Junk Yard LS Engine for your project car
I have dug up a lot of swaps over the internet and at the junk yard first hand. I can tell you hands down the best way to go is a running driving car you can drive into your garage and strip apart as needed. And don’t get ride of anything until you have the engine running and the car driving around for a at least a month. Never know when the tiny unknown bracket that cant be purchased breaks or is lost and you have no way to repair it without finding another junk yard car to remove it from.
I would recommend if your not going to go this wrote its best to get as much as possible from the donor car. Remember to grab the full wiring harness and all the boxes and devices connected to it. If you don’t know what its for chances are you need it. This can be a real pain if you are grabbing the engine out of a Escalade.
Which is a great donor since it has about 340hp stock and 6 liters engine with 15 degree cathedral port heads. With a little head work and cam work the LQ9 could make one hell of a ground ponder and still smooth enough to drive around town a little. These motors respond amazingly well to low boost levels from turbos or super chargers. Boosted application can punch 500+ hp to the ground with little effort. This is no small amount of power but the work to get there is not nearly as much as you might think.
Now the second best way to get an engine is from a junkyard that deals in these engines for swaps. My local junkyards have a few LS motors sitting next to the counter with wiring and computer next to them. The ability to start the engine right up and show its working. Also showing you what is need when the engine is installed in the car.
Here is a great article that covers finding LS engine in the junk yard.
