I believe I read somewhere BL makes an adapter to make the 4bolt convert to a vband so the tial wastegates can be used..If so anybody with that combo or have most just hacked the flange off and welded on a vband?
Hack it off, add a piece of small reinforcement bar to be safe depending on how big or heavy your wastegate is and you'll be fine, using an adapter is fine but it's somewhat uncessary and just adds another piece to the already compliated puzzle should something leak.
burns stainless doesnt sell v-band flanges for wastegates. if he is running a certain wastegate he should run that wastegates vband flange which should come with the wastegate. he wasnt inquiring about vband's in general he was wondering where to get the v-band flange for his wastegate. if he would have followed your misleading advice he would have been sent in the wrong direction.
