68 5.3 ls twin turbo build

[portworks]

Well its been a year of driving and having fun after the ls swap,; but now its time for more power !
Started as a frame off build last year. 64, 000mi 2003 4l60 and 5.3 with a brian tooley 216/220-568 @110 cam with springs and push rods, 1 5/8 doug thorley headers, 9" ford posi 4.11 And all gaskets and seals of course ! Which i am now going to sell the headers,4l60e , custom intake and blazer intank fuel pump assy, If anyones Iinterested !!!
Now I am going with billet internals,log style manifolds, twin intercooled on3 70/68 t4 turbos, 4l80e . If anyone cares to follow the build, I will post some pics.

what's better then one turbo two turbos

[sammygroundzero]

How much are u asking for headers

Should be a fun drive with boost

[portworks]

Headers $450 perfect condition, original box, and all paperwork!

Got any idle clips?? That thing must sound like a Harley with that cam!

[portworks]

I don't. It sounds pretty good ,but not as lopey as you would think due to the short duration.

[slotard]

You could probably build the 60 to take the power of the turbos.

You probably could but not for the price you could do it with an 80 for. Even then I would still consider the 60 to be on borrowed time. Outside of the size difference I don't think there really is a down side to an 80.

[portworks]

I agree, I don't believe the 60 would last very long, aand will make someone a really nice transmission with only sixty four thousand miles on it. I just want the added possible insurance with the 80.
I sent an email to this site to possibly move this thread over to the LSX swap section, with no reply ! ? Any Iinput on this ?

[tinydb84]

Just PM one of the mods

[69trk]

watching this... im hoping to have my single turbo done this year...

[portworks]

Slick truck 69trk !

So why not just flip the headers and point them upwards then make new flanges that have your wastegates mounted right to them. Log manifolds are for boats and foreign cars with no room. You will hurt your performance doing that unless of course you plan to run low boost like 5psi.

[Super73]

Nice looking truck. It sounds like a cool build. If interested in shooting the stuff.. Pm me and I will send you my number. I'd like to talk to you about the build.

[79 big block]

Interested to see how the on3 turbos do, will definately be watching this thread.

[portworks]

Been busy building customers promod motor. Will be starting back soon, and will post some more build pics. Thanks for the interest !

[portworks]

Some update pics. Decided to run headers instead of logs after all.
So the turbos are mocked up, and the intercooler also. Slowly but surely making progress !

[79 big block]

Nothing wrong with slow progress, there is no time limit on building a hot rod.

[slowtruck]

Looking good! I have the same headers to use on my build.

[Wasted Income]

Looks good. Following along.

Might as well do an 80E right away. A stock or even "built" 4L60E is no match for a turbo LS on sticky tires in a heavy truck.

I know this for fact. lol.

[portworks]

I have an 80 E, just need to find the time and money to build it! Thanks for the interest in my build !

[Tom Vogel]

So I guess we will be seeing you on Street Outlaws next season?

[iceship]

Looks good... im looking into a rear mount setup. .

[portworks]

Street outlaws are badass !
I have alot of other projects going on, so its going slow !

The only person worth actually believing on that show is Lutz (which is why he doesn't say much). Legit 6 second car.
Can't call a show Street Outlaws when you pull the car off a trailer to run. Cops aren't that stupid.

The turbo 5.3 is cool tho.
