Tokicos aren't a lot better than OEM in my experience. I put on a set at around 95k miles and wasn't impressed. However, I installed AGXs up front 15,000 miles later, and they did make a noticable difference. This, on a '92 SE-R with stock springs.
It's nice to be able to drive to an autocross, dial the AGXs up to "4," and drive home on the "1" setting. The non-adjustable Tokicos are always set on "mediocre." With adjustablity and better dampening for not much more in price, the KYB AGX is the better value.
If you need any help with the installation, I can point you to some good posts in the SE-R List archives. Consider ordering some other bits (like rubber new springs seats, dust boots) before you start.
