Re: 68 5.3 ls twin turbo build

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

Re: 68 5.3 ls twin turbo build

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.

Re: 68 5.3 ls twin turbo build

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 ?

Re: 68 5.3 ls twin turbo build

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.

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.

Re: 68 5.3 ls twin turbo build

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 !

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

Re: 68 5.3 ls twin turbo build

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.

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.
