I used to owned a 91 SIDEKICK, but "had" to sell it, and deeply regret it.......now I want to get a SAMURAI, and fix it to the max! but, the deal is that I want to go GREEN, so I think, if I can fit a DIESEL engine in it, and tranform it to BIO-DIESEL, that would make me (and willy nelson ) happy, but seriously; is there a diesel engine that would fit this rig? which one?
