convert 911 3.2L to 4.2L?
--------------------------------------------------------------------------------
I have a 2004 911 4S (996) with a cracked cylinder. I am having the engine rebuilt by an outfit in LA called Vision Motors. They have asked if I would like to bore it out, put in chromoly sleeves and up the displacement to 4.0L or 4.2L.
Question: Is this a good idea? Will the rest of the car be able to handle the extra HP? Should I upgrade the oil cooler or add a performance clutch? How about the deep oil sump?
Any thoughts or advice would be appreciated
