MPG with a turbo Gen 3 truck?
I'm doing some research for my current swap, a Gen 3 V8 into my 1998 Durango (originally a 5.9 Mopar Magnum) as to what engine to buy for the swap. I figured this would be a great place to get some real life experiences from those with a gen 3 turbo.
I'm rebuilding a 4L80 due to the weight (about 5100 #) of the truck, and for when I may do some towing with it. The truck has 3.92 diffs and is 4WD. I am leaning towards buying a 2003-04 LM4 (aluminum block 5.3) out of a Trailblazer due to local availability along with low cost and weight but am still open to other options (4.8 or 6.0). Since I'll be commuting in the truck 60 miles a day, I want to build it for decent MPG. Unlike my prior car swaps, I'm not as interested in going fast. ;)
There seems to be some debate over MPGs for NA vs turbo trucks, so I thought I'd ask here for anyone that has some real life numbers for a turbo truck.
I'd like to get the following data:
Year/model of truck
Engine size & mods (such as cam, heads, injectors, single/twin turbo, etc)
MPG city/highway or average
Thanks for any input.
