The TiAL WG38 Wastegate is manufactured in the US from the highest quality materials. The valves and valve housing are manufactured using 347 Stainless Steel Alloy. The 17-7 PH Stainless Steel actuator spring gives consistent pressure at high temperatures and will not "relax" at temperatures above 483 degrees celcius, unlike other wastegates on the market.

The Actuator diaphram is reinforced Nomex silicone also capable of high temperature operation. Weld on flanges are 12mm thick CNC machined. The kit comes standard with 0.7bar (10.29psi) boost pressure. The boost pressure can be adjusted by replacing the spring, and there are many different springs available to ensure the required boost pressure is met.

Wastegates are shipped with air fittings and stainless hardware, and each kit includes the wastegate assembly, a 38mm Valve seat, 2 faskets, 2 TiAL air fittings, 2 mounting bolts and 4 flex washers.

Flanges are included in the kit and also available separately. The wastegates are only available in highly polished aluminium finish.
