Engine transplants - Ancillary parts

Engine mountings are a whizz to fit as the Mini ones fit straight onto any of the other units. Just remove the Metro/AA/1300GT ones and swop the mounts over from the Mini unit. If they’re split, fit new ones, they’re cheap.

Terminology -
BBU - Big Bore Unit
SBU - Small Bore Unit

NOTE: This information covers transplanting large-bore engine units into small-bore engined Minis. For further information for exact differences between pre-A+ and A+ units, see relevant separate article.

If they’re split, fit new ones, they’re cheap. If using the AA/1300GT unit - it's advisable to cut off the 'wings' on the front plate that carried the engine mounts on the radiator end.

Engine transplants - Clutch and flywheel assemblies

To go in to all the possible permutations would take a few chapters on it’s own. Suffice to say that the Metro had a few weirdo fitments such as cable operation, an in-line ‘damper’ (some got fitted to Minis too - eek),

C-AEG423 - LIGHTWEIGHT STEEL OUTER FLYWHEEL SECTION, VERTO TYPE

Reduction of rotating mass releases more power to accelerate the car as the engine sees less weight to accelerate. Considering for a Mini that a mere 1lb reduction in the rotating mass of the flywheel causes a loss of accelerative weight to the tune of around 12lb - the benefits of rotating mass reduction are obvious. The C-AEG423 weighs some 4lbs less than the standard item.

To extend it's range of superior quality, light-weight steel flywheels, Mini Spares has produced this component to give the later model, SPi Mini owner the benefits from such weight saving. This component has the flywheel sensor reluctor ring machined into the flywheel itself. However, it is NOT compatible with the standard injection diaphragm/spring.

Verto to Pre Verto,Clutch swap

TEST If converting from A plus verto type clutch to the original Diaphragm type these are the major components you will require:

All the major extra parts required to convert from Verto Clutch to Diaphragm type parts (in brackets indicate alternatives)

6 x GHF323 shakeproof washer 3/8” UNF
2 x GFK5240 bolt remote housing short 1” UNC
1 x 88G508 flywheel keyway – pre verto (EN24T)
6 x 2A3658 clutch flywheel strap
1 x 2A3601 clutch return spring anchor
1 x CLZ628 clutch arm pin – bottom
1 x CLZ518 clevis pin for clutch arm at the top
1 x 22A747 flywheel bolt pre verto
3 x 2A3657 clutch bolt long cover to pressure
3 x (C-2A3657 ) clutch bolt long cover to pressure

When most folk talk about limited slip differentials for the Mini, minds immediately turn to the name "Salisbury". Indeed many think that word covers any LSD for the Mini. This, of course, is not so. The Salisbury diff was designed in the 50's at a time when race cars were not sophisticated, tyres were usually cross-ply with limiting grip due to poor compounds, and tracks were more than "a little bumpy".

Identical Twins Mini Spares need no introduction. For Mini nuts it's a Mecca for spares and tuning and even the non-converted can't have missed the company's involvement in the Minis comeback in the Monte Carlo Rally.
