Manley's H-Beam Rods for the Mazdaspeed MZR DISI engine are a great starting point for reinforcing your Mazdaspeed 3 or 6 with forged internals without breaking the bank. The H Beam can take a beating with a high torque and high horsepower setup up to about 500-600 horsepower and torque. Each rod is matched very closely to each other in weight so that the rotating assemble is closely balanced. Each rod is precisely machined to exact tolerances specifically for the Mazdaspeed engine.
