seem to be a little high dont they?

not really. no gears in the rear end

Snarky sarcasm aside, I don't know whether the differential in the xB can be altered

Are you in the right chat room? XB's are front wheel drive.
They have no rear end. (Where is my a$$ at?)
You could change the rear end gears but you would have to add a rear end first.

I got my RPM's down by moving the needle in the tach, now I never go over 3000 rpm.


ORIGINAL SUBJECT LINE READ:
CHANGE GEARS IN THE REAR END TO BRING DOWN RPM's.

well swap transmissions with a toyota echo... or get an auto.

Or put some 35 inch wheels/tires on it.

J/K.....There's really no practical way, other than what hotbox05 said....neither which would be very cheap.

I'm sure you could get an Echo tranny for next to nothing from a junk yard. If you are mechanically inclined, you could swap trannys in a day... nothing too complex in removing the transmission.

Adding a taller tire would raise the gear ratio by a small degree.

And then you could rejoyce at your extra-sluggish acceleration...

As this member points out any raise in gear ratio will lower the power at take off.

echo trannies do not fit....diff mounting tabs.

you can get TRD final drive gears...
you can swap out the gears from an echo, not the whole tranny.

Taller tires is the cheap way..... slower off the line but less rev's overall

gear swap seems like the way.....

i got used to my high rpm's thats where my header likes it at

also gives you a reason to do all the other cool things in that dept...

light weight flywheel...
clutch...
LSD...
front sway (easier with the front end down...)
front braces...
