Guys, seems like the turbo section has been a little slow lately, so I'll post my next plan (they seem to change alot).
I got the 5.3 in the '92 rcss and its great, but now a new set up came along.
This what I am doing.
Forged 347, Diamond pistons, Speed Pro rings, Eagle rods, ARP rod bolts, Patriot 72cc heads with 2.05/1.57s, head studs, 60lb injectors, twin Walbros from a sumped tank, using the truck intake until I can do a Victor Jr.,
STS style turbo with a PT74 mounted in the bed, fmic, 3200 Vig stall, 4L65, 3:08s, already have Detroit true trac, and Caltracs.
Even though there is plenty of room under the hood, I feel the need to put it in the back just to keep after the na-sayers.
Goal is to run 10.99. This set up was in a crew cab and went 12's @ 10psi and there was room for improvement in many areas. I also am willing to do 15psi too if I need to.
Motor will be in a week, but the turbo will take me a month or so as we are full up with cars.
Any comments welcome. Think I can do it????

 

Sounds like your gonna need someone to race in the lane next to you who can keep up! If you blow our 5.3 I'll sell you mine as soon as I swap it out!

 

sound sweet....that thing is gonna be a beast...keep us posted

 

Nice. I caint wait to the the turbo in the bed setup. So are you going to do a tailgarte mounted intercooler to go along with it????

 

Come on now. No super throw down intercooler mounted where the tailgate was
If there was more flow in the front of the bed I would put one there though. I dont think there is enough flow to cool the charge air well enough, so it should be a typical front mount intercooler.
You know, that would be so much easier though.

 

Cool deal billy, keep us posted on your progress. I think you can do 10.99

 

I say a 76mm turbo,75lb injectors and a meth kit.I think the 74mm will stall on you.

Also,tune it to the max. -No fluff tuning

Remember this

 

You bet I do.
I was hoping to avoid the 75s if I could.
I will see how far the 74 will go. Its supposed to be good for "950hp" according to Precision.

 

75's are real easy in a SD tune

 

Actually, I think there is a ton of air flow at the front of the bed when at speed (upward). Have you ever seen a soft tonneau cover when going down the highway? On my S-10, it was all ballooned up in the front and sucked down in the rear. I bet you would be surprised at how much air flow there is.
