i was just wondering if it's possible to upgrade turbine housing and wheel? I have a brand new 7868 turbonetics "benita" Bbb and I'm a little concerned with back pressure issues with the .68 exhaust side . Any way to go to a 7875 setup or similar ? Pretty new to the turbo game , and as I already have this and continue to receive mixed opinions, I thought I'd see if it was possible and what combination would work best ?

They used to make a bigger a/r housing around a 1.3x something but it has been discontinued but it was stupid expensive anyways. Is your a/r housing really a .68 or do you have the .96 a/r housing. It will be cast somewhere into the exhaust housing what size it is. The turbo works great on 4.8 and 5.3s and even the bigger engines if you keep boost low. Very quick spool but it will max around 600-700 rwhp so keep the cam very small.

A/r .96 exhaust wheel is a .68

I just assumed if you went with a bigger wheel you'd have to have a bigger housing as well.

Treadstone has the larger exhaust housings for the F168mm wheel found on the Hurricane (TC) series turbos. They have them up to 1.52a/r.
