    What 4.2 turbo to do direct replacement with no mods

    I have not been able to find an answer to my question - Is my turbo bad? I just bought a 1996 GQ 4.2 turbo. It is super slow, 15-22 seconds 0-60mph. I hold up traffic every time I travel. Top speed is only 63mph. Runs smooth and has a decent pull at low rpm's. Low speeds runs great, and runs great if you go slow and accelerate slowly. very slowly.

    I am assuming at this point the turbo is bad. I am a lifelong petrol and marine mechanic, but not a turbo guy and only slightly a diesel guy.

    I would like to find an affordable turbo to swap out to see if this is the issue. If I can increase performance a little without additional mods that would be great.

    Any advice?
