Thinking this'd make a good comparison. because the stock M3 and NSX are equal with eachother in terms of performance. so these suped up versions of each car should be fairly similair too. the NSX Type-R still has 290 bhp, but it now does 0-60 in 4.4 secs (as tested in the august edition of british autocar) due to the introduction of new light weight materials etc. i'm guessing this car will have a further 0.5 secs taken off the 0-60 time of the stock M3, making it about 4.3-4.5 secs? i'd rather have the NSX tho, coz in my opinion it looks sportier (if not as aggressive), and probably handles better too.
