jimmyc the 10-12K is from VRT and include JWT twin turbos, built motor (pistons, rods, block redecked, rods, valve springs, cams, etc.), suspension upgrades, big brake kit, and tuning to around 500HP RWHP. I know that all of this must not be done with a turbo, but if you are going to do it don't go half ***. I also know that I don not have to have this much HP, but I bet it would be fun!!!! I am a HP junckie. I have had a mustang and camaro both high HP cars in the 400HP range. I got tiered of just the power and wanted more plushness. Now I miss the power and want another high HP car, but not a rattle trap. Figuered I would just do something with the G.

 

3.9 rear final drive and smaller, lighter rims with really sticky tires

 

I cant imagine what we would be at on the highway with that. I am already over 3000 rpms cruising on the highway at 75mph plus. Amazingly, I still get 25mpg in the 05X at this cruising speed - must be more efficent at speed that alot of engines - or running lean.
