Thought this may be a good idea for others as well, to explain what certain things on the z20let engine do. I'm sure people will know what some bits do, but not others.. so may be a worthwhile thread!
so would be good to list the number, and then the part name, then its function, and then people can add or ammend what others put, sort of in this style:
Image Number 1
1: Part Name
3: Anything else?
p.s hope members dont mind me using their pics
and if anyones got anymore time etc to pick any other parts, may also be useful:
