is it possible to modify reprap Mendel to have a build envelope of 230 mm x 200 mm x 140 mm, something like 9'' x 8'' x 5.5''?

One approach, assuming you have not cut your threaded rod yet, is to simply extend the dimmensions.

If the machine is already built, you can trim the Y-Axis bottom sheet from 140mm down to 110mm. The mail limit on the Z-Axis is the extruder bumping into the Bars up there. There are a few ways to creatively get those out of the way. That should give you another inch or so that you can move in Z. If you need more space on Z, consider using shorter screws on the print bed.

With either solution you will need to modify your firmware, and print software settings too.

I had the same question too.... Where are those parameters in the firmware? I have a custom RepStrap with a bit larger print area than a Mendel.

Yes, firmware. Look in the configure.h file.
