well..i'd say if you got enough, you should put a K20A in it instead of finding another jazz/fit engine. we got a few for sale here in new zealand on nzhondas.com

i could also ask another guy for you for the price of one, i think they got one in their workshop or something...he said they can put it in my jazz if i m seriously wanting it, but i dont think i'll be in near future..so yea..gimme a pm if interested. other wise, check out http://www.tau-net.co.jp often, you might find something you want there, quite cheap some of them, around NZ$2300 for one.
