As the standard connecting rods cannot withstand a power increase from 500 hp, we recommend using steel connecting rods. From a boost pressure of 2 bar, reinforced TURBO piston pins must be used (see below). These are already included in the Ultras Series.

FSR piston:
The asymmetrical FSR (Forged Side Relief) piston line from JE Pistons includes a modern forged design with a wider piston skirt on the main pressure side and a smaller, friction-reducing skirt on the secondary pressure side. Combined with precise CNC machining, the result is a high-strength, lightweight piston that is extremely durable.

Ultra Series:
The Ultra Series piston combines all the premium features of JE and the brand new technology of the forging industry!
JE's revolutionary Perfect Skirt coating is one of the many technologically advanced aspects of the Ultra Series. It protects the piston skirts, reduces friction and prevents cold start piston slap and false knock.
All Ultra Series piston are supplied with a ceramic crown coating as standard to guarantee longer life and better exhaust cleaning properties.
Thicker piston pins made from premium material are another feature of the Ultra Series.
Combined with the unique Grain Flow Optimised forging technology, the Ultra Series is ready for tremendous performance.
