I am planning to rebuild my engine myself when the time comes. Im not planning any major upgrades/changes want to keep stock engine & stock twins on stock ecu.
When that engine is put back in the car is there any/much tuning to be done for it to run right? If so can this be done diy or will it need to go somewhere for it?
Nope, just make sure you got the right plugs, oil etc, run it in correctly and you should be fine
