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.

Deves general Tips on Engine rebuilding
Created: November 21, 2005
To improve engine out-put, you need to increase the engine's 'breathing' ability. The stage one kit deals with all the easily bolted-on external parts, and represents the best increase for investment. From here on in the power increases will cost commensurately more money.

ENGINE - Reliability of the 1380
Created: December 12, 2002
I know I have taken pains to explain that you don't have to have a 1380cc with very sporty cam profile and so on to have a decent, satisfyingly quick road car - but this reliability problem is absolute hogwash.
Austin Mini Cooper Engines - 1098, Initial Tuning
Created: April 03, 2001
The 1098 (1100) engine has had a lot of bad press over the years - largely because of early experiences when trying to tune the motor brought about problems with the then standard components available - they simply were not up to taking any real punishment as experienced in racing.

Classic Austin Mini LUBRICATION - Oil pumps
Created: January 24, 2001
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.
Created: January 19, 2001
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.

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. 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.

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).
