Engine Management Talk

[JDMFantasy2k]

Well i'm trying to learn as much as i can about honda engines and turbos because i've decided that eventually i'd like to A. Build my own engine (based on 2ndgenteg's ideas in the how-to forum) and B. Turbo it. So far i've found that Hondata is worshiped as the best engine tuning device to ever be created, but what are some (temporary) alternatives?

Basically, after i build an engine (or have work done to it) what do i need to make it run, and then eventually to turbo it.
I know this is a huge open ended question, but any input, or description on what some of you are running would be helpful so i can get an idea of what to do eventually.

Also i'm assuming dyno tuning is a must. Thing is, i know of a dyno facility, however i think they only do HP runs and not actual tuning. Would i be able to tune it myself using a dyno? well any help would be apprecieated.
