Re: 77 c10 5.3ls turbo

I did order a used piston/rod on ebay so I am going that route. I'll look into increasing the ring gap.

Re: 77 c10 5.3ls turbo

I am new here and this is the first time I have looked at your build. I am impressed at the thought put into this and workmanship. A few years ago I built a 73 Camaro with a single 91mm T6 turbo and a BBC. It took 2 years to complete and I had a WHOLE new respect for pipe fitters and fab work. It taught me how important it was to think ahead when fabbing. I believe I did everything at least 3 times before moving on to the next thing. ha ha

Your build gives me the urge to do a turbo in the 56 but I'm not sure I have the patience to do another.

Oh, I saw where you have a ring gland lift on a piston. If you know at what psi your were running win it let go, you may want to bump your waste gate down a couple psi. That normally happens when the ring gaps close and butt due to tight gaps using boost.

Re: 77 c10 5.3ls turbo

I never did summarize what changes I made with the most recent tear down. 1 used eBay piston and rod, eBay head studs, ls9 head gaskets, arp cam bolts, new lifters. Nothing to add more performance, just some small things for reliability (hopefully).
