I added the MSD Blaster coil and distributor to my car (no ignition module) and I did notice a decent kick in the ass... not too bad for only like $60 or whatever it cost for the parts. I say that it was a good investment, but I wouldnt go as far as changing the whole ignition, thats more suited for high-RPM. Might I add that my car is also running rather lean, being the fuel filter needs to be changed, I imagine with a little more fuel flow i'll feel the effects more.

Nology hotwires also give the car a little boost, but they're not really worth the $180 price tag. As I found out.
