Forged pistons are an important part of any powerful engine. They are able to handle a lot more power than the original cast Renault items and are available in varying compression ratios according to requirements (Standard Renault Compression Ratio = 11:1).
For the Clio 2 RS 172/182 F4R engine we have both high and low compression sets available. High compression pistons include 11.8 : 1 and 12.8 : 1 and are for use in high power normally aspirated engines whereas low compression pistons (8.5:1) are for use in forced induction applications such as turbo charged or supercharged conversions. The pistons come in a set of four and are supplied complete with gudgeon pins and piston rings. They are available in the standard 82.7 mm bore size, 83 mm or 84mm (11.8:1 and 12.8:1 only) overbore sizes.
We have regularly seen close to 400bhp with the low compression pistons when using our turbo kits and up to 250bhp with the high compression pistons when used in a high spec normally aspirated engine build.
