Minor update. Today I finished the engine. As you can see, I have added plug wires to it. The wires are from an old USB cable. Hoepfully it looks OK this time and not too oversize.
I was having so much fun building this engine. It really is a shame that I have to put it in the engine room now and some of the details will be gone forever...
Notice I have added some major weathering on it to reflect the milage that Ryosuke has put into his car...
