Not too familiar with these engines but here is a question for anyone here who knows. When using either of these engines in the mountains do they require some adjustment to run well from low to high elevation and backup again? If it is like a gas motor how do you correct it for the change in elevation?
Not to be a smart fellow, but do you have mountains in Texas? Just kidding, being a diesel I believe you won't have to do a thing. I've never had a problem running a diesel engine up to 5 or 6 thousand feet anyway. Someone else with more experience will chime in soon I'm sure.
I don't do much mountain driving either, but a turbo should make up for the low pressure/o2.
My job allows me to move all over the country as I please and I had been thinking of moving back to Colorado. Since I haven't been to pleased with my SBC I was thinking of going with one of these diesels since I wouldn't have to change up alot to make them bolt up. I hadn't figured they would be much of a problem up to Denver but I would be traveling back and forth from the high country. As far as the turbo goes I wasn't aware that they came with them.
With the diesel being fuel injected I don't know if you would need to worry about hieght all that much.
It is a mechanical injection though Joe. It is set up for sea level, 59 degrees F and clean #2 fuel.
The 6.5 with the turbo will acclimate better to altitude if that is your question. Then you just need bigger intake tubing, exhaust and anything else you can do to get more air into and out of the engine.
Well that helps to decide which of the two but I've read that the 6.2 has cold start problems in those climates, does it affect the 6.5 equally as much?
