164,000 mile 4.8 with turbo?
Hey guys, I was wondering how many miles would be too high to add a turbo. Im torn between spending the money on a low mileage 00-06 sierra/silverado or a high mileage truck for a turbo. If i got the high mileage truck, I'd do the turbo and plan to do a complete rebuild in a year or 2 down the road. I just found a truck for a good price with 164,000 miles, and assuming that everything was sound on the engine, what would you think about adding a turbo?
Also originally planned on getting a 2wd and lowering it 4/6, but now I'm toying with getting a 4wd and lowering it. Temptations....any opinions/suggestions would be greatly appreciated.

Yea thats kind of how I was leanining too. I think a turbo, lowered 4wd would be great, but its more weight, more moving parts, more money, more issues lol.
And just a question out of curiosity, does anyone know how much boost a stock 4.8 can take before detonation occurs on 91-93 pump gas and without using meth. I know its affected by the cam, and IATs, and a bunch of other factors, but I was just kind of curious what the typical limit was for boost in a stock 4.8. THANKS

Do it !
The original 5.3 in my truck had 183 k on it , the lifters took a dump when I cammed it, but it ran great and still had factory cross hatching on the cylinder walls !
So my advice is change the lifters if you put a cam in a high mileage engine , other than that you should be good , and like said you can find engines for around 500$ .
He'll my LQ4 van has 230k and runs awesome!
