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 and copper) the piston achieves a high temperature tolerance value meaning its deformation at high temperature is minimal.

The Supertech N18 MINI Piston is supplied in a variatey of sizes to suit the needs of the engine. For example, if a bore is required due to scoring, the oversized version 77.5 mm is available and compression ratio options are availble to suit MINI Cooper S or JCW or for tuning purposes.

The pistons are also available in different compression ratios as follows:

  • 10:1 for the N18 JCW engine
  • 10.5:1 for the N18 Cooper S engine
  • The 10:1 compression ratio can be installed into the Cooper S N18 also it is advisable to couple this with an 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 should I install Supertech forged pistons?

Forged pistons provide a stronger alternative to the standard piston found in the N18 Cooper S and JCW engine. The increased strength allows for a more durable engine and one that allows engine tuning to be pushed further in a safer manner.
