The GNX only had one turbo like was said above and had a different rear suspension. It used a ladder bar that went from the rear end to the center of the car. When launching, the rear end would accually rises up.
IF I were to own something other than a Mopar, it would be a GN. I'm pretty sure they put the turbo V6 in some Monte Carlo's too. There was one in a junk yard close to where I grew up.
My cousins husband has a GN that he bought new. I don't know all of the mods he's done but he did say that it has the biggest turbo he could find that still looks stock. He said his dyno'd at 450hp. I'm trying to remember what he said he ran in the 1/4. I want to say low 11's or high 10's. Pretty impresive for a car that looks more like a G-machine than a drag car. His is lowered with 17" wheels and big swaybars. It's one of the nicer ones I've seen. I don't think it's been driven for quite awhile since he had kids. I did get a ride in it once but he just had low octain pump gas in it so he didn't get on it all that much.
