IIA, S.U carburettor. (Typhoon I, IB, Tempest V)
SABRE IIC, 2,065 hp, similar to Mk VII but with supercharger ratios 4.73:1 and 6.26:1. S.U. AQV carburettor. (Typhoon I, IB, Tempest V)
SABRE III, 2,250 hp, similar to IIA, to suit Firebrand. Higher rpm.
SABRE IV, 2,240 hp, (1943), as Mk VA with R.A.E.-Hobson fuel injector. (Typhoon I, II, Tempest I, V)
SABRE V, 2,600 hp, (1944), E121. Development of Mk I. Increased boost, redesigned supercharger and induction system, supercharger ratios 4.68:1, 5.83:1. R.A.E. BI/NS2 fuel injection. (Tempest I, V, VI)
SABRE VA, 2,600 hp, as Mk V with Hobson-R.A.E. NS4 fuel injector. Inter-connected, single-lever propeller and throttle controls. Length 82.25 in; width 40.0 in; height 46.0 in. (Tempest VI).
SABRE VI, 2,310hp, similar to Mk VA, with Rotol geared cooling fan and annular radiator.
SABRE VII, 3,500 hp, E118, 122, generally similar to Mk VA, except for being strengthened to withstand higher powers available with water/methanol injection for take-off and combat power. Length 83.0 in; width 40.0 in; height 47.75 in.

Looking at this list and the specs, it sounds like the green Sabre that was discussed in the video may be a Sabre V, with the other one being an earlier Sabre II or something along those lines. The Tempest V used Sabre IIA, IIB or IIC engines according to Wiki... but putting a later model engine in it would make sense if at all possible. It would make it a Tempest VI equivalent I guess.
