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.

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...

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.

Did you know a detailed engine increases the resale value of your car? It's a well-known fact that people who take the time and effort to detail their engines also take better care of their cars.

Only engines bearing a 12CC engine no. prefix were painted in British Motor Corporation Engine Green (the color somewhere between sage green and olive green applied to the power units in most BMC motor vehicles, including all the Sprite and Midget variants prior to 1967). This equates to roughly the first year of 1275 production.

Watch Our Video - If you've got too much slack in your A-Series engine timing chain, Mini Mania now has Rollmaster timing gear sets in stock to take up that slack! These oversized gear sets come in three offset options.

This is another of those subjects that crops up on the message board frequently. I am constantly surprised by the number of engine builders - or people who charge other folk for building engines at any rate - that never hand out such an information sheet. It seems pretty daft to me that having taken a wad of money off of a customer for an engine you've lovingly put together, you'd want to help that person get the very best out of the engine.

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.

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.

Essential to the well being of every engine is its oil pump and oil. Much in the same way as the heart and blood is deemed relatively important to us humans! It’s also another of those greatly misunderstood and, unfortunately, misrepresented subjects connected to engines.

Small piston applications and availability have been changing over time
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.

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).
