Hi !

my firts post

i preparing a parts list to drop a ls egine in a g body
for 90 % steet application


i will go with a ls 6.0 liter 2007 lq4
with stock head and piston for now
i will go with bigger head and came later

the turbo will be a gt4718R ball bearing

the .96 a/r on T6 exhaust housing.... it's too small ?

the stock fuel line dia. 3/8 pss and 5/16 returning it will do the job ?

stock LS fuel rail will be ok ?

i alredy have a dual intank walbro 255 second pump
turn on 10 psi to late ? to soon ?

i will go with a 4" single shot exhaust... is a
hooker aero chamber will do the job ?

can i ridding it without ls9 head gasket and stud with
that turbo under 15 psi ?

thanks for help and excuse my english

.96 a/r isn't too small, could go bigger but it will be fine. Never used stock fuel system with high power so can't say for sure. Definitely don't use a chambered muffler.

Why no chambered muffler? I am new to FI building as well. I have most of my plans laid out already but I have not heard about this in my research. I'm going to procharge though and I am currently running the GMMG chambered cat-back.

With a turbo, any backpressure post turbo is a bad thing. Not nearly as big of a deal with a blower.
