Probably not. Tbh it's not like there's only a very subtle difference between the two cars: A quick look under the bonnet would have told you what engine it had, or even (although this isn't infallible) a glance at the bonnet itself! Actually, scratch both of those, looking at the rev counter should've told you depending on if it went to 7K or 7.5K rpms. You knew enough about the different revisions to want the 313 model, yet didn't think to check that it was one before you paid your money? Sorry bud, but I can't be the only one here thinking that this is a problem entirely of your making, and unless it was mis-sold as a 313bhp model (which I bet it wasn't if it came via a Nissan dealer, as they tend not to put things like that on their adverts) then I'd just suck it up and put it down to a mistake you're not likely to make again.
