A Nitto stroker kit will acquire it out to 3.2ltr, and Spool Have a very package to head to a massive three.4ltr, building the RB a real torque monster.
Certainly, behind each and every wonderful engineering feat could be the story of battle, perseverance, and fervour, and it’s no diverse On the check here subject of RB and JZ engines.
