The CRX HF has two options for gearing.. the final drive was longer if it's a non-cali model, something like 2.95, and 3.25 for california models.

Awhile back, I did a thing w/ a gear calculator to make the longest possible honda transmission that could actually be built.. I can't remember exactly what gears it used, but the 2.95 FD from the CRX HF wasn't an option, because it's a small bearing case, and the gears from the large bearing cases in the hydro models won't fit with it.

I'll see if I can find it the next time I fire up the old computer, I might still have the text file from it.

Also - the 88-91 has more than 3 5 speed trannys..

There are:
DX, LX, Si, HF cali, and HF 49, and EX (90-91 Only) For USDM

Then there are EDM and JDM and UKDM and AuDM options, which include the VT and VTi, GT and GTi (I think) and ZC models, and the Si-R. Each of which may have had it's own transmission as well.

The DX and LX for years have been touted as being the same, but they're not. The gears almost match up when you add in the FD, but they're all different.
