ls 5.3 Engine build

[Carlyle23]

Just purchased a low mileage 5.3 and I would like to keep it fuel injected. I could use some assistance as far as what parts I'm gonna need and what issues I may run in to. Its just the engine no harness, ecm, or accessories.

You will need to make an engine harness or buy one for your specific car. You will also need the ECM, and make sure aall the sensors are there. If you have a drive by wire throttle body, you will have to change it to a cable driven one. You will have have to have the ecm tuned to work with the car. They will have to delete the vats system and transmission control for sure, unless you are going to use a 4l60e or 4l80e trans.
