I would recommend making sure all the maintenance is caught up and it's in mechanically good condition before modifying.

Once that's taken care of, I/H/E is not a bad place to start.
i would have to agree with that, id check out the timing belt etc. If you put all your money into mods, and then something like that happens its sucks trust me. :(

Of course the maintenance is the first thing to do when owning any car.

When you do start modifying it, do tires/suspension first. You will see the biggest changes in your car overall by upgrading how it handles. It will accelerate and brake better too, and of course look better when it's not jacked up like a 4x4. Tires first, then shocks, then springs, if you don't do shocks and springs together (which saves work/time). Also remember to get an alignment when you're done. You will probably also want to replace the old bushings with poly or with new rubber if they are beat (they probably are). Start working on making more power when you can put it all down.

In addition to suspension, do the braking system too. Make sure that the MC and the lines and the calipers are in good shape. Decide if you want to stick with the rear drums or pull rear disks off a 90-91 si or integra.

Everyone here is always tlakign about making bigger power numbers and i think we lose sight of the fact that a stock d16a6 on a sweet suspension is already really really fun, as well as economical. Take your time with the mods, it'll be more fun for you for longer and it'll be easier on the pocketbook.

Just my two cents.

Ah, I forgot about the brakes. If you have an Si already though, just stick with the stock setup, it's plenty for the CRX. Of course make sure everything is in good shape, clean new fluid, good pads and rotors, and a good MC. Rear disc isn't really necessary, it just looks cooler and is easier to work on. Your braking is going to be ultimately limited by the tires though, and suspension plays a part too (when the car dives forward and unloads the rear, the rears lock up faster).

One thing that always bothers me is that people think more power requires bigger/better brakes. A 2100lb car with 200hp slows down just the same as a 2100lb car with 100hp. If you want improved feel, swap the MC or the booster for a bigger one, or get stainless lines.
The best braking EF I've driven, by far, was my friend's gutted hatch. OEM blank rotors with HP+ pads, prelude 15/16 master cylinder. He also had a rear disc conversion because he wanted to use the teg rear end so he could install a rear sway bar.

Pretty good advice!

I had that thought today while i had my Crx out.
Even in stock form, it's still a snotty little car & it is still fun to drive! :D

tune it up forst. . . . all new filters, oil change, gas air. . . .stuff like that. . .then change the timing belt and water pump. . . .. might be a good idea to drizzle some fresh solder on the main relay too just incase. ..

then i would start off with an intake and free flowing exhaust. . .

make it relaible first though. . . . .brakes, front end parts stuff like that. . . .
then worry about the performance mods. .
