I bought a 1997 Bobcat 331. It had a blown motor. Is there a better motor for it or should I stick with the V2203 Kubota that came in it? Will the V2203 DI unit work in the older 331's or should I just stay with the V2203? I read that there are Cali reefer units out there in good shape that had to be replaced due to emmission standards. Anyone know where I can get my hands on the Kubota 2203's that came out of the reefer units? I can use it in my state without issue.
