Wow... another CT 240sx.... this being in the Turbo KA forum, and you saying you're going turbo, I assume you're trying to join the increasing number of KAt's in CTjust like this pair of zenki s14's:
Anyways, throught my years of edjimukayshun, I've found the best term papers/ essays to be the ones that prove at least one solid point. The thesis on "turbocharging a naturally aspirated engine" would be a peice of cake, where you could go over the positive and negative aspects of it, and determine from there if it's "good" or "bad", using your resources to prove each positive or negative point.
Anyways, I'm not an expert, but I have turbocharged my KA, and know quite a few people in person who have done the same, each going some different route. I could probably answer any Q you have about turbocharging systems, especially those pertaining to the KA24DE engine.
If you want to interview a professional, I'd imagine the best way to go about it would be to e-mail some companies like Turbonetics, Garret, or perhaps even some retailers like
http://www.turbochargers.com (there are literally hundreds of turbo retailers). You could probably even reach Corky Bell from
http://www.bellintercoolers.com.
Good luck with the project!!
P.S. A bunch of 240's will be at the first NER Solo II event in Ayer, MA. Check out
