The difference is where the sock attaches and the shape of the inlet.

Not sure of how much rwhp they will support, but I'm thinking north of 700rwhp. Someone else will need to chime in on that.

Are you running both pumps all the time, or do you use a pressure switch to turn the second pump on under boost?
Thanks for all the info. It's been very helpful.

I have a few more questions if you don't mind.
1. Do you use a 3/8" fuel supply line?
2. Have you ever blown a stock plastic intake from boost?
3. Do you generally use the stock throttle body?
4. I know you generally use a single turbo, but if you were to do a 5.3 with twins, which ones would you use? LS9 cam, 799 heads.

I have a 54 Chevy 5 window pickup that I bought to use as a shop truck. I just picked up a junkyard 5.3l to go in it and plan to add some boost, but I really like the look of twins. So right now I'm in the process of getting all the parts together.
Thanks for sharing your advice and info with us.

Hey matt.
For the dual walbro. Did you use a 8an for the feed and use the stock feed as return. And the wiring. Do you need a hot wire kit for the 93 f body thanks..

2. Have you ever blown a stock plastic intake from boost? no sir, and i have topped out 3 bar map sensors on the ls1/ls6 and truck intakes
3. Do you generally use the stock throttle body? yes every time nothig else
4. I know you generally use a single turbo, but if you were to do a 5.3 with twins, which ones would you use? LS9 cam, 799 heads. i would do a small converter and twin 61-66mm units from CX racing, all out drag i would try smaller AR 5.3's and swing the motor high

in what the firebird?
we did stock line and returnless for a while, now its return on a half inch hose, and 3/8 return, its not enough now at 18-19psi, going to try a 255 and a 400lph we have laying around and a REAL Y fitting instead of a T thats in there now, see if it will work for fun before going nuts with a huge single pump or something.

actually the car had a sub in it at one point, so we used the like 4-6g wire for the pumps in the tank

Base gt45 is 70mm. I asked VS the same thing and this is what i got back.

" The turbo is upgradable to the 76mm extra 150.00, 80mm extra 200.00 88mm extra 300.00"

You'd have to call and ask. He doesn't have it listed on his website. I have found the gt45 they use on ebay and its about $250 for the one that's in the base kit.
