95 valve springs (left) are stiffer compared to 99+. Starting with the 3/95 start of the ODB-II implementation (VIN 14193) the pistons were changed with a slight dome to increase the compression ratio to an actual 9.0:1. The ’94-3/95 pistons were factory rated at 9.0:1 but actually was around 8.8.
What kind of engine does a Mazda Miata have?
99-00 pistons produce 9.5:1 compression through a raised dome in the middle.

It was advertised as having 155 hp but in reality only had 142 hp because of US emissions tuning.
