I just priced a 6.5 Supercharged Chev Diesel April/14 from BULLET SUPERCHARGERS
The latest model Patrol that can have this engine is 7/2006 due to emissions.
P400 6.5Lt
4L80E AUTO
Total 46Grand! I almost fell over when he told me that.

For that money your better off going with a modern Duramax 6.6 it passes all emissions in later model cars
