I saw that this morning too, the Subaru’s AWD is a lot different than the F350 4x4 which is really 2x2. Combine that with choosing a better line and then your tire choices it’s the difference between needing tinted windows to hide your shame or being the hero...

Well, it’s 30* here freezing Fog and rain and the sun has set so black ice will be forming too. This morning the fog was freezing, and so thick you couldn’t see 10’ in front of you, combine that with the idiots that don’t turn their lights on and it was dangerous to be on the roads.

No worries. I’m the guy who took 9 months to swap injectors so don’t feel rushed on my account.

I’m slowly coming to the realization that I’m probably going to keep my stock turbo. I’m not interested in going over 30psi boost or in spending $1500 to “probably” clear up my smoke (plus the 38R is not rebuildable). I’ve already modified the compressor side and wonder if there’s something I can do to the turbine side to help. There’s not a lot of SOTP info out there so am curious on your before and after thoughts whenever it happens.

I’ve still got traction bars, leaf spring, relay boxes, and a stack of other projects before I consider pulling the turbo off.

I thought that increasing the exhaust housing size increases lag time thereby exacerbating the smoke issue?

I could easily be wrong in my assumptions as I have not delved far into housing swaps and van turbos based on my assumption.

To clarify my “smoke” issue: it is a lingering “puff” of haze if I jump on it in my non-performance tunes. I don’t want you guys to think I’m rolling coal everywhere. If I roll into the throttle there’s no smoke.
