My friend is building an evo motor thats about 10 times smaller than that. fully functional w/ crank, cams, valves etc and all the correct ports. around the size of my thumb. I'll get him to post pics some time..

man that's small. So he's essentially using a 3d printer to make a mock evo?
 
only for the head. he's machined the rest.

center lock spindles w/threads (messed up)

"I had to grind a carbide tool to a perfect razor sharp point to cut the threads since they are only .0025" (.01mm) deep. The thread pitch is .2mm on a diameter of .080" (2.03mm)."

It's essentially a tube chassis DTM car ( whole chassis will be hand made from brass ( was done once, then changed, currently built w/ plastic until everything is done). Will have double A-arm suspension etc

/thread jack - sorry
