(probably, but i have to ask!)
My little turbo project is meandering along nicely, but the wastegate on my gt1544 appears to close with vacuum. Now i'm assuming that as its off a vectra dinosaur burner, then it needs a 5psi wastegate from something else fitted to it? one that works the other way round. it stays shut till 5psi then opens....
Anyone know of a wastegate that will fit? like an oem one?
Also, how do you work out how much oil the turbo needs supplying to its chra?
TIA.
