i would like to change my 2.6L motor for a bigger but i want to keep my power train
is there a engine that would bolt on my trany ?

 

I can't say if there is an engine that will bolt to the existing trans for sure. It would not be a good idea anyway due to the fact that your powertrain is only rated for an X amount of horsepower. If you wanted to install a V6 or V8 for example that did fit your trans, you would most likely scatter the trans or differential all over the road.

You would need to have a custom job done to do what you want to do. Get ready to spend some $$$ if you really want it.
