racer walsh sells alot of stuff, but mostly for carbed and/or turbo'd 2.3L's. i have bought from RW in the past and they are pretty good.
but truthfully, your first mod should be a turbo engine swap (yes thew whole motor and wiring harness out of a donar car...). easiest quickest way to get power out of your 4 banger. check out Reindeer's page, he has a ton of info on the 2.3L.

that's the correct addy, but his host is changing stuff around so it might not work right away...
you can get a turbo 4 banger to the 300 hp pretty quick easily.
