Are you going to replace the engine with a 3.4 from the 911?

If so, then you need not be concerned about the sleeved engine fiasco that affected a number of '99' Boxsters.

However, if you intend to keep the current engine, then the build date on your car or knowledge of whether the original engine has been replaced would been an inportant consideration. The sleeved engine deal affected cars produced in the 10/98--2/99 time frame. Those dates are not precise, but fairly close.

Essentially, there was a deviation from standard motor assembly because the block supplier had breakdown in their machinery, forcing Porsche to use blocks that had previously been rejected for quality problems. The blocks were bored and manually sleeved; unfortuneately, the process was not error free and a number of the engines built this way failed as the sleeves slipped in the block.

Also, what mods were you thinking of?I know some have gone with a different intake, headers and exhaust but not sure of what the HP increase is out of those mods.
