good 5.3 build specs? here is what i have planned out for now it will be a while before i start buying but i wanted to know everyones take on what i have in mind for this project
i have not found a car yet but i think im gonna pick up a v6 camaro or mustang that i can find on ebay or craigslist for cheap
anyway here's what i have in mind so far(keep in mind i plan to do all this for less than 4000)
2002 L59 with 79k for 375
Zo6 cam 117
50# injectors 300
LS6 valve springs 55
t-70 600 sorry its small
PCM 90 (will get dyno tuned)
snow H2O/METH kit 275
total so far - 1807
should i keep the truck manifold or switch to an LS2
what do i have to do to bolt a TH350 up to it
how big of converter do i need for this cam
where can i get some good flanges to build my own headers (or a kit)
what BOV and wastegate should i use and how big
how much boost can this combo handle safely i planned on running around 15lbs
i plan on doing a dyno tune when its all done

Ditch this: vision motorworks 80mm throttle body 115
Match the outlet on the turbo's compressor. The air is being compressed and forced through the throttle body, whereas being pulled in by the engine, shrinking the cross sectional area needed to avoid choke flow.

Think of an engine as an air pump. To get air in, in has to suck against every component in the intake (intake manifold, throttle body/blade, air filter). The main reason why a larger throttle body on an NA engine boosts power is because it lowers the restrictions, allowing more air to get in, making more power.
When forcing air, any type of pumping loss is not present any more. The air is being forced through the intake system and into the chamber. The general rule of thumb on a turbo car is to make your intake piping and throttle body equal or greater to what the outlet on the turbo compressor is.
There is only so much air you can flow through an opening before a restriction becomes present, that point is known as choke flow. If I recall correctly, its roughly mach 1.
Sure can,

The truck intake is supposed to flow as good as an ls6 intake (which is better than an LS2, proven to over 1000hp).
The TH350 will bolt up, minus 1 bolt (don't even worry about it) all you need is a flexplate and a spacer from GM. (very similar to this thread https://ls1tech.com/forums/automatic-transmission/155531-going-th400-special-parts-my-ass.html)
Converter - what are your goals? street or strip?
As far as flanges and stuff, check out the sticky in this section on Truck manifolds (probably came with your longblock).
BOV and Wastegate - it depends on who you talk too....some say go cheap with ebay, and some say go with expensive stuff....
do a search on "5.3 turbo" and you will find lots of builds, one of em dynoed at 717rwhp thru an auto!!!
Not on roller cams. Parish used a completely stock longblock, minus cam and springs and injetors. He used the truck intake, rod bolts, etc, etc.

thanks for your help

As for converter, your best bet is to call a reputable converter company. Try to find one that has experience with turbos, as they need to be loose on the bottom, but couple really well on the big end.
