Kinugawa Tial Sport replacement wastegate springs are made from quality materials to ensure you get accurate boost controll. They are built to resist sagging over time that can occur with cheaper springs. Will work in genuine Tial 38mm gates, DPR gates, and a wide range of Tial replica gates. A range of pressures are available and large and small diameter springs can be combined for high boost applications (ie a 1.0 bar (large) and a 0.4 bar (small) run together will give 1.4 bar boost):
