This will be my first attempt at building a 6.5 turbo. Here is what I got. I have a blown 6.5 turbo in a 95 Sub K1500. Mains got cooked due to an oil pressure fluctuation, probably a bad or plugged oil pump. I believe that the top end has been worked on extensively, I see new gaskets and such on the upper intake manifolds and everything. IP looks to be pretty recent, already has new PMD kit remounted at the firewall. Turbo checked, bearings look good on it. I also have a 6.5 non-turbo engine out of my 86 K5 Blazer, running w/ about 115,000 on it, I think my injectors may have just started to get tired on it but otherwise very reliable running and great steady oil pressure at about 40 psi, didn't use oil, never overheated, always started right up even in cold single digit weather. My thought was to do the following before using this engine:
-replace rod and main crank bearings
-new piston rings
-new oil pump
-new timing chain and gears
-take heads to shop for cleaning, pressure test and milling if needed
I wasn't going to replace the cam, cam bearings, or lifters, don't really see a need for that. I also understand that these engines were prone to overheat, so I intend to do the 97-99 cooling upgrade with the 130 gpm water pump and the dual thermostats. I will be using the injectors out of the Sub, like I said I think the top end and fuel was worked on pretty extensively not too long ago.
Just a note, I haven't tore down either engine yet. I don't know what the non turbo looks like inside just yet, I will update as soon as I am able to take a peep.
Tell me whether I am doing the right thing. I want to drop this baby in and not have any issues with it down the road as I intend to keep the Sub as long or longer than I kept the K5 (10+ years). Any help will be greatly appreciated. Thanks a lot.
