Subject: Automatic/Standard engine differences

   Date: (none)



I was browsing thru the Miata Brochure, and noticed that the Automatic

engine is rated at 105 Horsepower. After looking further I noticed that

the reason for this was apparently a lower compression ratio (9.0 vs

9.4) and a lower timing advance (8 vs 10).. Question: How does mazda

achieve the lower compression ratio? Headgasket, different cylinder

head? Also, are there any differences in engine block design for the

Automatic. Ie. Does the block have the provisions to change to a

standard tranny backed engine?



I'm still trying to find a way to cheaply  convert my 93

Auto to a stick >
