Run the BW 80.

I know how big it is but I didn't cut my frame to fit mine. Still on the stock K-member too.

It will be ok on a 4.8L, but its still a tiny turbine side to be moving a big 76mm compressor wheel.

Yeah that's why i stated that I'm rear mounted. Even a front mounted 76mm on a 4.8 W/ .96 housing seems like it would bee to Laggy and oversized In my opinion, depending on his power goals and setup.

Freeman is running twin 70s on his...both front mounted on a 5.3. We will see how it goes. I really don't see a single .96 front mount spooling any later than 3500 rpms. It is not a big turbine or turbine housing.

What are the specs on the on3 turbine wheel? Are they any better flowing than the turbonetics 76? Cause I know the tc units have back pressure issues even tho the housing is a .96 ar the wheels its self didn't flow.

I just got the .81 housing on yesterday. I like making boost at 3000rpm i thought lag wouldn't suck but after finishing my build i realized lag sucks. I know a 76mm ain't big but if i were doing a 4.8 i would do a 70mm just to reduce lag and still make good power.

i had the on3 70mm with the .68 exhaust side on my turbo 302 before the LS swap....full spool by 3200 rpm and continued to pull until 6k.....no shaft play or anything after a year of use and 15 psi regularly....

now i have purchased an Ebay GT45 that alot of folks on TTF are using....the 4.8 will spool it just fine
