I want to change my egine for a 4g63 (eclipse turbo engine) but I need to know if they use the same engine mounts or would I have to modify them to fit in the avenger engine bay? If I have to I'll put in the gs-t tranny as well, if it fits...Any help would be greatly appreciated!

Thanks guys!

 

The 4g63 mounts opposite side of the 420a engine. You are going to have to cut out the 420a engine mounts, and weld in the ones from the 4g63, among other things. Theres a lot of info on this site about it. It is possible to do and don't let people tell you it's too much work. If you have the money for the parts and are good with cars then id say go for it. Just make sure you find all the info first
