Helpful guide in selecting the correct distributor
Created: January 31, 2006
This table can be used as a guide to selecting the appropriate curve for your particular application. Select either the standard engine specification, or if you have a distributor with a curve that works well already, you can read the Lucas service number from the side of the distributor body to match.
Installing Mini Main Studs
Created: April 10, 2000
On 2" inch main 1275 engines the use of main studs gives a solid improvement over the stock bolts. Factory bolts, at the very best, only have 65% of the clamping force of an ARP stud, and consider that the combination of the firing load and inertia at RPM cause loading's that amount to thousands of pounds. On the 1275 Mini there is something to look out for that doesn't arise on an inline engine. Due to the proximity of the gear box webs at both ends, there is not enough clearance for the nut.

Why is a camshaft like the heater in your house?
Created: February 25, 2014
Camshaft selection can be as complicated as you like, but for the ultimate performance, even if that means best gas mileage requires that you consider the entire envelope that the camshaft will work within. Non-technical issues such as intended application (street, race, milage or??), budget, expected RPM range, etc must be considered along with technical things like compression ratio, Cylinder head and valve sizes, exhaust system, carburetion, etc.

Camshaft Theory by Elgin
Created: January 28, 2006
Considerable information has been recorded about numerous aspects of the four stroke internal combustion engine. Nevertheless, only a small percentage of people really understand how it works and even fewer still know how to modify an engine to suit their needs. I will try to simplify this complex subject by discussing some basic principles that may be overlooked or misunderstood by the average person.
Kent Camshaft Fitting Rules
Created: January 27, 2006
The installation and first few moments of running are critical factors in the life of the camshaft and the following instructions have been devised in order to obtain maximum performance from the engine and to ensure a long and trouble free life from both the camshaft and associated components. These points are designed to be used in conjunction with the original manufacturers installation procedure.

This article has been written owing to the increasing amount of people who call Mini Spares stating that their 1275cc Injection type Mini will not start after fitting a new clutch, especially when they have purchased the parts from another supplier rather than a Mini specialist.
Clutch - Drive Strap Alignment
Created: May 29, 2003
If the pressure plate clutch plate friction face needs re-surfacing, get it machined to clean it up. Make sure the engineering company doing the job records the amount taken off, as the recorded amount needs removing from the tops of the 'horns' that stick up to ensure proper clamping force is achieved.
FULLY-FLOATING PRIMARY GEAR BUSH

Countless Mini enthusiasts have been dogged by primary gear bush hassles on 1275-based engines - in particular the one nearest the block (the front one.) Worn bushes are expensive and difficult to replace for the DIY-er because they must be machined to the correct size, a job that needs to be done very accurately.
Clutch Checking (Pre Verto)

Maybe your Mini clutch is working fine, or the action just doesn’t seem the same, or you're hearing noises you don’t remember hearing before. The following are some quick checks you can do to make sure the clutch keeps operating correctly or to reveal areas that may need some attention.
DIAPHRAGM SPRING - Pre-Verto types
Created: December 04, 2000
These are the shallow cone-shaped objects that the release bearing pushes on, with a steel band (disc spring) on the underside that presses against the flywheel. This provides the force on the clutch plate that ultimately passes the torque to the wheels, and is available with different spring rates/tensions dependent on the application.
Radiator Options for the Classic Mini

The cooling system in the Mini has used the same basic style radiator since it's begining in 1959 up until the introduction of the twin point injected cars when the radiator was moved to the front of the car.
Oil Coolers
Created: February 03, 2011
In the past, fitting an oil cooler was mandatory once an engine had been even slightly uprated. The main cause for this was the quality of Motor Oils available at that time. If the oil temperatures exceeded a specific point, then engine failure was almost guaranteed.

HOW TO CONVERT FROM GENERATOR TO ALTERNATOR
Created: September 16, 2005
Minis built up to 1969 (i.e. MKI  &  MKII) were positive ground while MKIII and onwards were built negative ground. The polarity of the alternator can not be changed, so if the alternator you have does not conform to your car, you must change your car. 
DISTRIBUTORS - working basics.
Created: September 15, 2000
To maximize power and economy potential from any engine, burning the compressed fuel/air mixture at precisely the right point throughout the engines entire rpm range is essential. This ‘point’ is generally somewhere before the piston reaches TDC on its power stroke described in degrees - i.e. 10 degrees BTDC.
DISTRIBUTOR - Electronic ignition
Created: September 15, 2000
Since the A-Series has such an efficient combustion chamber design, the standard points set-up is perfectly capable of providing sufficient sparks for effective combustion when new. And this is the problem. They require regular servicing to maintain maximum performance. This can be a chore, so is generally neglected.
Changing from Dynamo to Alternator
Created: September 01, 2000
Completing this change successfully, easily and neatly is pretty straight forward on a Mini. The alternator contains the regulator and cut out functions within it’s casing, so makes the regulator box used with a dynamo redundant. However, it is useful to retain the box itself and it’s connectors.
Distributor Adapter

This kit allows the pre "A-plus" distributor to be used with an "A-plus"block. Rotate the engine until the No. 1 cylinder is at Top Dead Center (TDC no.1) with both valves closed.

Quaife Limited Slip Differentials - Classic Mini Cooper
Created: January 26, 2006
The Quaife Differential powers both drive wheels under nearly all conditions, instead of just one. With an ordinary open differential, standard on most cars, a lot of precious power is wasted during wheelspin under acceleration. This happens because the open differential shifts power to the wheel with less grip (along the path of least resistance). The Quaife, however, does just the opposite. It senses which wheel has the better grip, and biases the power to that wheel. It does this smoothly and constantly, and without ever completely removing power from the other wheel.

IGNITION - Establishing a TDC reference point
Created: September 26, 2000
Establishing an accurate TDC reference point is of paramount importance when developing and monitoring ignition timing (and cam timing come to that). When an experienced engine builder assembles an engine - no matter whether for road or race - he will establish an accurate TDC indicator that can be used for ignition purposes.
DISTRIBUTOR- Initial ignition timing set-up

Any deviation away from the original standard engine specification, or where a dizzy from another source is used in the engine you have, the ignition timing will generally be different from that set by the manufacturer.

Any dizzy can be set to get maximum power. No problem. Unfortunately that's only one spot on the whole power curve/rpm range. If the curve isn't right elsewhere, the engine will be either loosing power - in some instances by substantial amounts - or detonating its self into oblivion and a costly re-build.

The overriding factor that influences just what is best for an A-Series engine is the block's propensity for flex at higher rpm, and the crank's equal propensity for flex at the same sort of rpm levels.

When Omega quit making A-Series pistons, Mini Spares took it upon themselves to design and build a better Piston. Recruiting the AE Hepolite Group for their unquestionable and renowned design and manufacturing expertise, the goal was to produce the most robust piston possible given reasonable cost and weight limits. Applying current technological advances incorporating their very latest hi-spec AE109TF lightweight alloy and special double heat treatments, the result is an extremely durable piston that will withstand greater cylinder pressures at higher RPM than any other currently available.

Over the years, there have probably been a dozen "stock" 1275 pistons. Currently, three different designs are available from AE/Hepolite as "stock" replacements.
