High Pressue Wastegate Top for 35/38/44mm

Upgrade your wastegate top from a single small spring design to a top that can hold the large Tial springs and/or dual spring setup. Mostly for the low pressure 35mm wastegates, and some of the first run low pressure 38mm's. If you find yourself upgrading springs to 1 bar and above and have an old top this is a must. You can tell if have a newer style top by looking for the ring grove/bubble going around the circumfrence halfway up the side of the wastegate top as seen in this picture.
