Engine transplants - initial information and engine choices

Is this familiar? - You take the small one out; you put the big one in. In, out, in, out, shake your fist about, you do the hokey-cokey and you turn around, that’s what it’s all about...

Terminology -
BBU - Big Bore Unit
SBU - Small Bore Unit
Bodge - English term for 'make do' engineering- assured to fail at an in opportune
Moment.
Dizzy - Distributor

NOTE; this information is largely for transplanting large-bore units into small-bore engined cars.

Is this familiar? - You take the small one out; you put the big one in. In, out, in, out, shake your fist about, you do the hokey-cokey and you turn around, that’s what it’s all about...kinda sums up the situation many folk find themselves in when attempting to endow their beloved Min with a more impressive turn of speed.

6 OF THE BEST We have now developed a 6-speed gearbox and sequential gearchange for the 5/6 speed gearbox. (Sequential is like a motor bike change, all in line and not "H" shape like the MinL) They will only be made in small batches when required as demand will be very slow. The original "A" plus design of gears were first drawn up in the 1940's and not put into production until 1980. Although quiet compared to the previous gears of the four synchro gearbox they are much weaker by virtue of the thinner gear pitch. On the Mini Spares project car we have the old type gears with'S' ratios converted into a 5-speed and it has proved indestructible by everybody who has thoroughly tested the car with its 8-port engine power. As the ratios were not very desirable for tuned motors, we are contemplating producing a whole new helical cut set of nearly indestructible gears which will be quiet for road use.
