I have my 2003 3.2L M96.24 engine completely torn down due to a "gentle" IMS failure, no other engine damage. I've replaced the main bearings, thrust bearing , rod bearings (what the heck, I'm in there anyway) had the heads re-worked and am starting to rebuild the engine from the ground up.
I found a stock IMS with bearing on E-bay (very hard to find) and am using it over the dealer part to avoid the oversized IMS bearing issue. I'm going to go with the LN bearing after completing the rebuild as the clutch is still good.
The engine had 120K at failure, all the journal bearings were shot, but everything else is in amazingly good shape.
What performance mods / upgrades / part replacements would you put into the engine if you were rebuilding from scratch?
