I do not remember how the sedan gear ratios compare to the CRX ones, but I do know that there are three different five-speed transmissions that were used in the 88-91 US-spec CRXes.

The transmissions from the "DX" (or "standard") model and those from the Si model had the same individual gear ratios, but the final drive (the ring and pinion ratio) was shorter in the Si, so effectively all of the gears are shorter.

The HF (I think I remember that there were two different versions with slightly different gearing) used taller gears and a taller final drive, so all of the gearing was much taller.

Here is a web page that lists out the different ratios. I believe you divide the gear ratio by the final drive to get the overall effective gear.
