I have a stainless ebay manifold that i wanna use, made for an FD (single turbo set up, so i'm assuming its T4 flange).



But the Flange for the manifold doesnt match up with my stock S5 hitachi.



Correct me if i'm wrong... but i belieive its a standard T3 flange size on the hitachi ht-18s?

if so, then all i need is T3 to T4 adapter flange.



thanks

the FC turbo has its own flange. its neither t3 or t4.
