Theoretically, should be plug &play with OEM GT parts.
Programming will be needed.
PCM - Reset learned parameters, VIN and PATS. Forscan can do PATS, but I think the VIN programming has been removed. I dont think VIN programming worked on 05-09 anyway.

As much as I love the 3v and hate to say this…… if you are going for power, it might be cheaper just to swap to a coyote. Either way look at this auction site and buy a complete salvage donor. I know that they offer brokers for a fixed price if your only looking to make one purchase.

Coyote swap is NOT plug & play. And even harder if you need to pass smog check. Speaking from first hand experience here. lol

I was just going to get a wrecked one and swap the drivetrain in, a coyote motor or car is still a bit out of reach but what I want is to take the 3v and put it In my running 4.0. Then take the wrecked gt and on the damaged swap my twin turbo 4.0 and use it has a drift car/ track car. So wiring should t be an issue because I’d have the whole car and just need a few components possibly based on where the collision was.
