Stock 5.3 turbo build Hey new to forum.
only familiar with n/a old school motors so new to this area, im sure this has been covered before but either couldnt get search to work, probably doing something wrong.
im hoping someone could give me some info , pref from someone who has done something similar.
ive got a iron block 5.3 dead stock , runner , but condition unknown really.
putting on bigger injectors 1000cc im thinking .
1218 pac springs.
and borgwarner 76mm turbo
running e85 and air intercooler.
looking for info on what are the chances of this setup lasting long, on how much power ?? and if not what would be the first areas to improve on motor , or complete overhaul rings bearings machine work etc.
thanks

If you tune it right the motor will last nearly forever at any power level that any part of your drivetrain will handle. I take it back, your lug nuts might not break at a power level the motor will not handle.

driveline should be fine , and will a good intercooler setup just limit the safe tune hp limit ?? at the moment easiest is an avg air/air setup as the car isnt the best for room. could spend some more and go with a water setup (frozen boost) anygood ?

look onto Sloppy mechanics, they have done unless setups that make that power and not needing much. here is a quick plan for you
"acquire junkyard LS engine, leave it totally stock other than installing Pac1218 valvesprings and boost it, or install a turbo cam under .600 lift (limit of the pac1218s)install 80lb siemens deka injectors in stock intake, add 044 external or walbro400 internal fuel pump to vehicle (proven to support over 600whp so far by themselves)
3/8ths fuel line is fine, install any chinese 70-80mm turbo ($220-550, and 50-60mm wastegate $60-120)
use megasquirt or stock pcm and tune it or have someone tune it on pumpgas and methanol... wham 500-600whp"

76mm turbo is sized for more power for if or when I build a good motor. Already have
setup is all good gear minus engine.
Have the twin 044s with big cell for E85.
Coan Reid cased glide
Haltech dash and elite 2500
MW driveshaft
Got the air intercooler which I will try fit and see how we go it seems now.
Turbo smart 60mm gate and turbo smart bov.
also running a Moser engineering danas60;rear locker with 4.10gears.
No converter as yet
I would be happy with 500rwhp with nothing breaking for a while.

Every question you have has been asked and answered to death in multiple threads. Please get your search working.
4.10 for the 1/8, 3.55 for the 1/4. Do yourself a favor, pull the engine apart and gap/check the rings and clean all the **** out of the ring lands if there is any. Not the part you want to be lazy with. It can put an end to your season real quick. Do it now and be done with it.
Go to sloppymechanics on YouTube, you are welcome.
550- 600 is EASY these days with these engines. Follow Matt's formula get a good tune and it will live a long and happy life.
If you are gonna drive it or do 1/4 mile I would go with the lowest numerical gear possible. If it's just straight 1/8 mile car the 4.11 should work, id still prob drop it down some tho.
with that turbo and a well matched cam you should clear 500 wheel by like 12 psi, Maybe less. But it will go years like that with a proper tune. And I agree with above, gapping the rings and checking/ cleaning everything is good insurance.

4.10 is way too much. More power you have the less gear is needed. I'm at 1,000rwhp with. 3.39 and its still too much.
