Description

Description

Supertech pistons are forged from aluminium alloy for high performance and superior strength while maintaining low weight. Using a 4032 alloy (an aluminium alloy containing Silcon, nickel, magnesium & copper) the piston achieves a high temperature tolerance value meaning its deformation at high temperature is minimal. 

The Supertech N14 piston is supplied in a variatey of sizes to suit the needs of the engine i.e. if a bore is required due to scoring.

The pistons are also available in different compression ratios as follows:
10:1 for the N14 JCW engine
10.5:1 for the Cooper S engine
The 10:1 compression ratio can be installed into the Cooper S N14 also it is advisable to couple this ECU tune to ensure running and get the most out of the engine build. The piston is slightly shorter so there are no fouling issues when using the standard MINI camshaft. Other camshafts may require piston machining.

Why would you install Supertech forged pistons?

Forged pistons provide a stronger alternative to the standard piston found in the N14 Cooper S and JCW engine. The increased strength allows for a more durable engine and one that allows tuning to be pushed further iin a safer manner.


Please note: This kit includes a set of piston rings for each piston
