Alright I guess I should get a build thread going so I can document everything and have a place to ask questions and get advice along the way.

I have an '07 aluminum block 5.3 (L33) with 243 heads. Picked up the engine locally. Story is that it was a dealership pull out due to engine noise, I believe they put a new cam and I believe lifters on it and didn't solve the problem so they gave the guy a new engine. I was planning on doing a simple rebuild on any engine I picked up regardless, so as long as there's no internal damage I should be good to go. I also just picked up a Borg Warner S400SX3 (S471) 71mm T4 1.10 A/R. This is my first turbo build so it'll be a bit of a learning experience as well. I know several people locally that have 5.3/S475 combos and I've seen what they run and how reliable they are so for the most part I'm planning on copying those builds.

The car this will be going into is my 1991 Camaro Z28. The goal is to make a minimum of 600whp. It's going to primarily be a weekend street car that will see a lot of roll racing and some track time on the road course with a few passes at the drag strip here and there.

Here's a quick run down of what I've come up with so far.

ENGINE:
Aluminum 5.3
New rod/main/cam bearings
ARP head studs
ARP rod bolts
Aftermarket rockers
Aftermarket valve springs
LS2/6 intake
New rings regapped
Corvette accessories
4th gen F-body oil pan
80lb injectors
Dual in tank Walbro 255's

TURBO:
Borg Warner S400SX3 71mm 1.10 A/R T4 177248
Custom ETS intercooler 22" x 12" x 3.5" with 2.5" inlet/outlet
Twin 38mm or single 50mm wastegate
Single 50mm blow off valve

Now all this is definitely not set in stone. The only parts I have so far and the complete engine, turbo and intercooler. So any advice is more than welcome.

I'm subscribed. I'm waiting to see what everyone else is using for wastegates and BOVs on their 5.3.
Going to be a good looking car with something to back it up. What are your plans as far as keeping the body straight following this build?
