Turns the 2.5litre into 2.7 litre NITTO 4340 Billet Steel crankshafts are manufactured
from high quality true billet round bar stock. Most other
aftermarket crankshafts are manufactured using cast forged
material, which is a much cheaper manufacturing process
and hence carry a cheaper price tag but their performance,
strength and horsepower capabilities are significantly compromised
compared to that of a true billet crankshaft. An engine
with a 4340 billet steel crankshaft will rev faster and
cleaner due to the different harmonics produced from the
high grade material.
