how is your compression or oil pressure? on average while casual driving, for the 90 miata, it should be between 40 and 60...when you really get on it, it should be pushing past 60 and hit 70 then back off....around 3500 rpms in my miata is where the power really kicks in and that is where the car really takes off, however, it does not seem to have a loss in power under 3500 rpms....
