Now what I want to do is go a step beyond that. Something like: lower volume fuel injectors, more restricted intake, freer flowing exhaust, etc. Any trick that will possibly increase the gas mileage, I'd like to know about it. I'm looking for bragging rights here, so cost not a huge factor. Even crazy conceptual ideas are welcome. I'm looking to surpass 40 mpg (which I know is possible), but I want as much as possible. Let me know guys, thanks!

This probably belongs better to the fuel economy forum, but anyway, here goes.
Whatever you do, don't detune your car. It just doesn't make sense.
First, clear your trunk of any crap. If you are brave enough, trade your spare for a tire sealant/air compressor combo.
Continuing this weight reduction effort, get some light alloys. Kosei K1 TS in 14" would be perfect. For this purpose, do not upsize.
Make your way to cleanmpg.com and learn some skills. Changing the way you drive has by far the most impact on your mileage. Buy a trip computer like Scangauge. You need its instant feedback to properly execute some techniques detailed therein.
Then you can mod your car to set it up for economy. People at cleanmpg now advocates pumping your tires to the sidewall max, not placard pressure. So instead of 32psi, you pump it to 44psi if that's what the tire says on its sidewall it can take. Run synthetic fluids in your engine and tranny.
Other mods done for gas mileage include grille block - use something to block off the holes in your bumper. Partly done for aerodynamics (idk about that) and partly done for faster warmup in winter. 9th gen Corollas have a little plastic baffle ahead of the front wheels; you'll want to see if you can add that.
Others have also tried adding an underfloor pan for a flat underside, again for aerodynamics.
One of the more extreme mods I've heard recently is to use a deep cycle battery and add a manual cutoff on the alternator.
Don't try this one yet though, it's not proven yet.
Beyond that, it's time to read cleanmpg and ecomodder. Good luck.
I'm aiming for about the same numbers
