I was not looking for more power but when the motor gives it up it may be an option to swap and get incredible mileage that's all. The power I will assume would be neck in next. Both engines are terribly underpowered. The 2.6 even more so IMO.

The 2.0L Mazda Diesel is a far better motor than the 2.6L Mitsubishi that's for sure. I own 2 of these diesels now and have owned them in the past and pushed 2 of them over 300,000 miles and they still ran well. I have yet to see a Mighty Max or D-50 with over 300K on the original motor and trans.

What are you basing 'they are a crappy motor' off of?

Also I am not saying I will for sure do this. I may go with a different motor like the diesel that pretty much can be put in this truck. I have seen a few of the conversions online and they looked like an interesting option.

The reason I started this topic was to get ideas and I am getting them. I also wanted to know if the motor like that in an escort diesel can even take the RPM's of the mighty max gearing?

I was wondering about the bell housing after you brought it up. Couldn't I just have a bell housing adapter made to blot between the original trans bell housing and the new motor instead of making an entirely new bell housing?

I am certain I have seen something like that before but I could be wrong?
