ok im building my first mani and its a divided t4 setup and i want to run two 44mm wastegates but was just looking on bmcrace's site and didnt see 44m, just 40 and 46. so can you guys help me out and explain to me which one to get, or if there is a 44mm flange available elsewhere that i should get??

 

Full-race.com or atpturbo.com

 

i get them from ATP. they are $20 each as opposed to $35 from full race.

 

i forgot to mention that i need mild steel. do any of you guys know if either one of these two companies will make a mild version or if any one else sells one already in mild.

 

why do they need to be mild steel?

 

you might not want to get a mild steel v band flange, it will rust and youll lose a good surface to seal with.

 

C Jack don't act like you know

 

will it be alright to weld the stainless ones to a mild steel header if so what filler rod do i need to use. also i was going to get the header ceramic powder coated to take care of the rust

 

its fine to weld stainless to mild. most manifold are stainless with mild flanges

you would use 309L for stainless to mild welds.
