I'm new, not to sure what to do on this site, so bear with me. I've got a 2006 Hummer H3, it has the 5 speed manual trans. V8, and allmost no gas mileage. Fun ride...

 

welcome to the forum... 2006ers were not available w/ the 5.3V8... did you do an engine swap? what other mods you thinking of doing?

 

And no V8 was EVER offered with a 5 speed either. You may have your information on your vehicle incorrect or you someone swapped in a V8 and manual trans????

 

I purchased it with a salvage title, it does have an engine swap from like a 2008 with 20k miles. a tractor-trailer ran over the front, everything has been fixed. I just plan on a 2/3 inch lift, and all/mud terrains with diffrent rims.

 

I'm sorry the paper work has the engine at 32k miles. NOT 20.
