My stage one came with a .81 A/R exhaust.
What turbo does this housing fit? I was wondering if maybe HP used different brand turbos as often as different sized exhaust housings. Mine is a 60mm Holset.
1979 Mustang coupe, EFI 393, A/A intercooled Eaton m122, 4r70w trans, Megasquirt II, T-top swapped in.
1990 Mustang, 545 BBF, C-4 with brake, ladder bars, tunnel ram with two Predator carbs, solid roller cam, 9", 390/45r15 drag radials.
