March 21, 201313 yr I picked up a 2005 with a rod knock. Not bad but needs to be rebuilt. Found a 2006 with only 58K on it, It was not cheap but with only 58,000 miles I went for it. When I pulled the old motor and had it next to the new one the differences became clear. The Drivers side head has an extra sensor on it, the exhaust is different.... I think I'm leaning to selling or finding a car that needs the 2006 and getting the 2005 rebuilt. Thoughts?
March 21, 201313 yr 06 into 05 should be good to go - what vehicles did they come out of and which one had the sensor on the head? do they both have VVT? i'd swap the 2005 intake manifold onto the 2006 and run it. if it's VVT differences, you can install a VVT engine into a non-VVT vehicle, it just won't use the VVT stuff. can't go the other way that i'm aware of though - put a non-VVT engine into a VVT vehicle. you could always swap heads too, then install the better turbo headgaskets to boot.
March 21, 201313 yr Author I suspect the 2006 is VVT and the 2005 is not. The 2005 has the standard dual port y pipe and cats, the 2006 has the O2 sensors and cats under the engine. Should have done more research! Live and learn. Thanks Larry
March 21, 201313 yr all can be converted to work though. use the 05 heads on the 06 block and change the oil pan/pickup tube
