Hi,

I am the owner of a '06 Corolla XRS. EcoMods to date:

ScanGauge
Light Motegi Traklite rims
205-55-16 (vs. stock 195-55-16) results in 1.77% taller gearing
tires inflated to 44psi
Mobil 1 synthetic
Lowered 1.2" from stock (XRS is already 1" lower than regular Corollas)
antenna replaced with "shark fin"
Vortekz VGs

My best mpg tank to date is 36.3 mpg with a lifetime (40% city / 60% hwy) average of 31.9mpg. (XRS new rating is 22/31mpg- old 26/34mpg) I've hit a wall; as this is the best I can do.

Admittedly, the Achilles heel of the XRS is its "sport" gearing. Even with my taller tires my engine revs at 2662 rpm at 60mph and 3106 rpm at 70mph. Way too high!

I would desperately like to swap out my 6th gear ratio from a 0.725 to 0.659 or so. This would reduce my rpms to 2420 and 2823 rpm at 60 and 70mph respectively.

As far as driving style is concerned, I shift early without lugging, and fight the temptation to use the 2ZZ engine's "lift" (@ 6,200rpm the Yamaha-designed engine switches cam profiles for more power).

Anyone know where I can find a 6th gear swap for the Toyota Corolla XRS?
Any other ideas as to how to improve fuel economy with my car?
Thanks in advance!
