There are differences and it is more powerful mate but most RR days guys with the JDM model made around 200-210 tops. To make maximum power they need the race stuff in japan.
It has JDM springs, valves, pistons and a smaller smaller cat, gear ratios and mapping along with a
different intake and exhaust manifolds.
This of course adds power but, as i said, is made to go with Japanese fuel. A KPRO will change it for Vpower and get around 230-240bhp
