Critique my build plan

5.3 block

forged 3.905 wiseco pistons
forged 6.125 rods
stock crank
rollmaster double roller timing chain
LS1 intake,TB
custom cam(dont have one spec'd out yet)
317 heads.
stock rockers w/trunion upgrade

TURBO system plans

truck manifold's, or headers
2.5" primary tubes
garrett 76mm .70 compressor a/r .96 exhaust a/r t4 flange
3" downpipe
a-a intercooler
turbosmart(or other manufatcturer) 45mm wastegate
^^ blowoff

my goal is maybe around 700hp on motor with maybe 12-14psi

do you guys think i should use this turbo or go slightly bigger? headwork?

any suggestions are welcome, i have lots of pitures of the turbo. its a street car.

i was basing my build off of hot rod mags 594hp 5.3 turbo build.

Headwork is always worth while, and an LS6 intake would be better

That's a really small cam. I think it would work great. Did on my 5.7. 5.3 is not that much smaller.

ok so headwork maybe if i can swing the $$

and it will be a 347

and i just cannot justify spending 300-400$ on an LS6 intake. i know it would be better but i can so spend that money in other places.

thanks guys.

any thoughts on the turbo and supporting components?

are you opposed to going with a different turbo? aside from that, focus on **** it keep it together and not making more power. i'd keep your list exactly as is.

what i mean by that is spending money on durability and not power, ie : ls1 intake over ls6, etc.

but yah that turbo should make 700 at the crank no problem, i'd be a little worried about the A/R on the EX side though, what size is the turbine wheel?
