So pistons (higher CR? Or just forged?), cam (just one?), flywheel (steel I guess, as aluminum is forbidden), exhaust system (including manifold?), airbox and Magnetti Marelli for engine and gearbox. Supposed to be drivable unit!
R1 has standard engine with ECU to improve midrange... Also some nice bits in the suspension...
Twingo Renaultsport R2:
Features the normally-aspirated 1,598cc 16-valve K4M RS engine developed by Renault Sport Technologies, ensuring the car is effective, reliable and fun-to-drive. The main changes concern the pistons, camshaft, flywheel, exhaust system and the addition of a specific air box. This special preparation gives the engine an extra 27hp compared with the production model, reaching a mighty 160hp (118kW) of power at 7,250rpm. Maximum torque (160Nm) is reached at 5,500rpm. A specific motorsport ECU manages engine (power supply and ignition) and gearbox operations. It operates in conjunction with a special electrical wiring loom and may be combined with an optional data logging. Twingo Renaultsport R2's engine has been designed to cover 2,500 kilometres of special stages between each service.
Twingo Renaultsport R1:
The engine and gearbox are identical to the production model. An ECU setting giving torque at lower engine speeds will be homologated to improve mid-range performance.
