Help me find a good size for my truck I have a gen3 5.3 and a 4l80 with circle d 3k-3.2k stall still the stock 3.73 gears. It’s a 2008 4wd crew cab I am trying to reach around 700-800 hp the engine build is below. I plan on getting 120lbs injectors and twin 340 pumps in the tank. I just got a Huron t4 kit without the turbo and wastegate so if y’all and any advice I would love to hear about it.

I want this to be a fun strictly street truck to blast around town. I hardly tow but I would like to haul *** reliably. -PAC 1219 valve springs with new valve seals

-Elgin 1840P cam 228/230 112 Lsa

- King main and rod bearings standard size

-Ls9 headgaskets with speed master head studs

-Rings gapped to .026 top and .028 bottom rings for boost/nitrous

-New melling standard pressure oil pump with new pickup tune o ring

-new cam retention plate

-New Elgin LS7 lifters

And new front/rear cover gaskets and crank seals.


need help finding

turbo brand and size
gear size
wastegate brand and size

 

The vsracing billet 7875 can make 815hp to the tire on a mustang dyno. It spools pretty good on 5.3s and 6.0s.

 

What's your budget? Vs racing 78/75 should do it. Our look into something similar from Forced performance.

 

Since I’m at the end I was gonna get a bw or a vsr I don’t really have a budget just want reliable if I can squeeze out enough to get around 800 I would be happy. What about the wastegate? I was looking at eTurbo2 controller and some wastegate maybe a 44size

 

VS has wastegates. 44mm will do. 3.73 gears are good as long as you don't have oversize tires.

 

no oversized been there done that I want a family sleeper only way to tell is hear that turbo woosh by you.
