Super great post!!! I just have one correction. Hf did offer a rear wiper, right side mirror and clock. I have two Hf's both bone stock and one has these options and the other does not.
Clock and right side mirror were optional add on's that are installed fairly easy, either by dealer or special order, it was not standard on the HF. The rear wiper was not an option, if I recall, the HF does not have the wiring run for it from the factory.

For the 88-91 CRX SI: What are the different types of throttle bodies, and do they interchange?
I'm not sure what you're asking, they're all the same for the 88-91 Crx Si.
they are not quite all the same - the 88 had a different dashpot from the 89-91 with 2 vacuum nipples on it - this was because the 88 had firewall mounted dashpot control solenoid for controlling fast idle - 89-91 had a fast idle control valve on the back of the intake manifold, no solenoid on the firewall and the dashpot had only one vacuum connection - they do all bolt onto the manifold

I was not aware of that, Good catch!

-88/89 CRX's don't have side impact beams in the doors, the 90-91 do.
Is this backward? My 88 Si has impact beams in the doors. I tried adding 90-91 Civic door lock actuators but the beams are in the way. They must not be there in the sedan or they're out of the way. I didn't take note of them when I pulled the actuators.

Everything I have ever read AND seen supports this, 90-91 had the side impact beams.
Sounds dumb, but are you certain your car is an '88/has the correct door?
Pictures?

Good post. Not to be picky but my 89 hf has a clock and a passenger outside rear view mirror. I bought it in 1995 from my friend who bought it new. Also as I read in other posts, yes the 89 Hf HAS Vented front Brake Rotors.

I'm surprised no one has mentioned the steering racks. DX and HF had a standard steering rack(same rack for both models) while the si had a variable gear rack that was much easier to turn, almost like having power steering. Also my 90 dx had the smaller gas tank, sure wasn't 11 gals, I ran it completely empty and it took all of 9.5 gals to fill it up on more than 1 occasion as a teen and yes it was a factory original car bought from the original owner

I do not believe the Si rack was variable. I'm not sure it was different from the others, in fact.

Gas tank sizes can be difficult to gauge. Even if you stall from not enough fuel, there can still be a significant amount of fuel in the tank. (Depending on the shape of the tank; not sure about ours.) And the gauge is not exactly super accurate, it can read well over the "F" mark when the tank is full. And relying on the gas station's automatic cut-off is not necessarily that accurate either.

It's pretty well known the si had a variable rack, even has a VGR stamp on it and is a separate part # from the HF and DX which use the same rack, also why a quaife quick rack works with DX/ HF rack and not the si rack. I've driven all 3 models and owned Dx and si and there is most definitely a difference in the si, unless it had the rack replaced with a DX/HF rack. As for the gas tanks, I think someone screwed the pooch on the sizes as previously stated my DX would go from pushing into the gas station to overflowing in 9.5 gals, but my 91 si would take 10-10.5 not even getting to the bottom. I could be wrong on the tanks, but that's personal experience and not wikipedia
