Zero cost mods for 2AR-FE? Coolant bypass, etc
 

I bought a 2010 Camry SE yesterday. I am looking for quick, horsepower increasing mods. I have modded many cars - so are any of the following applicable to 2AR-FE?

1. Throttle body coolant bypass
2. Remove air cleaner silencer
3. Disable EGR (off-road use) ;)
4. 180 degree thermostat
5. Bored out Mass Air Flow sensor
6. Bigger throttle body
7. Aftermarket ECU (Predator, etc)

OK, I realize some of these are not "no-cost"...

thanks from John the Newbie

Might also check at the Toyotanation website, more members, more mods.
