Not only that, on a relatively stock motor, most OBD1 ECU's would likely slow it up more then make it fast, most of the programs out there are either meant for higher compression and more fuel, or for a specific cam setup.

Threr are some good stock programs out there, but you'll find your self re-chipping it in a matter of months when you do mods any way.

As far as ignition, the stock ignition is good to over 275whp, I wouldn't bother changing it unless you plan to spray or boost, and even then unless you plan to boost a lot, or spray a lot.

As far as cams go, you really need some sort of fuel and Vtec management in order for them to run normally if you get big cams, aside from that, you'll need to build your valve train. My thing is, if you have half the valve train apart to get to the cams, might as well do the rest, and do the springs and retainers.

With that $400, I would keep saving, and do it all at once, for like a grand, you should be able to get a set of cams, springs and retainers from Skunk2, which happens to be good, or, atleast, I must say, I've been quite happy with their stuff so far.
