currently all the 2.0 and 2.3 5 spd manual tranmissions in the US Mazda 3 share the same ratios - both gear ratios and final drive ratios are the same. The 5spd manual trans is identical on both the 2.0 and 2.3. In some other countries such as Japan they do have a different final drive for the 5spd manual it is 4.388 in the JDM models. The US models have a 4.105 final drive. Again this info only applies to 5 spd manual transmissions.
