Picked up a cheap S13 but I can't stand the look of the front seats, they scream econobox. sadly they are a side mount seat rather than a bottom mount so I have no clue what seat I can swap in to : a. improve looks b. improve comfort c. increase holding capacity in turns ;)
Just musing here, but the RX-8 has a bunch of pretty nice seat choices and you can pick them up sometimes for not too much on their forums. They're narrow enough they should fit most applications with custom brackets. Also, the Speed3 has some nice seats.

Check out this article on the old SCC Project Silvia. It goes over some of the issues you will have fitting an aftermarket seat to an S13:

I am pretty sure Skyline seats bolt in to S13s, or you could get one of the cheaper reclinable buckets on the market. I think Horsepower Freaks has the Sparco Steel model seats on sale for around $200, at least according to the promotional e-mail I just received from them.
