New to forum, intend buying a clio of some version, so seemed a good place to ask.On paper the 172 cup seems the best in terms that its the lightest, & would make a good basis to tune.If Im missing something or theres a better basic vehicle to start with let me know.Im assuming that you can uprate the stock 172 engine to a similar output for a given spec.as any of the other more powerfull versions.
