Plastic engine

from wiki:

the Cosworth engine

This engine, based upon the Cosworth BDA, tipped the scales at 168 lbs, half the weight of its metal counterpart. Plastic parts included the engine block, cam cover, air intake trumpets, intake valve stems, piston skirts and wrist pins, connecting rods, oil scraper piston rings, tappets, valve spring retainers and timing gears.

The plastic Cosworth engine was raced over two seasons. It was raced in a T616 HU04 and competed in the International Motor Sports Association's (IMSA) Camel GT Championship in the Camel Lights (Group C2) category in 1984 and 1985. The car's best finish was a third in class at the 1985 Road America 500

I didn't know about that plastic engine, but have heard about composite materials used in the oil sump and valve covers. But once I heard about a ceramic engine which was developed by Porsche...

Yeah, I vaguely recall something about ceramic pistons or cylinders, but everything else being plastic.

Some folks already dislike plastic intake manifolds, I wonder how they would react to an all-plastic engine...
