What's up guys? I know some of you are saying "TX2K14 is one year off!" Yes I know, but this project may just take all that time. Who knows! Anyways I decided to post up over here and on PT.net to get a good deal of advice and opinions here since this will be my first turbo build.

Essentially what I'm starting with is a 2007 Chevrolet Silverado crewcab 4x4. This has been a project truck of about 5 years now between my dad and I. I'm moving away from the supercharger scene because, well they're just inferior to turbocharging as was proved with my recent experience with Kenne Bell. (Couldn't make enough power, and couldn't keep the air-charge temp cool at 20+psi)

I'm also getting away from the aluminum LS motors and moving on to the iron blocks. Essentially what we're aiming for is 1300AWHP at 26-28 pounds of boost. SO, underway from LME right now is a 427LSX shortblock, with a Callies Dragonslayer crank, Callies rods, and a custom set of Wiseco's with heat treating, gas ports, and a .210" wall pin. CR should be about 9:1 with my large chamber heads.

Essentially I'll be running a set of 4 bolt Cadillac LSA's done up by WCCH and ARP 2000 LSX studs. If it pushes water, well that'll warrant some 6 bolt LSX heads but for now I think it should be fine. I'll be pushing the ID1000 injectors I have now until they scream Uncle, and I bet that'll be somewhere around 20 pounds of boost. Should be fun for long enough to let both mine and my dads bank accounts recover.

Haven't had time to spec myself out a cam yet, but I'll probably be doing that here soon. For intake I'll be running a Holley Hi-Ram with a 102mm inlet for the big TB.

I also haven't figured out which turbo kit to go with, but I have decided on a Garrett GT91 to do the dirty work and a big A2A plus some meth. :boobs:

Besides all that crap, I'll be doing a full fuel system upgrade to -10 feed, wiring cleanup, gauges, AMS1000 converted to manifold pressure instead of CO2 reference, and all the other goodies. Hoping to go give a couple of fast guys a run for their money next go around.

I'll be posting lots more info and tons of pics as the ball gets rolling, so feel free to share your thoughts and insightful commentary but at the moment I needed to get a thread started so I wouldn't be too lazy to do so later. Enjoy!

Not a fan of the wheels, but the rest of the build has me sincerely interested. Subscribed :popcorn:
I agree, I'm not too much of a fan of them either, but they hold a 305 Drag Radial pretty well. :shrug:

Kinda unassuming i guess...
Not really sure what else is out there for these trucks that have enough offset to allow the front tires to turn inside the wells without rubbing. Thought about spacers for different wheels, but that would warrant the need for a longer/stiffer stud. When coming off the transbrake the right front tire tends to wheel hop some from spinning, and considering the thing weighs around 6K pounds there's an excessive amount of force being exerted everywhere.

Wheels are controversial, no? :)

Nice build. :beer: I would keep the c02 on the AMS though, it'll be a lot more responsive. :twocents:

I see you're from here in Roswell. I'm guessing this is the "hot tub time machine" I hear about? :lol:

Details on current setup before you change it?

I appreciate the opinion. I can deal with the .5 psi inaccuracy though. If it proves to be too much of a burden I'll probably see what I can do with the CO2.

Good luck Mr. Hatcher.
Ah, thank you Mr. Bell. I'll be needing it.

Get it done!

Starting to!

Who is gonna tune it?
That would be myself.

Indeed it is! What gave it away dammit lol. Current details= Junk LS3 block. 4" stroke Eagle crank, Eagle H-Beams, and a couple detonated Diamond boost pistons. Same heads as going on this engine, junk Comp cam, and a 3.6 liter Kenne Bell supercharger originally made for 2010 and up Camaro's. It was a slick setup and it got lots of oohs and ahs, but just didn't have the performance capability that was required. So it's time to really get nitty gritty with this bitch.

As I've been told my 4L80E will be full of hatred towards the newfound power.

Opinions on poking the Downpipe off the turbo right out the hood?

I'd just do it under. Hard to be incognito with a pipe in the hood.
True. I was just thinking about where I'd route the DP. I don't think I can get it over the rear axle without problems since the teuck is lowered.

You don't want to cut fenders out but you'll cut the hood?
Lol precisely! I guess I'm not understanding what you're saying about cutting the fenders. Even though I don't like the wheels, they serve a purpose and do their job. Even if I had the option to go with a wider wheel I wouldn't. Not only would it require cutting the inner fender, it would also require notching the frame out. The place it would rub is literally right where the fender well bolts to the frame rail. It's kind of a bitch, but that's why GM really doesn't run wider than an 8" OEM wheel from the factory. But you're thinking, why don't you simply offset the new wheels more when they're manufactured? If I did that then I'd surely tear up a fender from suspension compressing/decompressing and they'd need to be pulled. I don't know about you but I've never seen an NNBS with pulled fenders.

Also I might consider cutting a hole in the lower side of the fender right behind the front tire for the DP ;) so what you said isn't totally true lol

Took the thoughts right out of my head about Land Shark. Hmm....
