    4 2 1 exhaust lambda sensors

    I am fitting CG13 engine in a mini and have a question regarding the exhaust manifold. The standard manifold has a O2 sensor before the cat and another after the cat. As I will not have a cat I was going to put one sensor in primary pipes 3 and the other in the final pipe (once I have welded a...

    Help with my mini engine conversion

    Thanks for that Matt. More questions - 1 Where does the small hose on the throttle body go to? 2. Could I use it for the fuel pressure regulator (as it looks like that is the only vacuum line I will need)? 3. Where does the breather on the left I welded a plate with three 1/4 BSP holes in it...

    Help with my mini engine conversion

    This is my first post on here but been here many times and found help on most occasions. I am fitting a 1.3 K11 into a 1974 mini. I am about year into the build but unfortunately lost my build thread on 16v mini forum due to an error by the Web hoster 123.com. Now I have a problem that I...
