Hey guys its my first post on here. Ive had this truck for about 6 months now and ive been buying and collecting parts. Im gonna have questions to the more experienced guys. Thanks. As of now i have nnbs intake, milled .030 799 heads, btr stage 1 turbo cam, callies rods with arp bolts, 4l80e swapped, duratrac with 4.10s, yukon 1541h axles. Im sure im forgetting stuff 1st day i got it

 

I was originally going with the basic on3 turbo kit but i got a free s475 t6 turbo from a family member. So now im gonna get me a trick hot side kit. Do yall think the turbo is too big for the 5.3? I havent got pistons yet. I dont know which ones would be better for my build. I might be going e85 since i have a gas station less than a mile away from me. Lol. Im looking for at least 700hp.

 

Thats a pretty big turbo for a 5.3. What a/r is it? Why are you doing pistons? Being a 01, I guess thats not a flex fuel truck is it? I am planning on doing a flex fuel sensor so I can take advantage of E85 when I want to.
