PRODUCT DESCRIPTION
Powerful JR.Spec external wastegate with a 54 mm diameter piston. This allows for use in high-horsepower vehicles with turbochargers lacking an integrated wastegate (e.g., Holset HX35, KKK27, etc.). The kit includes a second spring, which greatly facilitates its adjustment for a specific boost level. The valve is very robustly manufactured, with durability and build quality superior to other valves available in this price range, matching the quality of original parts. An additional advantage is the V-band connection (included in the set), which greatly facilitates its assembly and disassembly, eliminating the problem of bending flanges, sanding, and loosening nuts, as was the case with conventional wastegates. The valve features a polished stainless steel body which, unlike the cast iron sold in other auctions, does not deform when the piston jams. This deformation often leads to overboost and damage to the turbine or engine!
Wastegate color: blue
