Try to find a stock intake pipe and filter box. That will, likely help more than the smaller exhaust. Consider an LS transmission, I got mine off ebay very cheap. The ratios are better matched to your engine and better for economy, but sporty enough to still enjoy the car you have.
Sorry, I meant MPGuino. They're backlogged right now so there's no way to know when I'd get one if I donated today, and I don't know of any guides to building one.

I'd like to swap the tranny but it's not work I've ever done before. I'd need some more jacks. I'd like to get any LS tranny though.

As for intake vs exhaust, I was under the impression that restricting the intake was at best neutral on efficiency (and possibly bad), while a correctly sized exhaust could actually net efficiency gains. This is incorrect?

Thanks all!
