I assume the problem is warpage from heat? Otherwise I would think Mazda would have considered going to aluminum, or more people would have done it.

coast is the major factor with them, that and the plating one needs too put on them.

why would you want aluminum? For weight?

The enigne is like the lightest engine there is in any sports car already.

just for fun, does anyone have any pics of a fully functional motor using the racing beat housings? i've heard people talk about them i don't know how many times, but have never seen them used.

They use them on aeroplane engines mostly.

And they arent as durable as cast iron ones.
