He’s got an in with the local junkyard and they usually don’t mind him pulling the valve covers to take a look inside, but he realizes that most junkyards won’t allow that, so he gives us other ways to check to see whether or not the engine is worth our time. Us old timers would never think if picking up a high mileage engine that we were planning on building to pump out more than 700 horses without tearing it down and rebuilding it.

How to Pick a Reliable High Mileage Junkyard Engine without Rebuilding It Part Three will finish the build by finishing up the exhaust system. Part Two will delve into the intake, valve train, and fuel system upgrades required for an 800 HP twin turbo engine. This, Part One, will go into playing around a bit with the factory tune and then setting up the exhaust manifolds for a twin turbo setup. We’re going to do this as a three part series. I’m going to walk you through the whole process he went through to turn this rather staid and laid back truck into an 800 HP monster. This one’s got over 310k miles on the odometer, and all he replaced was the oil pump and the valve springs, which he only replaced because he ended up sticking two (yes, TWO) turbos on it. The 6.0 Liter LS engine that will be receiving twin turbos.

He put together a series of videos to help you figure out one way to relatively cheaply turn that somewhat boring six liter into a screaming monster without the expense of rebuilding the engine. The 4L80E was recently rebuilt and had a Trans-Go Transmission Correction Kit installed. Introducing the Justin Sane Racing Products Parts Truck BuildĬraig recently went out and picked up a 20 HD with a six liter LS and a 4L80E automatic transmission because several of his customers were wondering what they should do to get more power and torque out of the engines in their GM trucks. I’ll walk you through one of Craig’s latest projects in this article. Additionally, when he’s finished playing with the engines, they produce anywhere from 800 to more than 1300 HP. What’s insane about that? He doesn’t rebuild them. For instance, other than one (which I will write about shortly), all of his previous projects have involved junkyard LS engines, most of which have well over 100k miles on the odometer.
My buddy Craig Poust, owner of Justin Sane Racing Products, is known for doing insane things to engines. Over the course of three articles we will follow along while Craig Poust installs twin turbos in this 20 HD, turning it into a 700-800 HP truck.
