Hey gang, I’m starting to buy parts for my turbo setup finally and wanted input from those in the know. Vehicle is 91 S-10 converted to full time awd with w/5.3 out of 06 Avalanche (cam, headers, tune, etc.) and built 4l70e/awd t-case from a tbss. Current cam is 219/224 .604/.609 115 LSA. Unknown rear/front gear ratio but based on driving I’m assuming 3.73/4.11 range.

Hoping for ~600awhp on (10-14 psi?) using 93 octane as there is no e85 available within 3-4 hours.

Here’s the list I’ve made and I’m hoping to get some input/thoughts/advice.

S400SX4 Turbo-75mm-T6-Twin Scroll-1.32 A/R (I’ve seen this a lot on the forum)

40mm Compgate

Turbo Smart 52mm race port

60lb injectors? Preferred brand?

A1000 w/boost referenced regulator

2 bar gm map

Cam I’m looking at is 226/231 .605"/.598" 113+4. Worth it?

Head studs w/ls9 gaskets

Biggest fmic I can fit (prefer not to use meth injection or air to water)

Truck manifolds? (space is tight especially on pass side with shock tower.
Plan is for turbo to sit pass side front with exhaust coming out pass fender)

2.5” crossover?

What spark plugs?

What converter? Will be mainly street driven and see the track occasionally. Looking at the Circle D GM 278mm HP 4L60 LS Torque Converter 2600-3200 stall.

I have a brand new iron front diff 7.25 ifs with 3.73s and I can’t decide if I want to change to 3.42’s or use 3.73’s. If I stick with 3.73s should I stick to a larger a/r like the 1.32 I’m looking at as I’m assuming it spool pretty quickly with 3.73s?

Any and all advice is much appreciated.

That turbine housing is huge for a 5.3.
Skip the 2 bar MAP and get the 3 bar.
Skip the A1000, they're junk.
Your current cam is fine.

I agree with JoeNova on the housing, I think I'd want a T4 for your goals

No need for studs at that level, new stock bolts will work fine and are cheap.

2" or 2 1/4" crossover would work better in my opinion

Good info on spark plugs here - https://sites.google.com/site/sloppy...ls/spark-plugs

Agree as said above. 2.25 or 2.5" tube is plenty with room to grow.
Everyone uses the 60# Siemens Deka and are cake to tune.
Truck manifolds or any stock manifold will work fine based on what you can fit in the engine bay
Id run BR7EF non-projected tip plugs
Run a better torque converter like Yank or other, seen too many mixed reviews about the Circle D stuff.

Okay perfect. Thanks for the help guys. I'll start looking at t4 based turbos, different fuel pump setup, and yank converters. Other than that, it's time to buy some more parts.

S475 t6 1.32 96mm version its a sanderson driver side header 2.5inch crossover to log manifold sits behind radiator on passenger no clearance issues with stwering shaft 5.3 block ford mustang on3 fmic twin m15 nozzles before throttle body makes great power so far more than can be put down on street tires i use qa1 coilovers on front vikings in back 8.8 3.55 gear welded up and street driven

Looks good! Probably about where I want to mount mine if it'll clear the shock tower on the 4x4.

You going to run out of injector quickly with e85, go with something bigger. Twin 465 walboros will do well, and upgrade your lines to -10 feed -8 return ptfe lines

Unfortunately no e85 remotely close (3-4 hours) so I'll be running 93. I found a decent price on a cell running twin 340s which from everything I read should be plenty for 60lb injectors and 600whp, so I think I'm gonna go that route. Check on the feed/return lines, I already have some layin around.
