Yup, if you can get it out in one piece, that is definitly easier. I just took out my tranny yesterday to install a LW flywheel and race clutch, and it was a pita to get at all the torx bolts ... took about 4hrs to get it out (boy I sure wish I had a lift!)
To make your like even easier, remove the whole front end clip (bumper, rad, nose piece, etc.) It only takes about 1 hr to do, and will save you the hassle of trying to tilt the engine up out of the bay.
