Default 5.3 Swap into a project car.

Taking a L33 5.3 out of a 2005 Sliverado to transplan into a project car. I have the ECM, entire engine harness and gas peddle (DBW). Do I attempt to use the stock stuff or buy an aftermarket like Megasquirt, Holley ect? Is there a basic plug and play that will make this transplant less painful? One that is not priced out of wack?

At some point I plan to go with a turbo so the system will need to be flexible enough to allow the turbo.

Is this engine a 24x or a 58X?

Thanx for the help!

The stock harness can be made to work either by repinning the body connectors or completely stripping and rebuilding the harness. Aftermarket is always available for both stock and aftermarket ECM/PCMs

The stock PCM will be fine with boost

Look at the crank sensor to tell the reluctor tooth count. Black is 24x, gray 58x. Its not a bad idea to pull the sensor and visually check the ring too
