If you want to have a reliable turbo LS engine that will live up to abuse then I would suggest replacing the pistons at a minimum and even the rods for the insurance. Sure there are plenty of builds out there where they take a 100% completely stock LS and throw huge lbs of boost at them and they make insane power. How long do you think that is going to last in a real world vehicle?
I also have plans to put a turbo on my 85 with a 6.0l swap in it but I am going to replace at least the rods and pistons and possibly the crank if I want a little more CI. Your prices seem to about right but don't forget about tuning. That will make or break the whole project. Like mentioned earlier, ls1tech has alot of good information on boosted LS applications. Good luck with your build and plz keep us updated bc I would really love to see this. Not too many turbo'd classic trucks out there.
