1998 Dodge Dakota 6 cyl Two Wheel Drive Automatic

Is it possible to swap a '88 dodge Dakota 3.9L engine to a '98 dodge Dakota? Will exhaust align? Can I tap holes for my brackets for all accessories? Do they sell a kit of any sorts? I just need the block and heads from the '88 and plan to take '98 parts and put on '88 3.9L. Given any of the modifications, will it pass inspection with emissions?

If not, what other engines would interchange with a '98 Dakota 3.9L

Thanks in advance for the help

Tyler:
We only recommend direct fit parts. When you change from year to year, there are differences. You are jumping back 10 years. I understand what you are trying to do, and chances are it would work if you are able to attach all the sensors from your old motor. Yes the intake, injectors, vacuum, egr, wiring. Will need changed / adapted to work, but I can't guarantee that it will work.

As far as other years that would work, I don't have a cross reference. What I would suggest is contacting a salvage yard. They have all that info.

I wish I could be of more help.

I contacted a few and got mixed messages. Bottom line is it wont be easy and they of course have another motor to sell. I was hoping to exchange one I already have without to many more grey hairs but. Not sounding good.

Any other ideals would be great appreciated.

Like I said, we only recommend direct fit parts. However, you could make it work, but it will be a job. There were a lot of changes during those years. As far as the engine fitting and bolting in, there is no problem. It is everything else that needs changed. My biggest concern is that there is a location for a sensor on the original engine that doesn't exist on the replacement. At that point, problems start. Also, even if there is a place for sensors on the replacements, they may be different sizes, locations. Like you, I wouldn't want any more grey hair.
