Wössner forged piston kit Renault F7R turbo conversion

Low-compression kit for a suitably prepared F7R turbo conversion. The standard F7R is naturally aspirated: this kit alone is not a complete turbo conversion. All three 82.7 / 83 / 84 mm bores are documented by the manufacturer and offered by Daluz. The historical manufacturer catalogue lists a nominal 8.5:1 configuration at the standard bore; the 2025 catalogue lists 8.74:1 at 84 mm. Check the actual oversize compression ratio against the machining, cylinder head and engine build. Manufacturer application: Clio Williams and Mégane F7R 2.0 16V, 1994 to 2003.

93 mm stroke, 21 mm piston pin, 30.7 mm compression height and 144 mm rod centre distance.

Check the engine code, actual bore, machining and clearances with the engine builder before ordering. Dimensions alone do not guarantee fitment. Image for reference only. Detailed accessory contents are not confirmed.
