FYI....don't know if any of you have heard of this. I was skeptical at first, but thought I'd try it out since it had a 30 money back guarantee.

I went here and bought one for my 97 civic ex. I installed one along w/ a K&N Airfilter and saw my mpg increase by 5.5. I also bought one for my 94 F-150. I haven't evualated it yet since the price of gas has been over $3 per gal, and it cost me nearly $100 to fill it up.... The turbonator is $69.95, and they have one that will fit all makes and models. Food for thought...
