Our Turbochargers are engineered with the best materials and fine craftsmanship to ensure they conform to our standards of excellence. Our turbochargers are machined and assembled with high dimensional accuracy, resulting in better performance and higher durability. Our compressor wheels are made of 354 heat treated aluminum alloy; a much denser material that allows for a more precise balancing over conventional wheels. The 354 alloy wheels can withstand higher operating temperatures and higher rotational speeds for superb engine performance.
