    Ok, First things first. Can this be done as a Straight Swap Engine/Trans/PCM? Or are there other things that I would need to change out? I found a 3.8L V6 Supercharged (L67)(L32) with only 150K on it. <--Beats my 215K Motor.

    Also, Would keep the old Engine for parts. Obviously there are parts I would not be able to use. But would use what I could.

    Well it depends, if its an L67 it should be a direct swap, but if its an L32 i'm not positive if its a direct swap

    A topswap on a 215k motor with a possibly still original trans would scare me more than a little bit.

    Beside would wiring be a bit different? Better off finding a nice low mile motor with SC and tranny from a junkyard and swapping.

    Test compression on both engines.

    That'll tell you more than just guessing. 150K Miles isn't low, under 50-80K is low for a used car engine. Trucks tend to get much higher, much quicker.

    For a 2002, you'll need injector connectors and map connector. Everything else is the same on the engine.

    The trans/pcm should work.
