Took this at Roskilde a few years back, only because of it being so unusual,It looks as if it's made to take a non 'A' series engine.

B Series engine was fitted transversely in the fwd Austin/Morris/Wolesely 1800 'Landcrabs' also with the gearbox in the sump just like the Mini. (The photo above is not however a B series transverse gearbox)

Peter Baldwin and his 'Baby B6' Mini used a Gordon Allen built BDA engine

I remember there was also a 2-cylinder 850 BDA!
Mini 850cc BDA Engine
One engine of this type came about by accident, literally! A 1300 BDA engine, fitted to a Mini, blew up and destroyed two cylinders. The two good cylinders were cut from the engine and used to produce a two cylinder engine by means of special blanking plates and crankshaft. At first the engine did not put out much power but when its problems were sorted it put out 115bhp, over 35bhp more than any engine of its size.
Gordon Allen's Mini 850cc BDA Engine
Unlike the other 850cc BDA mention above, this unit was a purposely designed two cylinder engine built for racing Minis. A specially manufacture alloy block and forged steel crank formed the basis of this engine. Bores were 85mm diameter and the stroke 74mm, giving it 848cc. A halved, standard Formula Atlantic BDA head with full size valves giving an 11.8:1 compression ratio was employed, and this was fed by a single 45DCOE Weber. The engine was mounted on a Mini transmission using an adaptor plate. Early versions of the engine gave an extra 20bhp over a standard racing 850cc A Series, this difference nearly double in the next 5 years.

Don't see many of them around now even at the classic car shows...........they look just like a giant Mini under the bonnet really, but clutch is an engine out job usually, so sent many to the scrapyard early.

Photos of a 1800cc B-Series engine transverse in an Austin 1800 Landcrab 'Big Mini' I saved from the scrapman a couple of years back, gearbox is in the sump as for the Mini A series:
