Don't see why I couldn't be done? I would think with some research and some diligent tractor junkyard scavenging you could find a similar sized engine with a turbo on it and fab manifolds.

The question is do you really need any more power? Are you doing things with this tractor that are loading it down to the point that the motor bogs noticeably? Also is the rest of the tractor going to be happy having extra power put through it?

Disregard that if your just thinking to use a turbo along the lines of smoke reduction.

With that said even those things wouldn't stop me! NEVER have TOO much HP just too little traction.

 

No i am not bogging it down or really need the extra horse power,I just thought it would be cool and the extra HP's would be nice as you stated,i'll look into it

 

Check the forum "ihcubcadet.com" There's a couple guys there who have put turbo's from an old 650 cc Yamaha motorcycle on their diesel Cub Cadet's. I think the model name was a "Seka" They don't get a lot of boost with their 60 cid diesel's but they do get some..... I've heard 4-5 psi.
