Description Extended Information Post A Question
The heights of power for the Honda CR-Z lie in it's engine limitations, most notably the strength of the OEM Connecting Rods. To address this issue HKS released a Forged Piston and Connecting Rod Kit. This kit was initially designed for the HKS GT7040 Super Charger kit but can also be paired with other forms of forced induction.
HKS was able to push their S/C kit to add a whopping 155 hp and 116 tq (lbf/ft) thanks to this kit. Similarly the Pistons and Rods are rated up to 336 ps and 43.78 kgf*m.
