I recently purchased a classic Mini which has been fitted with a 1.4L Vauxhall motor on an AllSpeed subframe. I'm trying to find out what year the motor is so I can purchase replacement parts for it. The motor appears to be a C14SE, but I'm not certain. I don't know what the motor came out of. Is there a chart I can use to reference the motor serial number to find out what year it was produced? Same for the tranamission. It has a 5speed trans but I'm not sure what it came out of. Thanks for any assistance you can provide.
