Just to ask,what would be your ideas if you was making Enthusia?
For me,i would implement the ability to choose which part do you want to be installed in your car,for example,choose if you want to change the type of turbocharger in the turbo cars(Single Turbine,Twin Turbo,Smaller or bigger Turbos)and the method to reduce the lag(Antilag,Wastegate or 2-Step),in NA cars,choose if you want to increase the rpms,if you want to install a valve timing on the car,and to install a turbo or supercharger.
Another idea would be the implementation to change engines,like between LV10 cars,for example,install the Caterham Super7 engine on the AE86,The RB26 in the Silvia's or the Old Skyline's,the 13B on the Old Mazda cars,the NSX engine in the Civic/Integra TypeR,the EJ20/22 in the Young SS,and many others
