Are you talking about an engine swap? Or doing a tear-down and rebuild on your existing 3.2? You can easily do a 3.2 to 3.4 conversion on this motor without machining the spigots. Cost of 3.4 pistons and cylinders...about $4100.00. You also can do a 3.5 and 3.7 liter conversion for alot more money and there as alot of machine work that needs to be done on the case, not to mention rods. I just spoke to Peter at Andial and he indicated to me that the cost of doing a 3.7 liter motor correctly would run somewhere around $25,000.00!! Heck it's only money.
If you do a search, you find alot on this topic.
