The car and engine look great!
I don't know if it is an optical illusion of the picture, but it looks like the top front wishbone are the wrong way around. If it is the same as on the Sierra chassis, the threaded tube should be pointing upwards, and on your picture, it looks like it is pointing downwards. Perhaps the wishbones' set-up on MX5 based chassis is different ?
If I'm wrong, please excuse my comment
