Scope of delivery: - original Garrett GTX4088R 825614-2Description: With us you get an original Garrett turbocharger. We obtain these from Garrett distributors, so you can be sure that the turbos are original. Garrett is one of the few turbocharger manufacturers that subjects the turbos to several qualification tests, which means you always get a top product. Among other things, a 1000-hour durability test is carried out on an engine in a Garrett engineering laboratory, thrust bearing tests, the maximum tolerance of the bearing system is checked, as well as material fatigue, a vibration test is carried out, etc.The Garrett GT and GTX series are all double ball bearing mounted, finely balanced and oil- and water-cooled. There is also the older generation T series, which are mostly plain bearing. The GTX series differs from the normal GT in that it has a special, larger compressor wheel with several blades, which results in more power and slightly better response. It is important with the ball-bearing turbochargers that they do not get too much oil pressure. For this reason, an oil restrictor with a 0.9 mm bore is used for the oil inlet. In comparison, a ball-bearing turbo responds approx. 400-500 rpm earlier than a plain bearing turbo. When choosing the right turbocharger, please ask us or check the manufacturer's website directly at http://turbobygarrett.com/turbobygarrett/turbochargers.
