Our GTX4508R Series turbos are manufactured specifically with a combination of the highest quality components and exquisite design with no expense spared! The dual ceramic ball bearing design provides an optimal turbo response and prolongs the lifespan of your turbo. Our GTX45 series turbos are fitted with an 11-blade point milled billet aluminium compressor wheel with an aerodynamic tapered tip secured inside an aluminium compressor housing, and fitted with a sensor port. Our compressor wheels are designed with the latest engineering that maximizes horsepower and boost response and are also temperature rated up to 200°C. Each turbo is fitted with an anti-surge ported-shroud compressor inlet to increase surge resistance and provides reliable, continuous power. The turbine wheel is manufactured from Inconel which is a high quality super alloy and does a fantastic job at maintaining strength at high operating temperatures of up to 900°C. Our turbine housings are made from a high grade cast iron providing ultimate durability in these high performance applications. Turbine housing options are available with a T4 or T6 inlet single scroll. Each and every turbo are supplied with all the required parts such as stainless steel polished v-band clamps, flanges, water fittings, turbo drain gasket and NPT 1/4" to -4AN turbo oil feed fitting with 1.6mm restrictor hole.
