swap or turbo
I have a 00 Silverado 4.8L, 192k Miles on engine and transmission, currently has a intake and high flow filter, flowmaster muffler, vette servo (soon to be installed). Still runs great though. I have driven other trucks with only 100k and didnt run this well.
Now I have the option of picking up a 5.3 complete w/ wire harness uncut, fuse box, and ECU with 130k miles for $500. Should I drop the $500 into the 5.3 or turbo the 4.8? I am looking for a little more power as its my DD truck.
Let me know what everyone thinks

I have little experience with turbos and cars, but nothing when it comes to turbos and trucks
Only thing that scares me is the higher mileage of my current 4.8, I have no idea what the mileage range is on these. Any insight on the mileage factor?

IF it has good oil pressure i wouldnt worry about it.. 192k aint nothing for one if its been half way taken care of.
Its not like the internals get magically weaker at a certain mileage. But it might have a lil more blow by.
I wouldnt hesitate to turbo it.
Theres guys gettin 250k mile junkyard 4.8 and 5.3s and pushing them hard with 20# boost.
Good Fuel and a good Tune is the key

Right now the oil pressure is around 60-70psi at like 3000rpms. at idle its around 40psi. I never see the needle go below 40psi for oil pressure (factory gauge). Is the factory oil pressure gauge accurate, or should I hook up a aftermarket one?
I am thinking I will go through Blackbear for a tune.
As for doing the rebuild like rings and bearings, that is a little hard. I rather have a spare long block if I am doing that then the truck is still driveable.

The stock 4L60E has the same mileage, Do you think I should look into rebuilding it or just put the vette servo, shift kit, and deep pan in and call it a day? I know the older 4L60Es (OBS) had issues with the sunshell and burning up clutches (i went through three OEM ones).
