Who's running a turbo with .63 exhaust haousing?

[WILD_EYE]

I have heard many people say that a .48 exhaust is better for normal driving around and that a .63 housing is more for drag due to the turbo spooling later. At what rpm are your cars producing boost with .63 exhaust?

I have had both a .48 and a .63 ar exhaust housing. At the same boost level on a d16 I ran faster e.t.'s with the .48.

I would agree with that, but the .63 will produce more power in the long run. For autox or just a comfortable daily drive I would suggest the .48.
