Timing Chain Replacement for A-Series engines
Created: February 28, 2018
Building an engine is very much like most things in life- the more attention to detail you give an effort the more likely you will get the results you were looking for. Whether you are installing a new stock or performance camshaft or even simply rebuilding your motor with the stock camshaft getting the valve timing correct is one of the more important things that you can do.

Choosing The Right Timing Set For Your Engine with an quick review of timing chain tensioners. Camshaft selection can be as complicated as you like, but for the ultimate performance, even if that means best gas mileage, the decision requires that you consider the entire envelope that the camshaft will work within.

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 & Timing 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.
Camshafts - Scatter cams, pros and cons
Created: August 31, 2001
This whole 'scattering' deal has befuddled many. The simple fact is the principle is very basic and easy; it's getting a cam with the right profile and figures applied to it that's the hard part.
Cylinder Head
Classic Mini Cooper rockers, push rods and more
Created: December 21, 2015
When you are trying to build a motor to get the ultimate of performance you often optimize the life expectancy of the entire assembly. One such area centers around the rocker assembly. In general the rockers are part of the process that translates the lobe of the rotating camshaft to the vertical deflection needed to open the valves on the cylinder head.
BMC A-Series Valve train - Setting valve clearances (lash)
Created: September 30, 2004
A question that has cropped up frequently on the message board lately, and one that I do not ever recall having been set down in print in any magazines, is that of how to decide what the valve clearances should be when changing from the standard rocker gear to higher-lift options. So I thought I wo...
Rocker gear - General compendium
Created: August 28, 2002
Whether you’re building a solid road performer or fire-breathing monster, the main goal is to improve air/fuel flow into the engine. The more you can get in, the more power you can get out. Cheapest chunk of power improvement comes from sorting the asthmatic manifolding and exhaust by applying a stage one kit. Then what?
Rocker Gear
Created: January 30, 2000
The new generation of short period, high lift cams have been developed to give the best results in large bore engines when used in conjunction with 1.5 ratio, hi-lift rockers. For the small bore range, the stock 1.3 ratio is optimum. In certain instances ratios of 1.7 to 1 are of benefit - but is really only applicable to fully developed race engines.

Longer Connecting Rods in a Mini Cooper
Created: August 05, 2010
Longer rods provide for a longer dwell at piston TDC, keeping the combustion chamber small for a longer period as the expanding gases push against the piston. This extracts more power from a given air/fuel mixture thus increasing combustion efficiency.

Classic Mini Engine - Metro engine identification data
Created: August 12, 2004
This simply guide will help you identify your Mini or Metro engine when original serial numbers are still in place. A word of warning - whilst the data given here is as accurate and complete as I could make it without 6 months-worth of hermit-like investigation, there are bound to be oddities. Austin/Morris, BL/Austin Rover Group/Rover were never dedicated at keeping 100% correct records, particularly post 1970 - that's why Heritage really struggle with trying to identify cars manufactured after 1969. The Metro data - or lack of it - proves the point. It's nothing like as comprehensive as the Mini stuff.

LUBRICATION - Oil, what it does and how
Created: February 03, 2011
It’s criminal. Folk spend fortunes putting together super-sonic motors, only to skimp on the oil they use. Why? Oil’s oil right? Wrong. Even if it’s a standard engine, it deserves TLC considering it's extremely hostile working environment.
LUBRICATION - Temperature critical
Created: February 03, 2011
The correct running temperature of the oil is perhaps even more important than the water/coolant temperatures - so let us consider how to control them. Mainly because it seems to be the most misunderstood of the whole process, and oil cooler fitment almost a reflex when over-heating occurs where a tuned engine of any type is concerned. And in many cases on standard production road cars for that matter.

About a year ago I read about the reduction of zinc dialkyl dithiophosphate (ZDDP) in the oils supplied with API approval that could affect sliding and high pressure (EP) friction in our cars. The reduction of these chemicals in supplied oils was based on the fact that phosphates reduce the effectiveness and eventually damage catalytic converters and introduce minute amounts of pollutants into our atmosphere.

This is another of those subjects abused for ‘bar stool b*llsh*t’ one-upmanship. Ignorance is the main problem. Particularly as trying to get any really useful information out of the manufacturers concerned.
PISTONS -Features for Maximum Performance
Created: July 02, 2001
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. Both combine to require a piston that is as stable as possible to maintain effective and consistent ring-seal performance.
Created: April 07, 2000
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.
Piston Fact File
Created: January 30, 2000
Over the years, there have probably been a dozen "stock" 1275 pistons. Currently, three different designs are available from AE/Hepolite as "stock" replacements. All have an 8.4cc dished top, but compression ratios are carried by changing pin height (Pin height is the distance from the top of the piston to the center of the wrist pin- see dimension "A" shown here).
