Generally 2.5L SVT engine will not last as long as a standard 2.5L engine. These engines have bad/cheap rod design. SVT engines with higher compression put more of a stress on the rods causing them to fail.... If you do a rebuild get new aftermarket rods...
Many have said that these engines oil pumps cavitat when taking sharp turns, etc. Actaully from what I have heard on testing, it is plain and simple rod failure....not to mention cheap torque to yield bolts.....
3.0 rods are a little stronger and don't have the same problem as 2.5l engines from what I have heard.....
