Had a 82 Jeep Renegade with a 6 cyl. with a carb, and I don't remember if 4 or 5 speed. This thing ran great but loved gas, 14 mpg. I now have a 91 Wrangler with a 4 cyl., 5 speed and FI. This little motor has a lot of grunt. The mileage ranges from 14 to 20 depending on how i drive it. I understand the new six's are strong and the head design leaves a lot of options (12 port). These things come with a nice tube header...The 5 speed trans. looks just like a t-5
