truck is a 94 s10 ex cab AWD. motor is an 02 LQ4

so far i have done a complete rebuild on the motor.
ARP Rod Bolts,
ARP head studs
Felpro permatorque MLS Headgaskets
Perfect Circle Rings
Ls7 Lifters
Comp springs good to .620 lift
chromoly 7.400 pushrods
Ported 317's w/ valve job
as well as all new gaskets, seals etc..

fuel system i have is
-aeromotive stealth in tank pump
-8an feed/-6an return lines
-aeromotive canister fuel filter

i have a BIG FMIC w/ 3in piping,
HKS SSQV Blow off valve
Tial 44mm Wastegate

i have a 9.5 in 3400 stall convertor also, stage 3 65e, 3,73 gears all wheel drive

here come the questions what turbo has been proven the best i know mpt70 is a good choice but ive seen good things from the s475 also i dont mind pushing the limits of this motor i want to see what i can do but i want to find a happy medium where it will last awile. ive seen power numbers from 450 to 700 if i could make 600 id be very happy but i know its probably a far reach.

so here are my 3 main questions
-best turbo for spool time and power (i dont want to spin the stock rods up past 6800)
-Best size injectors for the power range (i was thinking 60#)(running stock truck intake +rails right now)
-best cam (off the shelf) for pump gas (93) for boost but a good power range and quick spool up

S475.
I would just do 80s, they're not that much more and fuel is good.
Speed Inc. TU1 or a ZR1 Cam.

ya kinda had my heart set on the s475 anyways i miss my last one lol. 80's are prolly the way to go because it leaves room to grow for pretty much the same price and ill check out those cams. you think my power goals are realistic?

also which of these two s475's is ideal i used to have the 1.32 AR but it was on an older big block so idk..

im thinking the 1.10 AR will yeild a better spool time am i correct?

96x87 w/ 1.1 exh for only 600hp, should go to 8-900 but a 75mm compressor won't support it on those heads very well. Need an 80-83mm for that much power.
Won't support a lot of RPM on a 6.0 either.
The 83x74 is better suited to a 5.3.

TU1 or LS6

80's if you want room

Are you planning on doing your trans every year or two??? AWD w/V8's and an 60E don't last.
Start saving for a 4L80E and an adapter from RPM/Boost Depot.

i work at a trans shop i have 2 spare units at all times lol i like 60's because of the lighter convertor and less static HP loss due to the lighter internal parts those 80e's are monsters. so im gonna grab the 80# injectors, and the TU1 cam am i maybe better off with twin mpt70's? im honestly thinking grabbing two cheap ebay turbos to get it dialed in and then swapping to better units.

what are my options for twins? could i piece together some junkyard turbos? hx35's perhaps to keep costs down? i defiantely want a setup as least capable of over 600 wheel horsepower though so when i upgrade the motor later i dont have to redo my whole turbo setup

only thing that sucks is its 900 bucks lol but its borg warner so the lifespan is pretty much gonna outlast everything else

EDIT

two of these perhaps?

Just bought that on3 76mm journal turbo about a month ago. Heard nothing but great things from that company. The turbo looks really nice and should make great power. Even jegs sells their stang kits so they gotta be pretty reputable

I would probably do twin t70's with .68 ar if I were you. Twin 76's might be a little over kill
