18Hp Briggs in a Terra-Tiger?

[AllisCowboy87]

Hello, I'm wondering how much trouble it would/is going to be to put this 18hp opposed cyl. engine in my now 10hp TT. I want to go to the 4-stroke so I can crawl around in the woods and pull some hillls. And the electric start would be nice too! Thanks for your input. -Wes

Hi, Welcome to the Forum.
If your going from 2-stroke to 4-stroke, you need to change your Drive clutch and change the spring in the driven clutch (on the tranny.) Not sure how much room there is for a larger engine on a Terra Tiger, I think it's relatively tight, but you can probably squeeze it in. Of course you'll need a new engine mount and to wire up the new engine correctly.
