well there are lot more difference then you say there are between the NSX and the NSX type R. Any honda vehicle which has the Type R badge other then the ones that ppl put themselves
are track ready cars. With chassis stiffening and modification to the suspension and engine tweaks for better power delievery, light weight, better gear ratios, brakes and all. It is like having a modified car. So the badge Type R does not only mean better engine, like in the Civic and Integra, it means a whole better package of performance from the factory. The Type R mods were done by Mugen up until a few years back when they seperated and now it is Done by HFP(Honda Factory Performance) but the know how is still from Mugen, Becauze Mugen is Sone of Honda afterall
