Also the same Qs for the SC46 Billet T.S.?
Hi,
all our original twin scrolls used the standard P25 housing machined to suit, I think they are around .63 A/R.
The housing was not big enough and the exchange issue was a bit messy so a new housing was cast, its slightly larger than the P25, not sure exactly by how much but it has allowed us to machine it big enough to create the new SC50 Billet twin scroll.
The range of SC Billet twin scrolls are a true twin scroll with twin volutes and twin waste-gate buttons, just need something to bolt them onto .
cheers
Kev
