The GT42 series from Garrett is just one of the many options you can find through Gillett Diesel Services. These turbos have dual ball bearing, oil and water-cooled CHRA. The turbine housing is a non-wastegated free float. The compressor housing is a ported shroud designed to increase surge resistance.
Diesel customers expect durability, reliability and, most importantly, power, and Gillett helps deliver by customizing turbos to their customers needs. This turbo can be used as a single or a compound. It can be low pressure or high pressure for higher horsepower. One important component to performance is in the ball bearing cartridge which is surrounded by a thin film of oil. The oil film damps out harmful vibrations that would otherwise compromise the durability of the turbo. Gillett Diesel offers a full service turbocharger rebuild and upgrade shop equipped with the latest equipment, including balancing services and an extensive inventory of turbochargers and upgrade parts.
