Default 5.3 Turbo Build

Okay guys so I am fairly new to the LS motor but I came from the traditional SBC motors. So I need advice on building my 5.3 to be a turbo motor. I paid $400 for the motor out of a 05 truck that was wrecked at 65,xxx miles. It has 862 heads, I'd like to keep everything as cost effective as it can be. I have a Holset H1C, can easily get my hands on a HX35, and S475's are everywhere around here. What turbos would you guys reccomend? What about cam and head set ups for turbo? It is going to be put in a 85 Z28 for a drag car so there is my intention so you guys have an idea of what I need. So let me know what you guys would do in my situation.

S475. Stock heads. Look around for a turbo cam. There are a million of them out there so it's a bit hard to just point and say "that one there".

Okay so what do I need to look for in a cam to match the S475? And should any porting be done to the heads or leave completely stock?

Also I have the chance to buy a brand new Edelbrock Vic Jr. fuel injection intake, low profile 90 degree elbow, and fuel rails in all matching black for $450. Is it worth it for the turbo setup I'm going for?

I'm on my phone so it's hard to see the pic but it looks like it's the edlebrock low profile one. Correct? If so that elbow doesn't perform that well compared to the 90 degree version.

the s475 is a great choice if you can get it for a good price only other thing i would do is buy some headstuds from arp for your 5.3 just for added security and make sure to get proper oiling to the turbo and you are golden

pretty sweet set up on the intake for 400 bucks you cant beat it if its a budget thing that intake should be fine unless your aiming for crazy numbers previous poster is right about the elbow but no harm in running this one

Yeah S475's are everywhere around here. We run them on all the diesel's around here. I'm trying to keep it on a budget too since I still have to finish my Camaro. I also was going to ask about the head studs. Thanks for help guys.

Why the 317 vs the 862?

Keep your 862 heads, add some springs, get some China head studs (there are threads on here proving their value), Headgasket and you are golden.

The whole 317 heads thing on a 5.3 has been discussed but no clear answer. Yes allow for more cc's but people also say that using them makes the setup a dog off boost. I would just use your stock heads.

Because the ching chang head studs are ~$100 and pretty well proven.
