How do you tell what kind of crx you got?

Answer 1

HF - 1.5L MPFI engine, also an 8 valve engine. It makes around 65hp, and averages right around 60 mpg. HF's are sometimes the most popular for someone looking to do an engine swap because they are the lightest of all three models. Funny part is some of that lightness comes from the engine and the rest comes from the front hubs and the hatch. Well once people swap the engine in an HF they normally put different hubs on too, so in reality they could have jgotten a DX and took the wiper assembly out of the hatch and basically that would be the same idea. The hf model basically has two options, A/C, and tap deck.

DX (STD) - 1.5L DPFI engine, 16 valve engine that produces around 89hp, rated for 38mpg. DX's have DPFI (dual point fuel injection) which is basically an advanced TBI (throttle body injection) and it works just like a carb but instead of jets you have two injectors firing, plus the crank sensors along with other sensors it is much more efficient than a carb. You could get a DX with an automatic 4spd, or a Manual 5spd. I can't remember for sure but I think there were two final drive ratios used in the DX 3.89 and a 3.93. Basically you have the same options as above, tape deck and a/c.

SI - 1.6L DPFI engine, 16 valve engine that produces 108 hp (some people say that the A6 in the SI models have a slightly different cam profile and make 113hp, but no one is for sure as far as I know). The SI came with 5spd only, also its list of standard equipment that the HF or DX does not have include; power sun roof, recaro seats, rear swaybar, rear disc (90-91 models only) 14" aluminum wheels, gas charged shocks, front air dam, as well as other things that I can't remember. Final drive ratio on an SI was 4.20.
