Good point

I kind of meant of manifold's etc, but rest assured if I somehow trash the motor and it needs taken down there will be full pic's
the post was rushed and didn't quite read the way it should. The English/auto site is the only place that I have seen the central injection refered to so far and its not mentioned anywhere on the car or in the owners manual that I can find so far.
So far we know different crank and pistons plus central injection that no one knows what it is??
