manifold issue...help!!
i recently bought a bmc log manifold that has the old style 4 bolt 44mm wastegate flange. for one the only wastegates i have seen that are 44mm are vband. second of all i think 44mm wastegate is overkill for a setup that im planning on only making 275whp max. what i was thinking is getting a 38mm flange like you would for making a dumptube and cut the 44mm flange off the manifold and weld the 38mm in its place. i think it would work but would like some input or advice from you guys. thanks in advance

Re: manifold issue...help!!
i thought it would to i just wanted to get another opinion before u hack the old flange off. i just hope that the 38mm flange leaves enough room for the existing pipe to weld onto it that was my worry

You can, but the 44mm is a little big of a pipe for the 38mm.
Why not just dig around and find an old 44mm or rather just cut the flange off and have a 44mm vband welded on? It's never a bad thing to go bigger with the wastegate...

i know the 44mm is big but i dont think would matter for my setup as long as the flange could weld up.
i have tried searching for 44mm and most are vband which isnt bad i could weld on a vband but the wastegates are so much more expensive than a 38mm and i was trying to keep it a budget setup.

Your best bet is to either ditch the manifold and get one that fits your needs or find an old 44mm with the 4 bolt flange.
Going up in size is easy, you just drill out a bigger hole and go. Going down is a problem, because you have to fill the hole, and you really shouldn't just weld a 38mm 2 bolt because it will be a pretty nasty choke.
