Canada = domestic? I always thought domestic meant American...
Canada IS America, just not the united states.
I'm all about the 4bt. Or other 4cyl turbo diesels. In 2004 I had an '85 Pajero 4cyl TD (mitsubishi montero) while in Australia and it was fantastic. The thing I enjoyed most was putting it into 1st gear 4lo and letting out the clutch (yup it was a 5 spd) and crawling up sandy banks after crossing a river. All torque right from the get. Easy to manage power without high revs. Then you get the economy... I drove the entire east coast of Aus and averaged 34/36 mpg some hwy lots of dirt, fantastic. When I came home I was talking to buddy about putting a 4bt into a yj. Jeff beat me to it.
22k is expensive for an engine swap but it is worth it for a complete shakedown turnkey swap.
I had the opportunity to checkout Jeff's personal Bruiser 4bt while I was in FL. It is a beast. Though I wasn't able to take it off road you could tell the power was there. It's not fast but it was turned for economy and will go 75 all day long on 37's without breaking a sweat. It is awesome to feel the power at 1k rpm, the ability to pass on the hwy and still not have to run the rpm's above 3.5k. Easily controllable power that is usable without stressing the drivetrain. If you are going to EJS take the time to go check it out. It has made the short list for my JK once I've paid it off.
I did the math and at the current cost of diesel in CO it would take 13 years to pay back the cost of the conversion with fuel savings. That's if you run regular diesel, if you run waste veggie oil you'll pay yourself back even quicker. I have an 05 dodge 2500 with the 6.7L cummins with just over 50k miles on it and I only get 24mpg out of it when I'm not towing the horses.
Sorry for rambling. If you aren't sold on the 4bt cummins, Do find a 4cyl TD engine of someone's. The power vs weight and mpg is undeniably fantastic.
Does HPA have and vids of their jeep actually moving?
